Supercomp Big Brake Kit with Two-Piece Rotor

The Ksport BKMD400-653SO Supercomp Big Brake Kit is engineered to deliver superior stopping power and combat brake fade under demanding conditions. This rear brake kit features a full-floating, two-piece rotor design, paired with your choice of 4, 6, or 8 piston caliper configurations. Designed as a direct bolt-on upgrade, it typically requires no permanent vehicle modifications and installs with basic tools, ensuring a straightforward integration into your vehicle's braking system. The floating rotor technology is crucial for thermal management. The two-piece assembly minimizes rotating and unsprung weight, while the floating outer ring allows for self-centering and prevents thermal stress warping and surface cupping caused by extreme heat. The proprietary slot design enhances the expulsion of gas and pad debris, contributing to reduced brake noise and heat dissipation. Each caliper is CNC-machined from a single billet of aerospace-grade aluminum, ensuring uniform wall thickness and eliminating potential weak spots. The one-piece construction contributes to caliper rigidity, enhanced by a differential bore configuration that optimizes pad contact and pressure distribution. Aluminum pistons with high-temperature seals and stainless-steel brake pad wear plates further contribute to the caliper's durability and performance. The kit includes D.O.T.-compliant stainless-steel braided brake lines, which prevent hose expansion under pressure for a firmer pedal feel and quicker response. It comes standard with NAOC Ceramic street pads, offering an optimal operating range and significantly reducing brake dust and rotor wear compared to race compounds. This specific kit features a slotted rotor design (SO), recommended for performance and track-oriented use due to its superior heat and gas dispersal without excessive pad wear. The kit includes calipers, floating brake discs, brake pads, stainless-steel braided brake lines, and all necessary hardware for installation. All Ksport Big Brake Kits are backed by a 12-month warranty against manufacturer defects.
