6-Piston Caliper Big Brake Kit

The Ksport Procomp Big Brake Kit provides enhanced stopping power, specifically for the rear of your vehicle. The kit integrates advanced brake technology that continually cools and refreshes the brake pad surface during braking, ensuring consistent performance. Key components include Ksport's extreme lightweight 6-piston caliper, precision-machined from aircraft-quality billet. The caliper features a differential bore configuration, weighs just over 5lbs, and incorporates protection grooves for bridge tubes. Standard features on each caliper 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 systems, while the included stainless steel brake lines resist expansion under pressure. This kit utilizes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. The floating design also mitigates thermal stresses from extreme heat, preventing disc warping or cupping of the braking surface. The 380mm (15-inch) slotted rotors are heat-treated and balanced for optimal performance, with the unique slot design expelling gas and pad debris effectively. Slotted rotors are recommended for vehicles that see more track use. Application: This specific kit (BKNS151-653SO) is designed for the 1989-1994 NISSAN SKYLINE GTS R32 Chassis.
