ok guys, i'll soon be buying new wheels for my Z. i dont kno if i should go for 18s all around or 19s all around. i even thought of 18s in the front and 19s in the rear...people tell me 19s take away from performance. please give me some input on what size i should select
*is the any benefit in having 18s in the front and 19s in the rear like Vettes have?
