cheers jahan, i've decided to go with 18's, im not 100% sure if my car has been lowered... it sits pretty low atm, and i have 18s atm, and they dont scrub much... but might with a car load... the 18's im running at the moment aren't low profile either, so when i get my new rims, im getting low profile with them, which may help as well.
Cheers for the help guys.
