If I read the SCCA Solo II rules correctly, I can run in B Street (formerly B Stock) with my AP-1 and legally use 17 inch wheels. Any comment on this premise?

Will AP-2 stock wheels fit my AP-1 w/o modification and all reasonable clearance with an unmodified suspension and stock size tires installed? It appears they will, but as I am a new owner & before I drop $$$ I seek your collective guidance.

Going one step further, how does the CR rear tire size work on an AP-2 wheel mounted on an AP-1?

Thanks in advance for any response.

My car is an AP1 with AP2 wheels and they fit fine though I would rather have the 16" wheels

all OEM AP1/AP2/CR rims and tire sizes are compatible. I run AP2 rims on my '03.

good luck this season.

For SCCA competition, you are not technically, within the rules, allowed to run ap2 wheels. That being said, most local organizations will be fairly lenient on that ruling. The rule technically states that you can go +/- 1' in diameter but cannot change width IIRC. There is also a minimal adjustment in offset allowed. I have not found a 17x6.5 inch wheel that fits on the front as 6.5" is a very narrow width. Running a 17" wheel may allow you a wider tire option in the rear but the real limiting factor is our lack of width up front. Talk to your organization and check but if you are not in national events, I think you should be fine.

16" and 17" OEM wheel+tire sets have the same diameter and will fit just fine. The 16" tires are higher profile than the 17". 255mm rears fit fine on the OEM 17" wheels on my 2006 car and I see no reason they won't work on earlier cars from the time I've been under both generations. It appears fronts can go as wide as 225mm without buggering the body work from posts here but I've retained 215mm on the front for normal street and back road driving. These cars tend to oversteer especially if the throttle is lifted in a corner and I think this combination will help negate this. (If my recollection on the front is wrong I'm sure I'll be corrected quickly! )
