how much did the e-diff help? Whenever I hear of a new car technology doing the braking for me (i.e. DSC) then I picture a car going around the autox course slower than without it.
I am also afraid of wearing out the rear brakes with the e-diff thing going off all the time at the autox. My buddy wore out his rear brakes before his fronts just by having his DSC on when driving winding roads on the weekend.
