Hi all, I have a 2003 S4 with RS4 front brake conversion, the front wheels are fitted with 10mm spacers to clear the callipers, the rear wheels are standard fit with no spacers fitted. Do I need to fit spacers to the rear wheels, will it improve the feel/handling of the car at all? What size spacers do i need to fit, would you go with 10mm to match front or 15mm? Are the hubcentic spacers on Ebay any good? Seen some UK manufactured ones on there. Any advice or opinions on this would be appreciated, thanks.
