track wheels and tires

i can answer this one. it's all about the $$$. light weight wheels cost more than heavier ones. sticky tires don't cost much more, but they will wear out faster, so the $$/heat cycle is higher. my formula was: buy the strongest, lighest wheel that i could afford (SSR type C-RS). start out w/ moderately priced, relatively long lasting r-comps (RA-1's). if the manufacturer recommends shaving a particular tire for track use, do it. contrary to intuitive thought, they will last longer and perform better. as the disease gets to more advanced stages.....use your original wheels for wet/intermediate tires, order two sets of custom racing wheels so that you can properly heat cycle your new slicks, get the stickiest and widest tire that you can stuff under the car to take advantage of the bbk that you added and all of the suspension mods. ask me how i know.....
size is a function of many factors. do you need (or will you need) clearance for a bbk? smaller diameter wheels are generally lighter. someone elses stock takeoffs might be a good starting point (and can be found relatively cheap) adding camber increases the max size that will fit by tucking the tire inside the wheel well. on a stock setup, a 215 tire is about as wide as you can go. that said, i can stuff a 225/40/17 Hoosier R6 under mine and will be trying a 235/620/17 Hankook F200. i am confident that it will work. available sizes are more limited w/ r-comps. get them well ahead of anticipated use and figure out what spacers, grinding, etc. may be required.

Go smaller if you can. Smaller is lighter and cheaper. I have the Wilwood 11.75 BBK and I still use 15"s for the track. Team Dynamics Pro Race 1, 15x7, et+35. Then I use Toyo RA-1s in 225/45/15. The combo is light, cheap, and smaller than stock so the improved gearing makes the car faster.
