These are my track shoes, and they worked really well yesterday at Laguna. All I was trying to do was run the widest possible tires without rubbing. Since the R888's run a little bigger than non-R-compound tires, I went with 255s up front. I may have been able to get away with 265s, but wanted to play it safe. Maybe next time. The car tended to oversteer on the stock stagger/config, so my theory was that my combo would help balance it out. I was happy with it yesterday. YMMV.
As for the rears, there's no way that I could have done 295s without rubbing on this wheel offset. I can post fitment pics, but it looked like the 285s were going to rub the wheel well lip under full compression. I consider myself really really lucky that there wasn't any rubbing at all yesterday. This pic shows how little room there is left in the rear.
