Most dust caps have a little flange that fits up against the rotor. That kieeps the cap from going to deep into the rotor and rubbing against the spindle. I took the dust cap for my son's truck and put them upside down on a flat stell surface and put a socket into the cap and flattened the rounded curve on them. I made them fit closer to the spindle and still cloear the end, so that they could rotate and not rub a hole in the cap. I also took the chrome pastic cap for the boss wheels and groud a little off of the tabs that fit intl the wheel, so that there was clearance between the plastic cap fabs and the edge of the dust cap and rotor end. You want to leave the hooked edge of the tab, so that it clips onto the wheel.
