Hi Chris,
I'm looking at some TE37's. 17x8 +33 front, 17x9 +40 on the rear. I have the standard R33 GTR wheels on it at the moment for track days. Trouble with them is that they're 9" wide and with anything more than about -1.5 to -2 degrees camber I have clearance issues on the front. They've been fine till now but I'm not going to slap semi's on them if I know I can't run more camber.
As for tyres.. not sure yet but I did have RE55's in mind. How much more life are you getting out of the tyres by rotating them? 1 or 2 tracks days?
