Update 2: The Revain support I got is great for processing returns. I received my full refund as the error was not my fault. It is likely that the aluminum levers attached to the driver's side cover were not at the correct angle. According to the installation instructions, the levers should be at an angle of 89 degrees, but how does the average buyer check that? To be fair, the other 3 cases don't make any noise while driving. If you are considering this kit, make sure the case you receive is within specifications so that the support arms form an exact 89 degree angle. Otherwise it is possible that the cover will scratch the rim near the center position. Update 1: Downgrading my rating to 1 star, the seller only refunded me half of the original price, but the product was defective, especially the driver-side front mod is not working. doesn't have enough clearance for my rim, so the cover may touch the rim from time to time due to road conditions. Can't really fault this product, my 20" wheel has a very small gap in the middle where it can touch the inside edge of the cap even if the cap moves outwards a bit.
