You probably know already that Avid sells these or you can simply use metric washers and stack as needed. Another tip, if you have a standard sized rotor you can get an adapter that extends the caliper mount either 20mm or 40mm to allow the use of a 203mm rotor which really adds stopping power.
yeah i'm planning on eventually getting a 203mm disc someday. had a few washers laying around so i tossed one on each bolt and it spaced it perfectly.
185 + bb7 = amazing stopping power! can't wait to run a 203 front and 160 back.
