We have tried numerous ways and we either rub the rear trailing arm or the track is wider than the fender. Personally I think the 205s are faster than the 225s anyway. Takes too much hp for those wider tires on the faster straights.
I dunno... I'd say most ITA CRX's I've seen through the years ran 225/50 14's. I ran (IIRC) 14x7 38mm offset TD Pro Race 1.2's all the way around. There was a very small (2mm?) spacer used at the rears to keep them off the RTA too much. They'd still polish the RTA some but nothing worth worrying about. They'd clear the rolled rear fenders without any problems...
