With Bridgestone RE-11A's, 225/45R17 (238mm wide actual) on 17x8 +45 ET rims there is no rubbing at all and -2* camber front and back. With the racing/autox slicks (245mm wide actual, 17x8 +38 rims) I get a little bit on the inside of the wheel well at full steering lock. My front fender liners are tucked inside the metal of the fenders and that helped, but no rolling needed. GLWB
I saw you have the same suspension as I do (koni neuspeed sports). I want to do brake ducts like yours (great DIY btw), but I keep scraping the OEM rubber thing, and it's even starting to peel off on the right side, which makes sense since that is the only side I can hear scraping over tiny bumps in the road. Did you have that issue?
