I had been keeping my eyes peeled for a cheap set of wheels for the R32, that I could swap the winter tires onto and then put the summers on the factory wheels. I had a tough time finding anything that fit the bill, and for under my budget for used wheels I managed to score a set of brand new Alzors from ECS Tuning. They were on clearance, and I liked the look well enough (they're replicas of wheels found on the Audi S8). The quality is OK, though the center caps are pretty poor. I used Siemens tire pressure sensors and didn't have any trouble with them at all. You just need to keep in mind that the factory tire pressure is a lot higher than you might think - 42psi both front and back. Get it much below that and you'll get the TPMS warning light.

Here she is, with the summer wheels and after a fresh coat of wax:

After waxing it by hand, I know where all the little imperfections are. There are a few rust spots starting that I need to nip in the bud (the car is 6 years old, and from Maine, so I'm not too surprised), and the rear bumper has been repainted... the paint was very well done and I never would have noticed except I can see through a couple of scratches that the color underneath is deep blue pearl.
