My Time Attack wheels are coming in late June. I've tracked shaved RA-1's on my oem wheels before. I know some of the "track-only" S's run 235/275 RA-1's w/ a boatload of negative camber.

My car is not track-only, but I do have an extra set of AP1 oem fronts. I was thinking of putting the 225's back on them and 255 on the CE28N rear wheels. This keeps the overall height fairly close. I then would leave the Toyos on the fronts all the time and only have to switch out the rears.

More importantly, however, is the impact in handling. If I weren't sc'd, the previous 225/245 on 16's would be plenty of tire for my skill level. I'm not sure that only a slightly wider footprint would be that advantageous either, save possibly the increased sidewall stiffness. I know other cars have varying wheel diameters, but I have no clue as to whether or not this will help in the S2000's case. If it were a great solution, I'm sure you all would already be doing it.

TIA,
Skip

 

I'm running NSX wheels as my track set -- 245/45/16 front and 275/40/17 rear. I haven't had any problems with different diameters yet. I only have one track day and a bunch of autocrosses on them, though.

 

It should work fine. A 225/255 split should keep the balance pretty well (maybe a little more push) than the 225/245 combo. I have been running 225/255 Victoracers with no issues for a while. What kind of wheels are you getting?

 

Sounds perfect, and the 16" tires should be cheaper. Rim diameter is irrelevant.

Thanks for the responses, gentlemen.

Bryan, I might have to look into some used NSX wheels. The larger footprint might help to keep me out of trouble, but not necessarily make me a better driver.

Pete, I ordered some Volk CE28N's(flat black w/ red ring) some time ago and sold the gold SF Challenges.

 

Hey Skip, are you staying staggered with your new set up? I'm about to order a set of 17x9 CE's for myself at all four corners. Sorry for the hi jacking.

As far as your actual question goes, the wheel diameters are fairly irrelevant as mentioned, but with 16's the front will have a taller side wall which can sometimes take away from steering feel, which isn't that important, but some drivers like a thin side wall up front for more feel while sacrificing a little braking performance.

 

17x9 will rub despite the +63 offset without flaring the fenders or not lowering the car. I looked at that option, but I think keeping some stagger suits me. That's how I learned to drive the car almost 4 yrs ago( ). Too old to change styles now.

 

I don't think there's any rubbing with 17x9 CE28 with 255's. Doesn't with either of my cars, and others' experience as far as I know is the same.

 

Guess I've been misinformed again. You're running 255 up front, huh? What size in the rear- 275?
