[QUOTE="ShelbyGuy, post: 3957091, member: 10042"] pressures are not going to vary unless you change the master cylinder, and the master cylinder has enough piston swept area to feed just about any caliper you're going to find. the pressure applied to the caliper pistons depends on the diameter of the master cylinder piston and the leverage applied by the brake pedal (eg., how far down from the pivot point the master cylinder pushrod is) going to a caliper with bigger and more pistons does not increase brake pressure. quite the opposite. i was more concerned with deceleration g-forces being greater than what the algorithm in the abs ecu would expect. my math says that a 14" rotor isnt going to apply much more brake torque than a 13" rotor, but a 14" rotor and slicks combined with threshold braking might tickle something.
