I think these are cool, but I worry about dissimilar metal issues with aluminum up against steel. You've see what your hub looks like when you pull your wheel away, granted the hub isn't painted and wheel cleaners can be aggressive. Aluminum + steel + water (and salt in my part of the world) adds up to accelerated corrosion. Maybe anodization or paint the interface? Maybe the paint on the body of the car is enough?
