One for usual braking, and one for the e-brake
pretty standard on exotics
and Guero, the 6 pistons on ceramic brakes make a huge difference...though ceramic brakes will sound like there are no pads (screaching) until they warm up.
6 piston is overkill on our cars unless you have a suspension setup to necessitate braking at speeds of over 150 MPH
I just want 4 pistons on cobra rotors without being fisted for the cobra R calipers
It'd be nice to find another 4 piston that is more common that would bolt up....like a vette or mercedes caliper
