Performance Friction ZR31 Monobloc Big Brake Kit Rear Porsche 911 996

PFC's forged aluminum monobloc calipers are incredibly lightweight and have superior stiffness for quicker actuation, increased pedal response, less pedal travel, and decreased drag. The race-inspired radial mount improves torque takeout, allowing your car to optimize every ounce of horsepower and deliver more power at the wheel end. PFC’s patented piston heat caps allow the caliper the caliper to achieve the coolest running temperatures—up to 50-100°F— which further increases stiffness and decreases drag.

  • Monoblock Caliper

    PFC's Monobloc caliper is one of the very best. Using only hi-temp billet and aerospace fasteners, Performance Friction's calipers feature stiffness-to-mass second to none! To ensure the best operation both on the track and off, PFC calipers use heat caps on the piston to reduce heat soak into the caliper. Thanks to a multi-pad design, these are some of the most responsive calipers on the market. Multi-pad calipers have individual pads for each piston to ensure the best release characteristics and pad utilization.

    Performance Friction calipers are not massive 6 or 8 piston calipers. Instead all PFC calipers are torque optimized for each vehicle. Ensuring you get the most of your setup and vehicle. More pistons do not always equal more stopping power.
