The pizza pans are installed! I was afraid they might look goofy. But as luck would have it, they're almost the same color as the car. So they blend in nicely.
The pizza pans are attached to the trim rings with stainless steel nuts & bolts. The stainless hardware was more expensive, but shouldn't rust. I don't want rust stains all over my wheels.
Now I can acquire fuel economy data while working on the Bimmer.
