Overview

The Ksport SuperComp Big Brake Kit provides ultimate stopping power for your vehicle. The extreme lightweight SuperComp caliper is machined from aircraft quality billet, featuring differential bore configuration with larger pistons than ProComp calipers.
Show original supplier description
By integrating advanced brake technology, this kit significantly reduces brake fade and continuously cools and refreshes the brake pad surface under demanding use. The SuperComp caliper itself is a marvel of engineering, machined from aircraft-quality billet aluminum and weighing just over 7 lbs. It features a differential bore configuration with pistons significantly larger than those found in Ksport's ProComp calipers. Standard features include aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity compared to OEM setups, while stainless steel brake lines prevent expansion under pressure. This specific kit utilizes 4 brake pads per caliper due to the caliper's larger size. Complementing the calipers are the 2-piece floating disc assemblies. These not only reduce rotating and unsprung weight but also mitigate thermal stresses from extreme heat, preventing disc warping or cupping of the braking surface. The unique rotor slot design is optimized to reduce braking noise and more efficiently expel gas and pad debris. Every rotor is meticulously heat-treated and balanced before shipment to ensure peak performance. The description notes that slotted rotors are recommended for vehicles experiencing more track use than daily driving, while cross-drilled rotors tend to run cooler and are suggested for daily-driven vehicles.
