hallelujah! I didn't much like the idea of running 15s and standard brakes. Theyre badly underbraked just for spirited driving, but if I can run 17s that means I can easily move up to 324mm rotors which would be nice. Whats the rules on rim widths? I'm running 17x9 all round at the moment and I get the feeling that wouldn't be legal.
The turbo Ive got on the moment would probably suit a restrictor pretty well, just might need to find a 3.9 diff out of something.
hrmm might be back to building the car to IPRA regs... Thanks for the info :D
Edit: Just reading...17x9s are allowed for silvias but I can't for the life of me find a A032R or A048R in a 50 profile for 17s. Probably cheaper and easier for me to run 16x8 R32 GTR rims as opposed to the R33 GTR rims I currently run.
