Just a comment about front brake performance. I have the Byers, Willwood 4 piston calipers and hats all around, and the larger rotors up front. Had to add a proportioner (pressure reducer) on the front circuit because the front brakes were too powerful. Locked up easily.
The car stops like a mad dog now, but know that if you improve the brakes with modern components, the fronts will need to be dialed back.
