The base bracket is supposed to fit over the lip on the backing plate flange. Do not shim it out with washers....your caliper won't line up with the rotor. No one has mentioned this issue before. It looks like I may need to increase the diameter of the inside of the base bracket to allow more clearance for the powder coating. At this point, I would suggest reducing the diameter of the lip on the backing plate flange. This should be easiest done with a flat file, removing a little at a time until the base bracket fits. Then you can touch up the paint on the flange. The other option would be for me to send you another set of base brackets that have a larger inside diameter. Let me know, if you would rather go that route.
