1-Piece Billet Aluminum Caliper with Aluminum Pistons

This kit features 8-piston calipers, crafted from a solid billet of aircraft-grade aluminum for a combination of lightweight construction, unparalleled strength, and corrosion resistance. The aluminum pistons within the calipers offer superior heat resistance and ensure uncompromised operation. The two-piece rotors provide fade-free performance and effective grip for track use, while also offering comfortable operation for daily driving. Standard SC5 Street Pads are included, offering optimal braking performance for street and occasional track use, with reduced dust and noise compared to race pads. D.O.T. compliant stainless-steel braided brake lines are also standard, improving pedal response and feel. Ksport offers customization options for the calipers, which come standard in colors like Orange, Red, Black, and Yellow. Premium high-polish finishes and custom color options are also available. For the two-piece rotors, customers can choose between cross-drilled or slotted designs. Cross-drilled rotors are recommended for daily-driven vehicles as they run cooler, while slotted rotors are suggested for more frequent track use. This big brake kit is specifically designed to fit Subaru Impreza WRX STI models from 2015-2021, including trims like the 6 Man and Base. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
