Front to rear brake bias is important not only from a control and dynamics perspective, but it impacts stopping distance as well. Most track cars still retain a slight frontward bias for control reasons under braking.
Brake bias is largely determined by your bbk piston sizing or other hydrolic components.
Many argue you don't need full track pads in the rear, due to the lower heat strain. I've had this discussion on the forums before, and many argue it has a very minute impact. This is just wrong. I've long held that you need high friction rear pads in order to balance out or at least maintain the brake bias on our cars.
Proof: I just swapped the right front for some typical performance street pads. the left front retained CarboXP12's. immediately I could feel the pulll to the left. I bedded the pads in, let the car cool, and gave it another go thinking this might explain it. Went back out, and the pulling sensation to the left was just as bad. So bad, that I could fully lock up the front left before the front right even began to chirp.
So next time you go out to the track, think twice about those hyrbrid pads in the rear being adequate -- heat isn't the only concern here.
