In Reply to: NE1 racing with 245/40-17 ALL AROUND? posted by Texas ///M3 on January 30, 2001 at 19:14:58:
I am seriously considering this setup for racing. It will allow me to rotate tires amongst the racing wheels (most likely BBS RCs or SSR GT1s) as well interchange my stock wheels with the racing wheels if I want to move back to Stock Class.
I saw a few guys in our club with 245/40's on 8.5 or even 9's all around. Its the way to go for handling and braking at the track. You will need 40 to 45mm offset, and maybe spacers in the front of 10 to 15mm. Alot depends on the type of track tire you run i.e. tire diameter and section width. BFG R1's have very squared shoulders and run tall, so they rub easy.
