Taken from the Brake Guide:
"Caliper bolts straight on. Disc requires 3 holes drilling (5x100pcd compared to 4x100). Disc requires machining down to 300mm for wheels of 16" or smaller."
What's the views on the best wheel size to use with these. Machine down and go with a 16" or leave as they are and use 17". Is there arch rubbing issues with 17's or anything else I should be aware of?
