Try finding a brake caliper... I hope you went with the larger brakes. With the new IT rules you dont't get a weight brake for having the smaller brakes anymore. If I stuck with the Audi I would put the big brakes onfor that reason. AND its impossible to find the proper carrier for the caliper.

PS: the only reason Raymond didn't switch yet is because we have 16 wheels that fit the smaller bolt pattern, smaller wheel bearings, and smaller brakes.
