I run about -3 front negative camber and have maybe a quarter inch of clearance without rolling the fenders... that's also with a 285 hoosier series tire on the front, which runs more like a 295... so, what's the math? according to this calculator

you'll be an extra 8mm out... which is about 0.3 inches... I suspect if you run a 265 or at most 275 tire with -1.0 camber, you'll be fine
