Roll yer own bigger brakes (maybe)

A quick update and maybe you'll see something you didn't know. I picked up a 12" X 24" X 1\2" thick steel plate ($36) to fabricate the caliper mounting brackets. Made a cardboard template, then drew the outline on the steel plate. Dropped off the plate, template and spindles at the machinist. He'll get back to me fairly soon. In the meantime, my curiosity got the best of me about how this setup would work in other sized wheels. I know it works in 17" and 18" wheels, but what about 15" wheels? It so happens I have a set of 15" Mopar Cop Steelies sitting in the rafters so I got one down to check for a fit. Guess what? It sorta fits. Sorta? Well, when the Dakota hub, Crown Vic rotor and Lexus caliper are placed in the Mopar 15" wheel, the tapered portion of the rim fouls the caliper. BUT, if you run a 1\2" or 3\4" spacer, you've got all the clearance you'd need. So, that's the answer to the question nobody asked.
