For autox, track days, time trials, or road racing, what type of suspension and wheel/tire setups are you guys running?

I'm trying to get an idea of where to go exactly with my FC.

 

Im using Tein RE coilovers. And Yokohama A048R. This is a good setup. The coilovers are pretty stiff. But they can still be used on the street. But it does not like hard bumps.

For racing tiers make sure u have a decent sidewall. Not to low. Wich will make the car sensetive.

My setup is for a FD. But what is most important is the setup of the rest. Camber, Toe and so on. If u don't get it right, the car will not handle they way u wan't it to.

Mine is understeer, understeer, understeer atm. Wich is setup and nothing else then setup.

Well, I inherited the setup from the previous owner, but I'm running the Ground Control coil overs, with 400#/225# springs (f/r) and KYB-AGX shocks/struts. RB swaybar on the front, none on the rear. Seems to work well enough for me right now. Definitely a good bang-for-the-buck setup, but you do need to watch clearance on the inside of the tire to the strut collar.

This is for a track only car.

Crispy runs a similar setup and has a good writeup at:

Hope this helps,

I'm running Tanabe Sustec Pro S/S coilovers, and have been for many years. I have the first set to ever come to the U.S., so have put lots of (maybe 50k) miles on the setup. Absolutely love them, they feel amazing on a road course.

For rims, you may want to consider running stock FD wheels. I think you'll need spacers, but they are very light, and you can fit a 245mm tire at each corner.

 

I'm running 400# F 275# R Koni yellows all around. All delrin bushings, adjustable camber links in the arms and on the subframe on my FC. It is gutted and I was running 225 50 15's on all corners until recently when I had on-power traction issues and swapped to 275 40 17 in the rear. I have yet to test the car, but I'm hoping I can put the power down. I'm currently set for 340 hp at the wheels at 10 lbs of boost. The car is way fun.

I'm N/A, so I don't think I'll have on-power traction issues. But is 225 wide enough otherwise? My current racing experience is that of autocrossing a 3640 lb (race weight) AWD car on 225/45/17 DOT legal R-comps. 225 is definitely not wide enough in that car.

 

225 should be fine for stockish power level FC's. The AWD car you cite above is 30% heavier than you.

 

HKS Hipermax D' drift setup, with setting them harder they are usable at road racing track as well

 

Yeah, I figured that a 800-900lb weight difference would be pretty significant. What about rim size? 15" with low profile tires would be great for acceleration, but does it make the gears too short?

 

Well the road racers in SCCA ITS and E-Prod with FC's typically run 5.12:1 diffs with the shortest allowable 5th gear, and only on the fastest of tracks do they run out of gearing. So on a stock rear end, or even on a 4.3:1 it'll be fine. The lower profile 15's don't change the gearing enough to cause problems with top speed, unless you've got a lot of road, or lots of power.
