E90 BMW suspension... lol
I have a 335d I'm running in SCCA Tuner 3. The irony? I'm running MCS DA remotes :-) The RX-8 had to go away for now (just moved). We'll come back to an RX when I'm not mid-build.
I am really looking to this weekend. It will be my first autocross in a few years. I registered for the first Washington DC event of the season and I can't wait. I am new to the area so I look forward to meeting the local crew. In the past my job has kept me from making more than half the events in a year, not this year. I should be able to make them all.
The car is way underpropped at the moment, but I want to drive it as is before I start changing things. It already has a Racing Beat intake and cat back. I will be looking for a wheel and tire combo, and coil overs shortly. Seems like at least a front sway will be needed as well.
I have read all the way through this thread and I really appreciate all the insight that has been shared. I will try to get the alignment checked and set to something reasonable in the next few days, but I live out in BFE so I am not sure I will be able to find a place that will align to supplied specs rather than "factory settings". Its okay if I don't find a place as this first weekend is just meant to be a baseline so I am not setting my expectation very high at all.
based on Team's advice I learned that the minimum caster setting gives you maximum camber. I've been running that way this season and like it
It was great meeting everyone. I had a blast and I am already looing forward to the next event.

After looking at the location of camber and caster adjustments that makes sense. How much camber are you able to get? Great to see the helmet cam. I had a first row seat for your smoking launches, set on kill from the word go....

i do my alignments in my garage so I'm not sure precise camber numbers but I appeared to get nearly 0.4 more degrees each side by swinging from max to min caster. My car might be faster with additional front camber but since it's a daily the max OEM allowances are pretty good compromise

I think this method is in my future. I am having no luck finding a place anywhere near my house that I would trust. I have a frozen camber bolt that will have to be sorted out before I do anything. I am going to take one more shot at getting it loose before I resort to cutting it out. Actually I have not checked all the adjustable bolts so I may have more than one.
@hufflepuff what do you use to get your car aligned? I have seen some plates that can help you set camber caster and toe, but it seems like I woudl need to buy or build some sort of stand for each wheel so the suspension can be loaded while making adjustments. My cousin recently sent me a link to an interesting product.
The add says that it will work for our bolt pattern. The price seems okay. I sent an email to ask if it would ever be back in stock. No answer yet.
17x9 RPF1's with 255/40 R17 Azeni's are on order. I know they are not the fastest thing out there but the Yoko's are backordered everywhere and I did want to wait and hope for the new RE-71rs. Not a lot of info out there for the new 71s and some of what is available points to them being more track (endurance) focused. I look forward to seeing how they turn out. I loved my last set of their predecessors on my NC and then Legacy GT spec.b.
Hawk HPS pads have been ordered and delivered. If I get motivated they will go on this weekend.
Last but not least I ordered a set of Bilnax coilovers from Shaftworks. I exchanded some emails with Jonathan and settled on 12/9k. Reading through this thread a few locals are already on a similar package. It came down to the Bilnax or Ohlins (which I had on my last 8). I loved the Ohlins but I was not totally happy with the spring rates. They were fine for every day driving and okay for canyons/mountain roads but seemed a little soft once I bolted my autocross wheel /tire combo. I didn't really have them for very long as I lost my car to a rear end collision a few months after installing the Ohlins.
Other than required maintenance this will probably the end of throwing parts at my new car. What I need more than anything else is seat time for now.

DIY Wheel Alignment It?s Easier Than You Think! | Speed Academy
two pieces of home depot metal conduit, fishing line, jack stands, spring clamps. it's not perfect, but i am not after perfection. i am after reasonable function. total cost was likely $20 or less since i have the jackstands. it is much easier to have the car up on rhino ramps or similar though. or else you probably need to jack up the car to reach the eccentrics.
honestly if you just ordered coilovers with those spring rates, you'll want a full corner balance anyway, which is done in conjunction with alignment. i have soft springs which are far less sensitive to create corner balance issues.
Does anyone think the proposed changes throughout the Street Prepared class will push folks to move their RX8 back to STX? Seems like BSP will be a tough class with some heavy hitters.
Hadn’t see those, which come to think about it I haven’t seen any Fastrack notice in forever. Did they quit emailing those notices out? I should just finish my car out straight to Street Mod then maybe.
Cut and paste from the (attached) fastrack news bulliten. SP portion starts on page 3.
The proposal reduces the total number of classes from 7 to 5 within the Street Prepared category, as follows:
ASP: Current SSP and ASP cars with some ASP cars moving to BSP or CSP
BSP: BSP with fast roadsters removed. RX-8 from DSP and BRZ/FR-S from CSP moved to BSP.
CSP: Current CSP cars with fastest BSP cars (Mazdaspeed Miata, ND Miata, S2000) moved to CSP
DSP: Current DSP with the RX-8 removed combined with current ESP
ESP: Current FSP
I am the first to admit that I am a novice when it comes to this subject, but I would think that the GT350, ZL1 Camaro, M3 and other high HP cars will be hard for the RX8 to keep up with. More so on longer open (Nat) type courses.
not sure what the difference in conditions were, but for the 2021 National Championship Steve O’Blene’s winning DSP RX8 time (109.028) beat BSP (109.530). They did run opposite courses on different days. So straight up on the same day/conditions it might not pan out the same, but both of Steve’s winning runs were faster that the fastest BSP runs on both courses.
Even David Colletti’s 2nd place combined time in DSP is lower than both BSP and ASP 2nd place times. The ASP winning combined time was 108.890, but again different courses on different days. Guess we’re lucky they didn’t suggest moving the RX8 to ASP.

Has anyone tried the new RE-71RS? My Kumho V730s are finally below the wear bars and the A052s are not in stock. i have quite a few events left this season and not much rubber. Thinking either 245 RT660 or 245 or 255 RE-71RS.
I haven't had the chance yet. We basically lost all of our sites this year so I'm not wearing out my RT660s like I'd planned. I might just get a fresh set for next year.
I have been scrolling a few threads and not really finding what I’m looking for so I hope the autocross community can help out.
I am wanting to run 265/35/18 tires. Max width allowed for STX. Any recommendations on tires and offsets that will work well. I don’t want a huge stretch or a muffin top. Would like to avoid having to do a crazy fender roll if possible.

Light weight rims a plus for sure.
Thanks in advance
Is there a reason you want to try this? Steve and I tried this and saw no benefit between 18x9 and 17x9 265 vs 255. The 265 package was heavier and no faster, plus more expensive.

the reasoning is to just max out the tire for STX. 265 17s are few and far between. Right now I’m running 245/40 18s
If there really is negligible difference I am not opposed to a 255 17 tire. Just figured if I’m building the car to STX specs might as well get as big a tire as I can
I skipped the last few events because I was waiting on parts to sort the suspension out (frozen camber bolt). I finally finished replacing the LCSs and hardware. I also received my new Coilovers in time do the install at the same time. Shaftworks single adjustable in 12k/9k. Unfortunately there are no more events close by this year, so I will have to travel a bit.
Set the ride height at 13 3/4" front 14" rear for now. I was able to settle the car on some race ramps before tightening everything down. I will be traveling for work over the next few weeks. Plan to get an alignment done when I get home. Should be all set for the next event near he end of the month. I still have a lot of learning to do, but I have more confidence in the car now.
