Description

This kit integrates a lightweight, one-piece caliper CNC-machined from aircraft-quality billet aluminum. The caliper features a differential bore configuration, aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. Its opposed-piston design significantly improves pad wear and caliper rigidity compared to OEM components. The kit utilizes a two-piece disc assembly that reduces both rotating and unsprung weight. Many applications offer a floating disc option to mitigate thermal stresses and prevent warping. The rotors feature a unique slot design that minimizes braking noise and efficiently expels gas and pad debris. For optimal performance, all rotors are heat-treated and balanced before shipment. Cross-drilled rotors are recommended for daily drivers due to their tendency to run cooler, while slotted rotors are suggested for track-focused vehicles. The Ksport Supercomp Big Brake Kit includes replacement calipers, rotors, pads, stainless steel brake lines, and all necessary hardware. The SuperComp rotors also feature a full-floating design for improved self-centering, which reduces brake drag and enhances overall performance. The kit is available with Super 8 Pot Calipers in various sizes for front and rear applications, and comes in standard colors like Orange, Red, Yellow, and Black, with over 20,000 custom color options available. Ksport offers a 12-month warranty against manufacturer defects for all big brake kits. Fitment: This kit is specifically designed for the Subaru Legacy BL9 models from 2003-2009, including the 2.5 GT and Wagon GT variants.
