Installed myself as it was extremely easy, no garage needed. Wheels are flush now.
Fast delivery, ordered black 15mm for the front and 20mm for the back, was happy to see the also sent out the correct wheel bolts for each spacer which I didnt think of, installed myself, just used the spare jack in the car and removed each wheel one by one, was very easy, take wheel of, fit in spacer, either on the wheel or the wheel hub, align the wheel nut screw holes and simply place wheel back on, Done.
