Nice work Howard.
Going back to the brakes, maybe a little late for this thread, you can get the rotors from Coleman racing and they will do any work you feel required to them, like balancing, stress relief, cutting slots, etc. They also can set them up for t-slot fasteners so they float, a bolt on replacement for solid mounting. I found that even though mine were aligned very well and there was no knock back, there was a noticeable difference changing to the floating rotors on coast down.
