The LS1 rotor is 5*4.75. A good dual piston caliper will be made out of aluminum so it will be lighter. Reducing unsprung mass. The dual pistons have a higher surface area than the single piston requiring less force for equal braking. And a good caliper, like the LS1/Corvette PBR design...

The caliper is totally different from what I am told. The rotors supposedly used all the same bearing hardware and that is why a 1LE rotor fits on a B-Spindle. I guess the B-Spindle ears don't match up with the 1LE caliper...

Have a few related questions: First of all, does anyone know of a simple dual piston caliper upgrade for the B-Spindle? Second, this conversion makes use of the F-body 1LE rotor(12" * 1") on the B-Spindle. On an Impala SS board, I read the 9C1 Caliper was designed to fit around a 1.25"...
