James - Have you any idea what sized spacers you used?
weegaz22 - Yeah its fouling the rear of the spokes, as james said about the offset and as i suspected it maybe an offset thing. Not tried it with the discs on yet, cos i aint got'em

Spacing on the calliper bolts??

Its defo not fouling the balencing weights and as for having the callipers upside down, i could well do mate - I'm still not 100% sure this is worth all thsi hassle
