Hi folks as title i have a 3 door with 17 inch BBS rep they look so nice on the car but ive upgraded the brakes to E38 4 pots with focus rs discs 324mm. The problem is when fitting wheel the caliper is fouling the face of the wheel ive tried spacers but looks gash and still fouls anyway. the diamiter is fine. My question is what offset do you think i will need? i love the style of wheel and dont really want to put a different style on it. Cheers.
