The problem you have is wanting black wheels.! There are loads of white narrow bearing wheels, from associated, proline, schumacher etc..
Cutting wheels down, is ok and works fine. It was necessary until recently, for the new b5m etc with hex front wheels.. You just cut down adjcent to the inner wheel rib....this leaves one rib and the inner part of wheel to glue to.. With narrow front tyres, you don't need inserts..
