Hey why don't my starfish center caps fit my CS wheels??
really? mine fits perfectly. one possibility, your star fish cap isn't oem, or maybe for another model?
Do you have the 18" Challenge wheels, or the 19" Challenge Stradale wheels? Indeed the 19" CS wheels use the 340066 cap, while the 18" race wheels only seem to fit with wheel cap 188828.
Hahaha, ha, ahhhhh, wait that makes me sad Sure enough, the specs can vary ever so slightly. When I rolled my fenders this past weekend, I found the tool's hub holes and conical washers all needed to be ground out a little so the Ferrari bolts would fit through them. I guess it was Tuner focused Good thing was, Hill wheel spacers and stock 55mm bolts fit great and held firmly with no slop. I also love the fact that my OZ Superleggera IIIs are the same diameter as the Challenge race wheels Stock Spider center caps fit fine!
