Just for reference, I weighed my factory SRT front rotor and caliper.......
Caliper = 15 pounds 13oz
Rotor = 25 pounds 3oz
That is 29 pounds on each side.....

and the C32 rotors are 15mm bigger.... But the C32 calipers are lighter than factory SRT ones.....

I need some of those nice 2 piece RacingBrake rotors.......
