has anyone here fit a 255 tire on a stock gt3 rs fender in the front with an 18 inch wheel.

do you guys think it will rub

 

I have 255/35-18 R6s on my 9" fronts and -2deg of camber.

 

fits w no problem

 

Same here.

 

I recently ordered a new set of 18" wheels, based on other guys recommendations I'll put on them Hoosiers: 255/35 and 325/30.
the fitment will be just right, Rims offset's are critical
For a regular GT3 these are:
9x18” y 12x18”
Offsets: Front: +51 Rear: +63 (to be used with OEM 5mm spacers).

 

If you want big fitment up front, talk to GMG about their Cup fenders. I'm doing 19x10 with 265's with them.

 

I run 255 and 335 R6s.
