Brake Clinic

Yeah not on a street car...I think they probably mean more rear brake bias than most street cars.  Porsche lawyers are why we don't have enough factory front camber, they try to make the car push, so rear bias makes no sense.

The real indication of PSM acting in this fashion is that you will likey see the left and right rear pads wearing differently.  That side to side wear is a clear indication of PSM because you can't do that with the pedal.


IMHO, it's not so much the traction control/pseudo LSD aspect of the PSM but the stability feature that causes this wear.  PSM also uses the throttle, so it won't let you put so much power to the wheels that it has to use the brakes, it can just reduce the throttle.  Don't believe me? Try dragging the brake whilest accellerating, PSM with cut the throttle.
