How the caliper distrubtes clamping force on the back of the caliper, single v.s. dual v.s. four piston calipers. A dual piston PBR caliper has a MUCH larger brake pad surface area and the caliper distributes the clamping force MUCH more evenly over the rear of the pad than a stock caliper. Same thing is true for the 11" S10 balzer upgrade. That brake upgrade is going to be significantly better than the stock brakes because it has a significantly larger brake surface with calipers that distribute pressure more evenly. It's not how hard the caliper clamps but how much surface area and how it is distributed that make the difference.

There are other factors that play into this also including how the caliper is mounted. The PBR is a full floating design and not a fixed mount design like the Dynalite in the Wilwood kit. I don't know enough about this stuff but I do know that is important in a road race/ street car brake setup.

Just my point of view, thanks for compiling the info though and it is good for comparing the differences.
