J'ai passé beaucoup de temps à magasiner et à essayer de décider quel kit acheter pour ma M3. Un jour, j'ai appelé Stoptech et j'ai parlé à Howard. Prochaine chose que vous savez, j'ai prévu un rendez-vous mardi dernier pour avoir le kit installé.

Je suis arrivé à l'usine de Compton où ils ont un énorme bâtiment et plusieurs CNCs et d'autres équipements de fabrication. Ils font leurs propres trucs, ces rumeurs à leur sujet en utilisant les étriers de quelqu'un d'autre sont incorrectes. Ils OEM beaucoup de choses, ils font les kits pour un grand nombre de ces entreprises du marché secondaire (dont je ne peux pas mentionner le nom mais nous tous BMW savons qui ils sont). J'ai été surpris de savoir ce qu'ils sont en train de devenir. Ils ont même leur propre dyno où ils soulignent les produits à faire des tests pré-TUV avant de l'envoyer en Allemagne. C'était cool de voir cette machine partir. :)

Stoptech avait déjà effectué des mesures de la E92 M3 en Europe. Ma voiture serait la première voiture sur laquelle le kit serait installé. Une très bonne chose à propos de Stoptech est qu'ils ont une plus large gamme de combinaisons de rotors que les autres sociétés. Par exemple, leurs 6 étriers de piston ont des combinaisons plus différentes de tailles de piston afin qu'ils puissent personnaliser l'étrier à l'application plus que les autres sociétés.

Ma voiture a été conduite et testée par les ingénieurs, et c’est ce qu’ils ont trouvé. 380x35 rotor avant, 355x32 rotors à l'arrière. ST60 6 étriers de piston pour l'avant, ST40 4 étriers de piston pour l'arrière. PFC1038 pads pour l'avant, Axxis ULT pads arrière. Les tampons sont des tampons de rue haute performance qui minimisent également la poussière. J'ai demandé l'option de forage croisé sur les rotors (ils ne se fissureront pas car Stoptech a éliminé cela en utilisant un motif spécial), des chapeaux noirs, des étriers noirs et des rotors revêtus de zinc.

Le poids est le suivant :

Avant
380x35 disque DRILLÉ + 37.160.D613 (chapeau) + matériel ~ 22.01 lbs
ST60 avec pads et support ~ 13.11 lbs

Arrière
355x32 DRILLED disc + 37.160.7425(chapeau + matériel ~ 19.33 lbs
ST40 avec pads et support ~ 11,145 lbs

La voiture n'a plus cette forte "amplification" initiale comme l'appelle leur directeur de l'ingénierie Steve. Cette morsure artificiellement forte au début a disparu. La pédale semble plus naturelle et se trouve juste un peu plus haut. Je ne pourrais pas être plus heureux. Ils ont câblé les plaquettes de frein pour moi. La voiture se sent plus rapide car il y a un bon gain de poids.

Voici donc à quoi tout ressemble et vous pouvez voir la voiture au Spocom dimanche sur le stand KW. :) Un grand merci à Howard et Steve chez Stoptech. Désolé, la voiture est un peu sale.

Nice pics félicitations. Avaient-ils déjà des prix ?
Joli, ça a l'air bien. Au fait, nous avons déjà eu ce « débat ». Vous ne pouvez pas sentir 20 lb de poids sur une voiture avec ~ 400 ch et ~ 3700 lb, même si elle tourne. Last but not least - prix s'il vous plaît!

Je vais utiliser une hypothèse éclairée ici et dire configuré comme je l'ai choisi avec rotors forés et revêtement de zinc un peu moins de 6200 $. Appelez Stoptech si vous êtes intéressé.

Ma M3 sera aussi au SpoCom, sur le stand Eibach.

On se voit. :)

très très très agréable :D

I'm going to use an educated guess here and say configured as I chose with drilled rotors and zinc coating just under $6200. Definitely give Stoptech a call if you are interested.
Stoptech or Brembo this $6-7k brake upgrade is just a bit absurd to me on the price side. Such a miniscule performance benefit to price ratio. If it cost $2k I'd jump on it in a heartbeat but at these prices, I'll just "suffer" with the "OK" performance of stock and add some cheap BMW track pads as required for track work.

Car still looks killer, JMHO above.
I've always thought the Stoptech logos to be very distracting.

Otherwise, they look nice and I bet work well, hopefully they offer their kits w/o a logo.
Those are beautiful, absolutely gorgeous setup with the Vorsteiner wheels.

There is one thing that needs to be pointed out with this list that the Stoptech caliper weights listed above include the pads and bracket. I know the weights that OC Kid provided were without the pads but I don't know if the bracket was included. Overall, I think the weight savings is about equal, maybe slight edge to Stoptech because the pads for the Brembos are surely more than 2 pounds, but the difference is trivial. Stoptech uses a smaller rotor in the back and both rotors are thicker overall.

Brembo 380x34 (F) 380x28 (R)

I had the Stoptech BBK on my 97 M3. It was a wonderful upgrade. I loved the Stoptechs.

As for the logo, I also did not like it. Being as the caliper is powdercoated, and the logo is painted on, all I had to do was take a rag and a bit of carb cleaner and wipe off the logos! Then I had nice red calipers on there with no BIG ASS logo on them!

If I go BBK with the new M, I will almost certainly go with StopTech. Wonderful company and product!

+1, I couldn't agree more Swamp.

Maybe, if I got lucky and found a wrecked M3 that had Brembos and could buy them for pennies on the dollar, then I would go for it. But if I thought that was realistic, I would play the lottery.
The stoptechs look fantastic!!

Have you driven aggressively on these yet? How's the fade?
It will be interesting to see a comparison test between the BBK kits and the stock brakes.... I think the standard 60-70-80 to zero test only once....there won't be much of a difference....only on the track after repeated hard braking will the BBK's start to show improvement over the stock brakes...but for a street car....its not worth it.... but the BBK's sure look better!

No I have not. I haven't had much time with the car since the brakes were installed but you can expect that this system performs as the other Stoptech systems do with the ST60 and ST40 setup which is excellent. The most aggressive braking performed was during the bedding process and fade was minimal. I have to get some 19" wheels for the track, these 25 series tires are like rubber bands....

...actually my measurements included pads and brackets. Your car is looking great badfish, keep up the good work! :thumbsup:

Thanks OC Kid. I was just going by this thread here might want to have him update the incorrect information. Regardless, 1 pounds here 2 pounds there is trivial...
Brembo F caliper assemb: OC reports 13.0 lbs without pads
Brembo F disc assemb: OC reports 24.8 lbs.
Brembo R caliper assemb: OC reports 9.6 lbs without pads
Brembo R disc assemb: OC reports 17.0 lbs.

Ohhh...I see lucid has not updated that post. I did mention it here in the thread...nonetheless, thanks for pointing that out. :thumbsup: See you on the streets.

lucid: Can you fix? :D
Updating this information since I re-weighed the stock brakes.

Does Brembo have an M3 specific BBK? Because the last time I phoned them about a month ago, they told me they do not have it. :( sorry if this has been asked or mentioned before!

Cheers!

Btw, the Stoptech brakes look sweet on your ride!
