I have heard other people talk about using the Modifiers wheels, but never seen pics. I picked up the new deluxe kit today which comes with 4 sets of wheels. These are a little harder to mod than most wheels, but they are really nice. They are actually metal, so they have a real alloy look to them. Also, you can switch out the wheels easily by pulling the wheel and tire right off the hubs and switching. There is a piece of rubber on the hub that holds them on and keeps them from slipping. You do have to put a little glue between the tire and wheel to keep the tire from slipping. It also comes with a cool little stand that looks like a minature wheel shop and has a storage built in.
