This is an excellent and well-made full wheel spacer kit. They fit perfectly on the hub of my Audi S3 8V with no play or rattle. The holes align exactly with the wheels and the axle. A couple notes that may help someone deciding on purchasing or installing these: I have aftermarket APR flow formed wheels, 19”, and these fit just fine. APR includes a hub adapter insert to mate the wheel to the factory Audi hub, and that in turn mated up perfectly to these spacers. No issues at all. Also, if you have swapped out your factory brake rotors for two-piece drilled/slotted rotors as I have, these spacers are going to give your wheels a little bit more than a “flush mount”. The wheels/tires extend probably about 3-4mm beyond the wheel well in the front, and maybe 1-2mm in the rear. As a result I decided to purchase thinner 5mm spacers from Urotuning for the fronts, but left the rear’s as-is for the more aggressive look. Just keep this in mind that depending on your particular rotors, you may get a more or less aggressive look than you were expecting with these 12.5mm and 15mm spacers.
