We had a set of calipers from the Mitsubishi Evolution laying around, and we thought we'd see how they compare to our big brake upgrade for the same application. Although we didn't have a factory Evo rotor laying around, we knew that it weighed in at 21.35 for the front rotor. Above we're weighing the front caliper at 7.85. Without the factory pads, this already weighs in at 29.2 lbs.

As you see, the Performance Friction Big Brake kit, complete with our brake pads weighs in at 25.15 lbs, a 4 pound weight saving over the factory brakes. So not only do you save weight on all four corners, but stopping power is greatly increased.
