It's your call. Either cut the rotors down another .050" or get out the dremel. I wouldn't mess with the mounting holes.

Took off .030 which reduced the diameter by 1/16. Taking another .050 would reduce the diameter by another ..... well that amount is too much.
I have another set of brackets to play with

dropped them off at a "real machine shop"

owned by my friend. Either adjust the caliper holes or make a new bracket that works.
Richard at Arraut Motorsports is a nice guy but the product is sloppy. As my machine shop friend says... "what kinda crap are you bringing me now?"

told him I still have the rear brackets to go.....
