295/35/18 on 9.5" wheel

GSS138

I have a stock suspension and sport brakes, I didn't mention that they are 18" wheels-track only. I have no spacers, just hub centric rings.

I am good with tires, I know very little about wheels besides their dimensions and how much they weigh. If you want to know more private message Mike at corner 3 garage or if mike sees this post maybe he can comment. Mike is the one running the extreme speed promo in these forums that is endlessly bumped. :P

He is the one that did my setup so he can answer better than I can.

But yeah I have stock suspension, 18" x10.5" RPF1's, Hankook rs3's 285 square, sport brakes, no spacers and they work fine. Martin82 on these forums whom I track with once a month runs I think an identical setup and he has 1 way coliovers and cambers-not sure if he uses spacers or not though.

the front 370 suspension does have alot of camber gain under load, but when i test fit my rear 18x10.5 et15 with 285/35/18 tires even with -3.2, i didnt feel it would fit without "self clearencing" under load LOL

I feel the key factor here is stock ride height.

Martin is on Enkei NT03 with 18x10.5 et30, no spacer front, and spacer rear (20mm). from my testing and research, et28(which i run) to et30 (what martin and what the Robispec 370 used to run) for 18x10.5 is ideal, since it pretty much takes up all the inside space it can before hitting the knuckle arm. I feel if you end up getting coilovers and as your pace gets faster, you will start to have rubbing issues with the et15 10.5s

Well turn 6 at Big Willow has put me in Dukes of Hazard mode before but only once or twice per day usually

and just to add some tireporn:

just saying at sotck ride height and 18s you prolly have a long way for the suspension to travel before even getting close to body work. and you might also be hitting bump stop before you even get to the point of rubbing

Well I'll take your word for it because I don't even know enough about wheels and suspension yet to totally understand what you just said. Care to elaborate on what you just said? .

BTW been watching your videos to learn buttonwillow, thanks for making those. I will be there Saturday with GF if you are there and see my car come say hi!

What i was trying to say is, since your ride height is stock, its higher for example to mine, so the wheel/tire/suspension would have a longer distance to travel before coming in contact to body work then on my car which is lower(but by no mean "low"). Also, since the length of the shock body is longer then aftermarket coilover shock bodies, under compression load, you'll bottom out( hit bump stop) with your wheel/tire further from the body work then if you had a aftermarket coilover with shorter shock bodies. This is my theory as to why you are not rubbing with 18x10.5 et15 285/35/18 up front.

Any questions you have from watching the vids? have you been there before?
i wont be there saturday, only Sunday for the time attack, ill be driving the Black JDM Civic Type R i drove at Willow springs

I have not done Button Willow yet so first time Saturday, we have the Nissan competition that day. Martin's and my car are parked next to each other up at corner 3 right now lol, his rear suspension was a mess when I dropped mine off last Saturday but I am sure Steve got it figured out this week.

I have contemplated staying on Sunday for a few sessions if I can keep the GF entertained long enough. It's a long drive for just one day. If I stay there I'll look for you, otherwise have fun and be safe.

No questions probably until I get a feel for the track but definitely have watched your video about 20 times already to try to memorize the turns!
