I am looking to roll the rear fenders on my 2000 323i .I just bought a set of 4 m3 wheels/tires and the rear ones are 255/40/18 but they rub if somebody sits on the back seat. It seems like the only options are to roll the fenders or buy new tires(255/35/18). I would like to go for rolling the fenders.Please let me know if you know somebody in Toronto who can do it . Thank you
