I've got a 323ci from 2000 with 225/50/16 pirellis on the BBS style 16" MVs.
I'm considering the 18inch 135Ms, or the 18" M3 alloys, which I reckon would sit on a pair of 255/35/18s at the back; 225/40s at the front.
1) From what i've heard, I wouldn't need to make any suspension mods, or do any "fender/arch rolling" to accommodate the 18 inch alloys. Is that right?
2) I need new tyres for the moment anyway and I've found a good deal on 225/45/16 tyres. From the factory it usually comes with 205/55/16s. Do you reckon these would fit OK or would the car ride too low on these?
Any advice appreciated.
