You can fix braking problems in stages as budget and courage allows. For those with the big 4 pot AP front calipers and big rotors, the fix is a biasing cage and radial mounted rear calipers. /* ]]> */ Analysis of the vehicle deceleration data combined with the measured torque values and knowledge of the vehicle parameters mentioned above (wheelbase, CG height, weight on each axle at rest) allow us to calculate brake bias for that particular event. The front bias is simply out of hand with that combination: bigger front rotors and calipers. I have a few follow ups -. In my search to abate the ice-mode issue I tried installing Hawk HP+ pads.
