Description

The Ksport Procomp Big Brake Kit offers a significant upgrade in stopping power for your vehicle. The kit is intended for straightforward installation, requiring minimal tools for most applications. At the core of this kit are the Ksport ProComp 8 Piston calipers, finished in a striking red. Machined from aircraft-quality billet, these calipers are extremely lightweight (just over 5 lbs each) and feature a differential bore configuration for optimal performance. They boast an opposed piston design, which enhances both pad wear and caliper rigidity compared to OEM components. Standard features include aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. The kit also includes stainless steel brake lines to prevent expansion under pressure, ensuring consistent braking performance. The braking system incorporates a 2-piece floating disc assembly, which contributes to reduced rotating and unsprung weight. This floating design also mitigates thermal stresses, preventing the rotor from warping or cupping. The rotors feature a unique slot design that not only reduces braking noise but also efficiently expels gas and pad debris. These rotors are heat-treated and balanced for peak performance. While cross-drilled rotors are recommended for daily driven vehicles due to cooler operation, the slotted rotors in this kit are ideal for vehicles that see more track use. This specific kit is designed for the 1989-1994 Nissan Skyline R32 chassis with a 4x114.3 bolt pattern.
