I purchased this set through ebay and it works perfectly
just needed to re-order the wires
re-pinning should only be required if it is on Pre-LCI. That's the place I ordered from too before the price and shipping hikes too.

Oh yes ... My car is pre LCI so I needed to re pin


I'm starting to look at suspension options as I near 100k miles

I don't think I will miss edc ... Or will I?

What are my top 3 options for 99% street use?

While I do miss the versatility of EDC, the settings didn't feel dramatically different enough. It made it harder to justify the limitations of aftermarket options just for the sake of the button.

Balance comfort and handling
I can handle a bit stiffer ride but I am just commuting around so I don't demand too much from the car
I wouldn't mind a slight drop from stock height

I don't want to tinker around too much
Unless if I miraculously start getting the wife's blessing to go out with the boys for drives or even track days ... But with our second baby I don't see that happening anytime soon

EDC is useless — not worth keeping imo.

Öhlins sound perfect for you. More comfortable than OE, able to lower the car as much as you'd ever want.

If the car is purely street driven, and you don't care about getting more than ~-2 degrees of front camber, this is what I'd get:

Ohlins RT sounds like the right choice.

The one 911r's user avatar911r linked is just a preassembled one with stock refreshed top hats.

In your shoes, I would get the off-the-shelf Ohlins RT, add a vorschlag camber kit and poly rear top mounts.
[header="Fall 2022"][/header]
It’s been awhile. Since my last post, I basically haven’t done anything.


[header="Sonoma Raceway 2022-11-20"][/header]

Good ole Sears Point. 30minutes away from home, highly technical track that is very rewarding with little to no runoff for mistakes. There are only a few places where you can readjust and the rest of the course is all rhythm. Many of the corners chain together and one mistake early on, hurts almost half the lap.

This marked the first time using caliper temp stickers. From what I’ve read online, my calipers are doing okay. They better be considering it is almost Winter and ambient temps were in the low 60s!

Image hosted on: i.imgur.com

This also marked the first time I’ve actually used the RE71R beyond the first session. They offer a lot of grip compared to heat-cycled RS4s! I still didn’t get comfortable to even reach the limit of these tires yet. Hopefully next time around!

I ended up running 4 sessions, 2nd session gathered my personal best at 1:56.62 with a lot of room. I hope I can come back soon as I was driving pretty sloppy to get that time.

Overall, it was fun to meet new folks, and having the 3 garage slots together with friends was a fun day. I definitely enjoyed it.

[header="Winter’s plan"][/header]
The game plan for winter is suspension! I hope to swap springs 450/800 sometime in December and get the suspension re-valved if that doesn’t solve my weird freeway bumps while being supple for backroad driving.

## Suspension
This is a long rabbit hole I’ve been everywhere with. The car feels wonderful on 600/900 on track but it gets a litle rough on the streets of SF and back roads. Even with the current dampers, it feels like it is not handling the high amplitude/low frequency bumps.

The plan is to try out 450/800 springs, and if that still feels odd, ship back the MCS 2WNR dampers back to MCS for a piston update and re-valving.


On another note, I still have these parts laying around now too. Been lagging on those solid subframe bushings, its been 2 years. :lol:

The "pile" of parts is slightly growing
  • Slon VANOS covers
  • Bimmerworld Solid Subframe bushings
  • BMW Motorsports 4.10 FD —Thanks to Jordan!
  • Misc pieces for 2.25in ID to 60mm ID Swift springs
  • new GC rear spring perch rod for running 8" length springs
[header="Spring 2023"][/header]
As we enter 1 month of Spring 2023, I have done absolutely nothing with the car since the last post. Weather in California has been odd to say the least and traveling with my wife has taken priority the last few months.

[header="Well that didn’t go as winter plan intended"][/header]
My initial winter plan was to get the suspension overhaul done between my previous post and now.

# Recap
  • Switch to roughly 450/800 spring rates.
  • readjust damper tuning to match new spring rates
  • send in MCS dampers for rebuild as we approach 5yrs/15k miles.

Timing pushed things back and here we are now. At least there has been progress as I ordered Swift 8k/14k springs for my car in the middle of March. I hope to change the springs sometime in May.

[header="Fidgety"][/header]
In the past, I have toyed with the idea of a M performance exhaust on my car. I didn't want to buy new but if one ever pop up locally in the classifieds, I planned on getting it. In late March, when @Sam notified me that a used M performance exhaust v2 was for sale locally, I immediately hopped on it.

I know what you are thinking: “But Derbo, you already have a Supersprint F1 race exhaust and it passes 90dB Laguna Seca! Why are are you switching an already perfect exhaust?”

There are a couple of reasons in no particular order:
  • Weight. At 30lbs or so, this is surprisingly 12lbs lighter than the SS F1 race exhaust and 19lbs lighter than stock. I did not expect that large of a difference compared to the SS F1 Race but Inconel appears to be light as hell!
  • Materials. The material used on the MPE intrigued me. Inconel is unique alloy and the titanium tips are a nice touch too.
  • MSRP. While at one point the dealers were selling at $2300, it is back to the original $4500 again. Buying this used meant I would be paying less than half which I appreciated.
  • Volume. While the SS F1 Race is quieter than majority exhausts for our cars, I disliked the cold start drone as well as drone when under load below 2500RPM. The MPE volume in comparison to what I remember of my OEM 4pipe mod but a little quieter. There is just no drone with the MPE where my OEM 4pipe did have a little more volume and drone under low RPM and load. The MPE provides a different tone without drone. The lack of volume is unfortunately, but I think the benefits of that outweigh the lack of volume at my stage in life haha. I’ll be one of the quietest cars on track since the SS F1 exhaust was already quiet as hell.
  • THE TIPS. This is the most important reason: it has four more ///M badges. :lol: as @richbot said, this is best badge/dollar ratio in adding additional +5hp badges.

# Installation
As with axle back installs, having a Lisle rubber hanger remover came in clutch in saving a lot of headache removing the rubber hangers. No fussing with fitment, it just fits perfectly with tips in the right spot.

# Impressions
Volume: Stock like but honestly I don't remember what stock sounds like. Cold start isn’t droning, and no drone at all. The volume above 4500rpm seems similar to stock and while it might not be as loud as I would have like, I value the volume for cold starts/low rpm more than that. Volume is a touch low for helmet use but induction noise is all there for knowing where in the RPM I am at.

As it stands right now, I'm still indifferent about which exhaust to keep. I love the usability of the MPE but I rarely drive the car on the street. The OEM+ factor does play a role and it does have fancy +20HP ///M badges haha. I'm leaning towards selling the SS F1 Race exhaust but suspect I'll hold onto both for a little bit until needed.

Here is what it sounds like on the track at 130mph to 82-83mph.

[header="Thunderhill Cyclone 2024-04-24 CFRA"][/header]

The CFRA 2023 season kicks off with a Monday Thunderhill! One could guess why there was low car count. It ended up being 11 cars per run group. Not bad at all!

My primary focus for this track day: to have fun and build back up confidence at the limit! This marks the second day on RE71R old stock from Tirerack and it's still a trip to me. I'm still finding where the limits are and trying to weed through the mental roadblocks. I think I'm overbraking, not enough speed around corners and on the throttle too slow or too early. But at the end of the day, I'm just working my way back to pre-fall-2020 Derek speeds and hopefully steadily improving to break past that too. Either way had fun!

Temperature at 80F ambient, it was good enough to have time without dying in heat. I managed to scare up a 2:07:279 and I know there is plenty more to gain. Thank you to slcook54's user avatarslcook54 dparm's user avatardparm Ximian's user avatarXimian for additional analysis after watching my POTD video.

#Misc
I did manage to lost my front left driver felt panel due to a slight miscalculation of Turn 8. I'm debating if I want to order a metal under tray or just buying a left felt panel and moving on.

[header="What lies ahead this year"][/header]

#Priority One
448/784lbs spring swap.
Alignment
Damper tuning will be reset and will require plenty of testing to gain the optimal street and track damper settings.
https://motoiq.com/how-to-adjust-your-shocks-part-two-double-adjustable-shocks/
Mr. Mike has happily shown his rule of thumb: Run the most compression with no ill effects and with the least amount of rebound also with no ill effects.

# Priority Two
Maintenance may come as well and I may order gray VC from Deansbimmer and do the slon VANOS covers.
After that, lets start looking into my rim setup and finally subframe/final drive situation.

The "pile" of parts is slightly growing
  • Slon VANOS covers
  • Bimmerworld Solid Subframe bushings
  • BMW Motorsports 4.10 FD —Thanks to Jordan!
  • Misc pieces for 2.25in ID to 60mm ID Swift springs
  • new GC rear spring perch rod for running 8" length springs
  • Swift 6" 60mm ID 8Kg/mm front springs
  • Swift 8" 60mm ID 14Kg/mm rear springs
  • BBS GT4 staggered set for street. :drink:

[header="Summer 2023"][/header]
As we head in middle of summer, time for an update!

In the previous post, I forgot to mention I had a little slip up at Turn 8 at Thunderhill. I was a little antsy and turned a tad too early into the turn. Unfortunately, I was committed and past the apex is just a concrete drop resulting in a fun loud noise and a hop. I got lucky with the aftermath damage but I managed to destroy my under tray and bend 2 of my wheels. I ordered two new Titan7 wheels after they were reported to be 1 minor bend and 1 trashed. The minor bend one will end up being a spare. Since it was time for an alignment check, this was a perfect opportunity to get going on my suspension changes going.

Image hosted on: i.imgur.com

[header="Minor changes ahead"][/header]

## Suspension changes
Here we are, finally installing a set of springs. I have a few objectives here. The first and foremost was to soften the car but still stiffer than my original 400/700 lb/in setup. The other was moving the ratio closer back to flat ride a bit as the car felt odd on freeway overpass junction bumps, etc at high vehicle speeds. The ride quality left a lot of confidence off the table.

Image hosted on: i.imgur.com
  • 8KG/mm 6" free length and 14KG/mm 8" free length springs
  • 2.5" hyperco helper springs
  • new standard length Ground control rear weight jack rods to accommodate 8" springs. (Previously cut them to accommodate 9" springs)

Overall, the install was uneventful as it was simply a spring and threaded rod swap.

Alignment at VT Motorworks. I opted for about -3/-2 F/R camber, 0 toe up front and minimal toe in the rear, 0.05'. It is a mild alignment and should help with turn in while keeping it fairly stable at high speeds compared to a toe out front alignment. Initial impressions are this is the sweet spot for a "Dual Duty" spring rate. It's just stiff enough for track use for 3-4 events /year but still tolerable on the road. I'm loving it so far! I think I found a dampening setup that will work and mitigating the large oscillations when going over overpass junctions bumps at over 70mph. In turn, this will also help stabilize the car at high speed uneven surfaces on track days! Win win!

Of course when I come home from the shop, car goes lights up on the dash; a bad rear wheel sensor. After an initial check, I'm pretty sure the other rear side failed compared to the original one that failed last time around.

Image hosted on: i.imgur.com

##Tray
So because of my 2 wheel offroad excursion, I also decided to get a Pinnacle Motorsports under tray.

Pros: I like the better ground clearance and lightweight metal tray.
Cons: I don't like how all these metal trays seem to buckle the front bumper and even leaves an odd gap in the middle.

For now this will do, perhaps I'll think of something to fab up the gap as I dont have a lip to cover the hole up or maybe look into the turner motorsports one. That one looks like it addresses my cons about this piece but additional money.

The goal of the day was to tune my suspension and get a feel for how fast this new repaved track felt like. The initial street settings 9R/8C, 8R/5C settings felt pretty good and I added about 3 more clicks of compression in the rear. Since the private day had us running at the top of the hour, I felt like we had plenty of time to test! I didn't expect to reach the suspension settings so quickly.

After 2 sessions, I even ended up with being in the 1:42s! I was excited and decided to try for a faster lap mid-afternoon when the tank light was just about to trigger. I threw down a 1:41.80 and was stoked. Car felt soft enough to grip while stiff enough to not feel like I was rolling over. Final session, I decided to take out my wife's M4 comp out and did a 1:41.1 without even trying hard..Those cars are so fast.

slcook54's user avatarslcook54 was a celebrity with some of the folks there and pushing some 1:37s borderline 1:36s! I think next time around he is going to hit that and then some!

Post-analysis: what attributes me going from 1:45.680 to 1:41.80?

PS4S vs RE71R
Change spring rates? 400/700 to 448/784
ST60 DTC-60 to APRacing 9660 3.12
Better nut behind the wheel

I would argue that the biggest one is the tires and driving confidence. I hope to continue this trend and fine tune the lap even more next month! I'm very happy with that time as I always felt 1:45 wasn't good enough.


# Spare Diff
As part of the 4.10 upgrade in the future (whenever that may be), I split a stock E92 diff with an E46 buddy of mine. He took the 3.85 and I kept the rest of the parts. I haven't decided what I want to do yet, I suspect I may build a custom ZF LSD that is better for track use but has OEM-like maintenance intervals. This plus solid subframes will be cherry on top to a fun "M3CS".

cool stuff and congrats on your time drop!

just out of curiosity though, I noticed your speedometer only has mph. what's up with that? mine shows mph and kph... how come you made that mod?

anyways, I really enjoyed reading through this thread, great trove of knowledge - been seeing quite a few M3s since moving up to the bay, hopefully I'll see yours around sometime :D

The Venoxy gauges are cleaner! Some european market clusters only show Km/h and I thought it looks cleaner without the duality of units.

Coming up!

11/18/2023 CFRA Sonoma Raceway to finish off the year of events for me.

No changes to the car before the track day, but I expect I'll be rebuilding the MCS dampers as we hit 5 year mark and 15k miles. Not to mention there are a good amount of hours on track as well. It's due!

I was cleaning up the wheels and realized I'm missing a hubcentric ring for one of them. Guess I'll have to order one. I can't wait to go back to these wheels for street use. :)

This past weekend was the last CFRA-hosted HPDE event for the season at Sonoma Raceway! I was hoping to follow my progress from Laguna to here but the weather did not want to participate! It was pouring! It did dry up 2nd to last session but the last session drizzled again.

Overall it was a learning experience in the rain, the first time in extremely wet. It was an anti-climatic way to end the season but I’m happy to continue to next year and onwards.

Winter plans:
I hope to rebuild the MCS 2WNR this winter as it’s been 5yrs/15k with a good amount of track hours in there.

I hope to also purchase parts for the spare LSD and get that going with the solid subframe bushings.

Maintenance items coming up sooner or later: Cooling system, Valve/Vanos covers.

After that, I'll see how I feel about this car. My mind is in one of those ruts where you want to sell it, but you dont either cause replacing it would be impossible. Maybe I’ll have a decision on what I want to do next time I post. Till next time!

MCS Rebuild
J'ai mentionné dans mon dernier post que les amortisseurs MCS devaient être reconstruits selon la recommandation de 5 ans / 15 km d'intervalle. J'avais des inquiétudes au sujet des amortisseurs car la voiture se sentirait sous-équipée sur certaines grosses bosses de l'autoroute. Je voulais que les amortisseurs de voiture fonctionnent comme s'ils étaient amortis de manière critique, pas sous l'humidité.

Donc, à la mi-décembre, j'ai retiré mes amortisseurs 2WNR de la voiture, je les ai giflés sur les amortisseurs d'origine et je les ai expédiés à MCS pour une reconstruction.
Image hosted on: i.imgur.com

Après avoir parlé du comportement de la voiture après les chocs, Wyatt-MCS a recommandé que je mette à jour le dernier design de piston 2021 pour obtenir un rebond plus linéaire. Comme il était déjà en service de reconstruction, ce serait le moment de le faire. Le service MCS a également découvert que l'arbre de l'amortisseur avant droit était légèrement plié. C'est bien que je l'aie envoyé pour qu'il puisse être remplacé ! J'ai également acheté des butées de bosse aussi bien parce que je l'ai trouvé étrange que MCS jamais inclus avec. Black bump stops look assez cool!

Image hosted on: i.imgur.com

Les amortisseurs reconstruits sont revenus en ma possession vers la fin de janvier après qu'ils aient commencé à l'entretenir après les vacances du Nouvel An. Avant que j'ai eu le temps d'installer les amortisseurs, je me suis lancé dans un projet parallèle.

[en-tête"Temps d'échappement"][/en-tête]
Je ne peux vraiment pas arrêter de tripoter, hein ? Alors que l'échappement M Performance est tout simplement amusant pour la rue, je savais que mon expérience de piste était trop calme. Je suis tombé sur un xpipe "Supersprint" sur le forum des petites annonces à la fin de janvier et j'ai décidé de l'acheter. Creusant un peu plus profond, le xpipe est une pièce de pré-production évolutive. J'ai demandé à Evolve pour plus d'informations s'ils ont des détails plus amusants sur le xpipe. Je sais qu'il a échangé quelques mains ici sur les forums. Quoi qu'il en soit, j'ai été ravi d'avoir un supersprint fait xpipe à coupler avec l'échappement F1 Race. C'était presque comme la configuration d'échappement Supersprint complète du budget et cela convenait mieux à mes besoins. Il utilisait des connecteurs OEM pour que je puisse mettre un échappement arrière d'origine si nécessaire, et il avait 200cpsi chats pour réduire l'odeur plus que les versions de course Supersprint 100 cellules. Pour moi, cela ressemblait à la configuration d'échappement Goldilocks.

Installation
L'installation était assez simple et j'ai été heureux d'utiliser un ascenseur pour faire cela! a aurait été douloureux si ce n'était pas le cas. Auparavant, je faisais fonctionner Alpine phase 1 tune et l'avantage était que Alex charge pour la mélodie initiale, et les demandes de fichiers de tuning supplémentaires étaient gratuits même si c'est étape 2. C'était le moyen le plus financier d'empêcher un CEL tout en gagnant un peu de puissance du xpipe. Cela a réduit les frais généraux pour passer à une configuration d'étape 2.

Et avant que quelqu'un demande, le dissipateur thermique de diff est en effet endommagé. Il sera remplacé lorsque je passerai à une configuration 4.1 FD.

[en-tête"MCS Damper Impressions"][/en-tête]
J’avais un véritable objectif en tête : s’assurer que les grosses bosses à grande vitesse seraient amorties de manière critique et non sous-équipées. Après avoir réglé les amortisseurs au point de départ recommandé de 8 rebonds, 4 compressions, j'ai immédiatement remarqué que la voiture était plus conforme mais aussi plus rigide. Je crois que c'est dû à la courbe d'amortissement plus linéaire mais je n'en sais pas assez pour faire cette conclusion. Dans l’ensemble, je suis très heureux de la façon dont la voiture se comporte à des vitesses élevées et travaille sur le réglage fin de la faible vitesse du véhicule, les bosses de vitesse d’amortisseur élevé. C’est dans une bien meilleure position qu’avant la reconstruction.

[en-tête"Impressions d'échappement"][/en-tête]
Je peux dire que le BARK est là ! Le volume supplémentaire dans la cabine est plus fort que je voudrais sous 2000RPM, mais au-dessus de cela, il semble incroyable. Je l'aime jusqu'à présent. Laguna Seca arrive bientôt et j'espère obtenir une vérification du son pour voir où il se trouve au T5. C'est probablement l'une des configurations xpipe les plus silencieuses, mais plus bruyante que la configuration Akra EVO.

Eh bien, je suppose que je n'ai pas mis à jour cela depuis longtemps! Dans le post d'aujourd'hui, je vais discuter de ce qui s'est passé depuis février et où je me dirige!

Dyno mars 2024
Un ami à moi a organisé une journée de dyno et m'a invité à participer. Je me suis dit pourquoi pas !? Je viens d'installer Evolve Xpipe et Alpine Stage 2, voyons ce qu'il peut faire! Comme mesure préventive, j'ai remplacé mes bougies d'allumage car il y avait environ 25K miles sur le plateau actuel. Ces voitures aiment avoir des prises fraîches et c'était une bonne idée d'en avoir de nouvelles pour un dyno.

Les résultats étaient en fait plus élevés que prévu.

406whp 300tq! C'était une surprise et sur un dyno Mustang aussi! Je n'ai pas de comparaisons d'autres châssis E9x sur ce dyno donc je vais l'accepter! La voiture a l'impression d'avoir plus de milieu de gamme et aussi plus de vitesse haut de gamme.

Laguna Seca 04-01-2024
En avril, nous étions de retour sur la piste ! Aujourd'hui était un jour de 105dB et je voulais voir à quel point ma configuration actuelle d'échappement était bruyante. Au cas où d'autres ne liraient pas les messages précédents ci-dessus, je cours Evolve Xpipe avec échappement Supersprint F1 Race. J'ai demandé au directeur de course de signaler ma voiture pour les tests lors d'une des séances de l'après-midi. Ils m’ont demandé de courir par Turn5 sans voiture quelques tours afin que le stand puisse obtenir une lecture précise. Les résultats ? 93.9dB. Juste assez élevé pour échouer un jour de 92dB! Je pense que je pourrais probablement passer avec un début de service ou rester à gauche sur la sortie T5. Ma femme s'habitue à son M4 ultra rapide en stock!

Changements de voiture
Les pneus RE71R (pas RS) estampillés 2019 étaient à leur 5ème jour aujourd'hui et en route pour la sortie! Même si la voiture avait des HP supplémentaires de la xpipe et de l’étape 2, les pneus se sont rétrécis à chaque session et plus difficiles à maintenir le rythme à 1:40s.

Ajoutant à la blessure, mes chevilles de pédale morts cassé mi-session! Je soupçonne que le contreventement de la pédale morte l'a fait casser! La pédale elle-même est tombée de sa position et s'est logée sous ma pédale d'embrayage. Je n'ai pas pu le sortir de l'engrenage. Heureusement, j'ai pu ramener la voiture dans les stands pour l'enlever. Je suis content qu'il ne soit pas resté dans mes freins dans une zone critique !

Dans l'ensemble, c'était une journée solide et a maintenu la voiture près des temps au tour 1:40s. C’était agréable de sentir que mes chronos moyens diminuaient pas seulement le PB lui-même. Je crois qu'un temps de 1:39 sera possible avec des pneus neufs! J'ai rencontré des problèmes de micro GoPro encore une fois et mon tour PB a un audio statique. Je ne suis pas sûr de ce qui cause le problème, mais quelqu'un a mentionné que le DAC USB-C s'enregistre parfois incorrectement et provoque des problèmes micro. La solution de contournement consiste à retirer l'adaptateur USB-C et à le réinsérer lorsqu'il est allumé. Nous verrons si cela va résoudre le problème la prochaine fois !

Un peu de post maintenance

Laguna Seca est difficile sur les amortisseurs et provoque beaucoup de compression. Je soupçonne que mes amortisseurs étaient probablement trop mous car la voiture frottait encore fort sur les doublures d'aile. J'ai commandé de nouveaux garde-boue arrière et je vais commander les avants bientôt. Pour l’instant, j’ai pris des mesures de précaution pour protéger le tube de remplissage car il frottait au virage 6!

Nouveaux pneus pour les roues de piste
A l'origine je voulais Kumho V730 mais ils étaient en rupture de stock donc j'ai fini par commander RE71RS en 275/35/18. Je m'attends à une adhérence similaire à la RE71R originale, sinon plus. Enthousiasmé d'essayer ceux-ci!

Débâcle de Deadpedal
La pédale morte originale a des chevilles qui traversent le tapis et la mousse. À l'arrière, les chevilles sont fondues comme des rivets et évasées. Malheureusement, le numéro de pièce pour une installation après-vente est maintenant NLA (Non disponible). Tous ceux utilisés sur eBay souffrent des mêmes problèmes que les miens car les chevilles doivent être cassées pour être retirées du tapis. Les peals morts du marché secondaire ne semblent pas remplacer cette pédale morte, mais au lieu de cela, collez ou percez sur la pédale morte d'usine. Cette solution ne fonctionnerait pas pour mon scénario. La seule solution était de réparer ma pédale morte en quelque sorte. Mon père pensait qu'on pourrait le recoller avec des adhésifs Liquid Nails. Je me suis dit qu'on allait essayer, mais je n'ai pas encore testé la durabilité. J'espère que ça marchera !

Crampons
J'ai eu un débat interne sur la question de savoir si je devrais aller aux clous vis ou non, car il y a eu des rapports d'échecs tout le temps. En fin de compte, j'ai conclu que le plus gros problème était les lugnuts ayant une force de serrage insuffisante causée par la friction et le grippage. Pour lutter contre cela, j'ai commandé un ensemble de lugnuts Project Kics Iconix avec des colliers flottants. Cela devrait assurer la tranquillité d'esprit pour au moins une année d'utilisation avec ces goujons. L'avantage était que ces lugnuts avaient également une patte de verrouillage pour la rue. Heureux de rendre les roues interchangeables plus faciles à nouveau avec des entretoises de 5 mm!

Simpson Hybrid S
Actuellement, je suis en cours d'exécution harnais Schroth Quickfit pro et Stand 21 HNR pour la tête et le cou de sécurité. J'ai finalement acheté une Simpson Hybrid S. L'hybride est le seul dispositif d'appui-tête qui supporte l'utilisation d'une ceinture à trois points me permettant d'être passager dans n'importe quelle voiture avec protection. Il semble également avoir une protection latérale du coup de fouet qu'un HNR normal n'a pas. Je suis heureux d'ajouter ceci pour ma femme et moi. En écoutant un podcast de Ross Bentley, j'ai été frappé par le fait que nous devrions tous envisager de rendre aussi sûr que possible pour continuer à profiter de ce sport. Avoir une retenue de cou indépendante de la voiture semblait être la bonne chose à faire.

Je pense que c'est tout pour cette mise à jour ! La prochaine journée de piste prévue est en septembre à Laguna Seca et je m'attends à avoir du plaisir!

Que reste-t-il pour 2024 ?
Je ne suis pas sûr. J'ai encore 4.1 entraînement final, sous-cadres solides, rafraîchissement de refroidissement / mises à jour, BBS GT4 sans pneus à faire. Je veux des sièges mais il ne semble pas y avoir de siège qui vérifie toutes mes boîtes d'exigences. La plus proche est la Recaro Sport C, mais elle est lourde et la solution airbag n'est pas encore sortie.

Toujours là et toujours profiter de la voiture comme-est! La vie a été occupée depuis le déménagement en '25, et l'ajout d'un FL5 au garage m'a définitivement déplacé un peu. Aucun des plans 2024 n’a encore été abordé, mais l’objectif est maintenant de suivre les deux. Je vais commencer par le FL5 et ensuite déterminer la hiérarchie de la piste. L'un doit être le principal et l'autre la sauvegarde !

Je suis sûr que ce sera amusant de comparer le FL5 à l'E90 sur la piste, tant pour les temps au tour que pour le facteur plaisir. :party0030:
