cheers guys,im not one for cleaning wheels ,just use turtle wax alloy cleaner,spray on leave for 3 mins then jetwash off,,,always does the trick lol,i have had ultralites on my skylines (pic below)that were similar in design (although with a big dish),love the design of them
and no,no spacers,it happened once,only driven 3 miles since fitting them,maybe i heard something else,will see if it rubs today
