Autocross/Track Tire/Wheel combo for 335is Coupe
I'm looking for recommendations on a dedicated autocross and track wheel/tire combo for a 335is Coupe. Stock size is 225/40ZR18 on 18x8 ET:34 front, 255/35ZR18 on 18x8.5 ET:37 rear.
I want a square setup for maximum use of the tires (rotation, swapping side to side, etc.), 18" instead of 19" for the weight and cost difference, relatively lightweight wheels but durable enough for autocross/track use, and something that won't break the bank. The tires must be at least 140 treadwear for local class rules (BMW CCA Turbo Stock).
The two tires that seem mostly likely are the Hankook Ventus R-S3 and the Bridgestone Potenza RE-11 (I have these on my S2000 and love them!). However the RE-11s are about $100 more per tire.
I've been told that 18x8.5 wheels will fit in front and the suggested tire size would be 235/40ZR18 or 255/35ZR18. Both of these tires come in both of these sizes.
Style is of relatively low importance, but I'd pay $10 or so more per wheel to get one that looked better than another, all other things considered equal. I also like the look of gloss or matte black wheels, particularly on a 335is, but that's a minor consideration, and usually more costly I've discovered.
What are your recommendations and please correct me if I've made any incorrect assumptions so far.
