18" VS. 19"
Gents, I've searching the threads on this issue but would appreciate your input on rim sizes. What I've determined so far:
19 inch is better looking but heavier thus hurting performance with unsprung weight?
19's ride harder but offer a flatter surface for grip?
Will 18's accommodate big brake upgrade kits?
Having said this I think as long as the 18's will fit brake upgrades it's the better rim for the Z4M?
Is the 18'x9.5 rim the best choice? I'm think 255's upfront and 285's rear.
Thank you for your advice.
