How to Install 14 Inch Brakes on an A-Body (or B/E also)

This is a great thread. Just what I have been thinking about as far as modding a standard rotor. When I asked last, Dr Diff wasn't selling the hub separate from the kits.
I've got a damaged rotor to play with and a full set of 2000 BMW M5 front brakes that use a 345mm x 32mm (~13.6" x 1.25") rotor. They are single piston calipers but were designed to haul a 4000lb sedan down from 185mph Autobahn speeds and served duty well on the Nuerburgring Taxis. I think they will be a nice upgrade for my car.

Did you face the rotor hub at all to move the centerline of the rotor disk? That Cobra disk looks like it has less offset than the old parts.
