Ive started autocrossing this year after a few years absence. I only ever did a handful of events before that so I'm FAR from a seasoned veteran. My car is a 94 R2 with a stock motor(51K miles), 99turbos in seq....guesstimating about 330-340HP at the wheels. Suspension mods consist of JIC FLT-A2 coilovers, Widefoot swaybar mounts, 93' 19mm sway bar, toe links and trailing arms. Wheels are 17X8F, 17X8.5R and 235/45, 255/40 Toyo T1-S street tires.

I'd like to get a separate pair of wheels and R-compound tires for autox and would like to see what other people are using here on their FDs. Would 18s be overkill for an FD with my power level???? Say a 245/35 F and a 285/30 R??? If not 18s, I was thinking of 245/40/17s all around. I have taken plus sizing into account and these are just alittle under the stock 225/50/16s diameter, which would seem more beneficial. I plan on getting a set of the Volk forged monoblock CE28s, which even in 18s will be lighter than the HRE 540s that are on the car now.

Oh, I'm also running -1.3 camber up front and -1.0 in the rear. Have some toe out in the front and toe in, in the rear...however I cant precisely remember how much. Car has also been cornerweighted. A former FD owner told me he liked the way his car handled at -2.3F and -1.9R with 1/16" toe out Front and 1/16" toe in Rear. That was on 17s as well.

Thanks for any suggestions/advice and or disclosing of your setup!

Cheers!

You have the stock brakes right? If so then run your stockers. Those stockers are strong and light, they weigh like 15 to 16 lbs and are 16x8.

Buy yourself four Kumho V710s, 245/45/16 and call it a day. The smaller the wheel the lighter the wheel. So get the smallest wheel that you can fit over the brakes. I think even 15s will fit over the stock brakes. I've seen 3rd gen front calipers on a 2nd gen with 15" BBS convertible wheels. So they will fit over 15s. I also don't believe in the stagger setup for racing unless you tuned the suspension (alignment and roll stiffness) to account for the increase foot in the back. Also with a stagger setup you can't rotate your R comps front to back or LF to RR and RF to LR. Rotating R comps increase their life incredibly.

If you want ultra fast setup for wheels and tires I think this is what you want:

15x8, not sure what FD offset is... +50mm?
The new Hoosier A6, P245/50ZR15... You will Need atleast 8 tires (2 sets) since they heat cycle to death quick...
A nice racing tire gauge with bleeder that can read between 0 to 50 psi(g).

Yes, I still have stock calipers...just aftermarket pads, fluids, and stainless lines. So you see no reason to go wider than 245, even with my power levels??? The Volk forged monoblock wheels in 17X8 are listed at 14.8lbs. Given the same tire diameter, you dont see it necessary to run a lower series 245-40-17 vs. a 245-45-16. I would save alot of money for sure by sticking with the 16s. I was actually looking at the Kumho V710s and the Hoosier A6s on tirerack.com. From their write-up, the V710s performance drops off after the 1st race, while the Hoosiers keep their grip and are lighter---but cant be driven to and from an event.

Thanks for your help

Cheers!

I guess if money is no object than sure a japanese ultra light weight wheel would be cool. But it looks like money could be better spent else where like SCCA SoloII school events. That will get you 5 seconds a run, versus the 0.04 seconds a nice light wheel would.
