|The 13 front system uses a 13 cross-drilled, gas
slotted and zinc washed rotor, mounted to a 2024 T6 billet aluminum CNC
machined anodized hub and a PBR C15 caliper that attaches to the spindle
with CPP custom caliper mounting brackets. PBR C15 calipers have twin 52mm
pistons and a larger brake pad surface area that offers about 60% more stopping
power in the caliper than the popular C5 caliper at half the cost. Big Brake
kits require larger diameter disc brake type wheels: our 13 kit requires
17 wheels. (easy-to-use wheel template available).
