I know it's probably been thrashed a zillion times but I've grown weary of searching. I'm about to put new track shoes on my sport suspension stock '05 with 15X7, +28, 16X8, +34 Rota Slipstream rims, presently running 205/50-15 and 245/45-16 RA-1s. What is the consensus of size, primarily fronts, 205 OK? I see a number of you use 225s but I suspect that may be with mods, i.e. camber, etc, of which I have none. Then there's the decision of R888s, Hoosier R6s or? I'm running with NASA in TTC and am about 4 -5 secs adrift of a 944 and would really like to be giving him more of a challenge.
