If you feel you have premature front lockup (ABS trigger point) Have you checked corner balance ? The 911,s pre ABS were front biased and a sure sign of a corner balance issue was premature front lockup one side first. Today an ABS equipped car would disquise the problem by triggering the ABS early because one front wheel was light

Remember that due to driving dynamics, at least 70% of your braking power is always on the front tires because that is where weight transfer moves under braking. The last thing you want is to have the rear wheels go into ABS before your front tires have reached max braking power. That would greatly lengthen stopping distances. We want the front to go into ABS first for maximum braking but getting the rear closely balanced is a valid goal.

Try Pagid Yellow F/ Black R to create more clamping force on the rear as many Spec cars do. Reducing stagger by running 245/265 or 255/275 will add grip forward and also move braking bias forward. More grip up front also means more heat in the front brakes. No problem if you run the right pads and fluid.
