BimmerSpinner BMW stock alloys

I bought a pack of four BimmerSpinners from www.bimmerspinner.co.uk with some hesitancy. They looked good, but I wasn't convinced about the technology. As it turns out, that's incredibly simple, and that's the genius of it. These are removable BMW-badged centre caps for BMW OEM alloy wheels. They stay facing the right way up THE WHOLE TIME! Even when you're doing ahem-ty-odd on the motorway (a friend tracked me in his car, and said the effect was incredible). Plus when the car's stationary all the wheels are uniform. It's pretty special! Their website has a video which demonstrates better than I can describe it!
