Description

The Ksport BKMZ300-446CO Supercomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver maximum stopping power with no vehicle modifications required in most applications. This kit represents a significant step up over OEM braking systems for both street performance and track use. The calipers are machined from a solid billet of aircraft-grade aluminum, featuring a differential bore, opposed-piston configuration for even pad wear and rigidity. They utilize aluminum pistons for superior heat resistance and high-temperature seals with stainless-steel pad wear plates. This floating design absorbs thermal stress to prevent warping, and the unique slot design expels gas and debris efficiently while minimizing noise. The cross-drilled rotor style is recommended for daily driven vehicles as it runs cooler. Included are DOT-compliant stainless-steel braided brake lines that resist expansion for a firmer pedal feel. The kit comes with NAOC Ceramic brake pads, which have an optimal operating range of 194°F–1022°F, reduce brake dust by over 50%, and minimize rotor wear and noise. The kit includes billet aluminum caliper(s), floating cross-drilled brake disc(s), ceramic brake pads, stainless-steel braided brake lines, CNC machined carbon steel caliper bracket(s), and all required hardware. Ksport calipers are available in various painted finishes including Orange, Red, Black, and Yellow, with premium high-polish and anodized options also available. All Ksport Big Brake Kits are backed by a 12-month manufacturer defect warranty.
