old school hpi guys help me out!
the pro4 has narrow clamping hubs to which you add 0.5 and 1.0mm shim. i know that hpi made the same clamping hubs but in a widht that was wider, specifically the same thickness as the thin hub with 1.5mm of shim !!
i saw these on someones car and i measured them.
anyone know the part number? or can venture a guess?
i cant seem to find it out
