Im having problems getting my wheels to clear my clio rear brake calipers, ive got 10mm spacers on but there still catching, other problem is that the wheels i bought have a 63.4mm bore and the clio hub is 60.1, I thought about hubcentrics but they only seem to be available in 15mmplus, my dad owns a factory that use cnc lathes so what i was wondering, would it be possible to manafacture a 12-13mm hubcentric spacer that bolts on to the 60.1 clio hub and that has a 63.4mm hub for the wheels to sit on? i dont have alot of knowledge on wheel spacers and how they work, i know we could make them easy 
If not any other ideas?
