ok having heard all the good stuff about going back to 15"BBS wheels, ive decided im going to loose my 17"alpina reps in favour of some 15s, but ive no idea what size/dimensions to go for?
Theres loads of wheel jargon that i dont get about offset etc...
so bearing in mind ive now got wilwood 4-pots on 280mm disks, what dimensions (width and all the other fun stuff) do i want for kick ass e30 handling? im going in with new suspension too, probably the H&R cup kit, so any help would be well recieved...
