This is a pretty cost effective solution Cass put together for me. He supplied the re-drilled GM rotors and bolt on brackets. I supplied the GM Metric calipers and line kit. It requires a few little mods on the calipers but overall this is strictly a bolt on upgrade for around $300. You can get the calipers in a 2 3/8 piston, instead of the normal 2 1/2, which with the small 10.5 rotors makes the bias work out good.
