Up for sale I have 2 sets of RS Technik Wheel spacers, perfect to make the wheels on your M3 sit flush with the fender.
These spacers are only 2 months old and experienced about 3,500 miles of driving. I never experienced any "shakiness" or "wobbling" when using this set up.
Forum vendors sell these new for $115 each + shipping
I am looking to get $160 shipped for both sets
