Overview

This kit features an extreme lightweight SuperComp caliper machined from aircraft quality billet, with a differential bore configuration and larger pistons than ProComp calipers. It includes aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, with an opposed piston caliper design for improved pad wear and rigidity. The kit utilizes stainless steel brake lines to prevent expansion under pressure and comes with 4 brake pads per caliper due to the larger size. SuperComp systems include a 2-piece floating disc assembly to reduce weight and prevent warping from thermal stress.
Show original supplier description
This kit features an extreme lightweight SuperComp caliper, weighing just over 7lbs each, constructed from aircraft quality billet. The caliper boasts a differential bore configuration with significantly larger pistons than ProComp calipers, incorporating aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. Its opposed piston design enhances pad wear and caliper rigidity compared to OEM systems, while the included stainless steel brake lines prevent expansion under pressure. Due to the substantial size of the SuperComp caliper, four brake pads are standard per caliper. The SuperComp systems are equipped with a 2-piece floating disc assembly. This design reduces both rotating and unsprung weight, and the floating nature of the disc dissipates thermal stresses from extreme heat, preventing warping or cupping of the braking surface. The rotors feature a unique slot design that minimizes braking noise and accelerates the expulsion of gas and pad debris. Each rotor is heat-treated and balanced for optimal performance. While cross-drilled rotors offer cooler operation and are recommended for daily drivers, the slotted rotors in this kit are advised for vehicles experiencing more track use than daily driving.
