Just bought some new rst replica alloy wheels for the old girl. Changed the rear wheel no problems, then came to the front to find there was a strange sort of protective cage thingy, which also seems to be attached (or rusted) to the disc. When the screw on this was removed the entire disc becomes loose, very weird system. Anyway it's stopping the alloys from fitting. Can I get rid of these eyesores? They make alloys look like hub caps!
