And is this something KMP did based on a config you spec’d or put together but someone else? The clock spring is the headache - can’t just remove it. I know KMP does have some options to move stuff to the wheel though.

This isn’t KMP, just generic OMP wheel, carbon plate, buttons from race spec, and Krontech QR with the connector option.

sweet. any chance you'd be willing to show the wang mount -> trunk/fender interface? i'm going to be trying to fab something up for the 72" alu wing i had fall in my lap.

Since I dont have an oem trunk I cant really show the clearance for that. My fiberglass skin trunk clears the mounts.

Not particularly hard. Just wires, switches, and rubber boots. Feeding into a Krontech QR with MS connector inside.

You don’t have to remove the clock spring, I used this on a streetable car for a while.

Assigning buttons depends on the button. I followed the directions from a KMP wheel someone shared with me. Checked and I must’ve deleted them. I can dig deeper if serious.

i'm not serious yet, but i'll have questions later. i just need to get my car running again with the parts i have on hand before i start messing with fringe details. i really like the style of that wheel though.

I assume these are directions you're talking about? Quick search and I found this thread. Thanks for sharing.

I'm working on putting together a wheel with the KMP QR with the MS connector, paddles, etc. Did you retain the clock spring or is it possible to get rid of that whole assembly?

Yes! Thank you for finding

Realized there was a question in there. No i retained the clock spring before the current build journey. Now the whole stalk is gone as i needed Woodward column.

Why do you want to get rid of it?

Just for simplicity. Once the lights, wipers, etc are in a button housing on the wheel I don't see a useful reason to retain it. Does anything have to be coded out to remove it?

You’ll need the whole stalk to configure the aforementioned functions to buttons per that KPM instruction guide.

But more importantly, what’s your plan for steering position sensor if you remove the clock spring? Believe that will impact ABS, DSC, and ECU functions. There are sensor options for going direct to standalone ECU, or a dash. But not sure what’s possible to communicate with stock ECU.

anyone ever need an adjustable endlink shorter than 11"?

have you guys ever welded aluminum suspension parts?

my camber arm has got a broken tab.

i know you live in BR so it's a bit harder for you to get used parts, but if you need help getting it "forwarded" it to you let us know...

but yeah you totally can weld it until you find a good replacement.

in fact JRZ had issues with the older tabs on their coilovers that snap off and they just get welded back on lol.

for today, that's the info I'd like to have.

thanks a lot for offering help. unfortunately br customs have restricted things lately, and I had a couple of parts (brand new!) denied and returned from Latvia/Lithuania due to allegedly "missing data" on the label. You can't argue with them, you say the data is on the label, and they say it's not, and bye bye parts.

that doesn't happen if you pay for courier companies (fedex, dhl, ups), but costs wouldn't be worth it.

shipping used parts would be even more risky.

Ahh alright well that settles that. Didn't even think about the steering angle sensor. I'll table that one and will keep picking through the wiring thinning thread to see what else can be pulled out of this thing before the cage work.
I've seen martyn at project rouge mentioned a few times for sending harnesses out to but can't find the profile, website, etc. Anyone know if they're still around?

He’s on the forum, but dm me and I’ll send you his WhatsApp. He did my harness. There are definitely others more than qualified if you’re in SoCal.

Anyone going to Laguna 2/28 (GGLC) or Thunderhill East 3/15-3/16 (HoD)?

On another note, does anyone have thoughts on whether it makes more sense to try more new tracks or do more days at tracks I'm getting more familiarized with? My first HPDE was last March and will be at 9 after these upcoming events. Tempted to try the new Buttonwillow Circuit track, but not sure if it makes more sense to stick to the tracks I know (Laguna, THill East) instead of branching out further.

Question's because there's a weekend in May that would work well with my schedule - would be nice to get a last event in before it gets too hot to be outside in the middle of nowhere. Inversely, I can throw the track fees at a Thunderhill event later in the year once things cool down a little.

Definitely want to make it a point of making the trip to BW 13CW (not sure when), Sonoma (definitely planning to try this year since it's the closest to me), and THill West and 5 Mile... just not sure when though. I'd want to prioritize becoming a better driver, so even if they're events I want to try, at what point should I switch from "sticking to the familiar tracks"?

Although this was 39 years ago, I found it easier to learn/advance by running on multiple tracks because you are dealing with more corners and braking zones which require different cornering and braking techniques. I don’t think it would hurt your learning curve in anyway. Spending 100% of your time on one track makes you an expert at that track with its corners and braking zones but that’s all you’ve experienced. IMO, shaking things up with different tracks helps to prevent developing bad habits and/or getting stuck on an advancing learning plateau. At least two or three different tracks are enough at your current level of track experience. By doing this, I found it a lot easier to learn a new track. VIR was closed when I started tracking but I was able to learn the full course in an advanced/instructor group after two sessions (not saying I didn’t still have things to learn but I was within ~3 sec of competitively fast e46 M3 lap times). I doubt this would have happened if I had spent 100% of my time at Summit Point main; however, ~75-80% of my track time was on Summit Point main because it’s only ~1 hour away from me.

I firmly believe that every driver should have a home track they frequent, for a variety of reasons:

• Track Familiarity – Knowing the track layout by memory allows you to refine your driving by focusing on technique. This builds confidence and consistency.
  
• Controlled Testing Environment – Having a familiar circuit lets you experiment with new techniques comfortably. Whether it's different braking styles, pedal control, steering inputs, or testing new suspension setups, you’re working from a baseline you already know.
  
• Growth & Improvement – Chasing your fastest theoretical time is a great motivator (for me at least). Constantly improving at a known track pushes your skills forward and helps develop a deeper understanding of your driving.

There are probably more reasons to have a main track, but these three alone make my reason..

For me, that track is Buttonwillow CW13. I know it well, and I’m essentially racing against my own ghost (data logging). I also feel comfortable enough to push the limits with a higher margin for risk compared to a place like Streets of Willow (where I’m also comfortable but a bit more reserved). On the other hand, I wouldn’t test new things at Chuckwalla, even though it's arguably a better track for experimentation due to its safer runoffs. I just don't know that track well enough, to have that baseline time.

Of course, there are downsides to sticking to one track, but once you’re confident at your home track, driving stress-free at other tracks becomes much easier—it’s all about taking what you’ve learned with you.

ok guys, couple hypotheticals... has anyone ever driven an e92 with no power steering on track? my first car didn't have power steering and i didn't have a problem with it, but i certainly wasn't tracking my '86 toyota.
garagistic makes a power steering rack blockoff plate, but i've never heard of anyone using it on these cars. seems like more of an e30/e36 thing because they are a lot less weight.

all the wiring is back in my car and just have to connect a few things like speed sensors. i'll be running alex miller's cup car kit soon.
another cool kit i found is this electric assisted steering... too many "unknowns" to know if it is a good fit for our application, but interesting to look at.

Thanks for the perspectives on these! Personally, I did find that I improved a lot after trying both Laguna and Thunderhill. I do think Sonoma is one more that I will try this year just due to how close I am to it, but we'll see when that is.

I agree that different tracks offer a differentiated learning approach. Some of the corners in Laguna are taken a bit differently from those at Thunderhill (esp gaining camber during apex and what to look out for that), and I think my driving improves from that understanding of *why* they are different. I still live with a healthy fear of trying tracks for the first time moving forward, but we'll see how I fare down the line.

Finding a home track is something I'll.... explore down the line. I thought it would be Thunderhill, but it's a decently far trek. 13CW/Circuit are also equally as far, so I imagine the home track will be Laguna or Sonoma since they're <2h drive away. Laguna comes with sound limits and higher cost, and Sonoma comes with walls... so we'll see :P I am absolutely loving Laguna over the 4 days I've gone since last Nov, and I'm excited to revisit Thunderhill in 2 weeks though.

Over 1 year in the making, I personally built my own Spec E9X (minus the cage) and competed in my first race this past weekend.

I completed Comp School last year with a street car and didn't participate in any races that weekend. This was my first ever race, I completed 4 races this past weekend which earned me my full competition license and will no longer be a rookie for the next weekend I do in April. Still a lot to learn and work on, but I'm ready to put in the work.

First milestone was on Friday, my car passed Tech without issue.
It's been a journey but it was a proud moment, I focused on staying out of trouble and completing the races. My car preformed well without a hiccup, it did have a stored code for the exhaust vanos mechanism, I swapped the solenoids and it didn't come back. So hopefully it's good, but I plan to put new solenoids in for the next race.

Here is a video some GoPro in car footage with AiM data overlays.
