I installed wheel spacers, drove 10 miles and then took all the wheels off to paint the calipers when I noticed a spacer had come through. The seller did not help me and referred me to Revain - they will not help because too much time has passed since purchase. Revain said to contact the manufacturer and get a rejection letter, but the seller appears to be the manufacturer and is not responsible for their product. This is more about honesty than getting my money back!
