Description

This sophisticated, bolt-on kit enhances the performance of Ksport's Procomp system by incorporating larger calipers, rotors, and brake pads, alongside an increased number of pistons. The Supercomp kit utilizes standard full-floating rotors, which improve caliper self-centering and reduce drag for more consistent braking. All calipers are constructed from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-resistant component. The calipers also feature aluminum pistons for superior heat resistance and reliable operation. Key features of this kit include a forged one-piece caliper constructed from aerospace-quality aluminum for exceptional strength and even thickness distribution. Carbon steel caliper brackets, CNC machined for precision, facilitate direct bolt-on installation to your OEM caliper bracket locations, accommodating the larger Ksport calipers. The floating two-piece rotor design allows the outer section to adjust, promoting better self-centering within the caliper, minimizing brake drag, and ensuring more even pad application for enhanced performance. The kit comes standard with NAOC Ceramic SC5 street pads, which offer optimal braking for street and occasional track use, reducing brake dust by over 50% and minimizing noise and rotor wear with optimal operating temperatures between 194°F and 1022°F. D.O.T. compliant stainless-steel braided brake lines are also included, preventing hose expansion under pressure for a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Customers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily driven vehicles due to better cooling, while slotted rotors are suggested for track-focused applications. This Ksport Big Brake Kit is designed to fit 2WD vehicles only, unless otherwise specified. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. Fitment is confirmed for the Subaru Legacy from 2004-2009, with specific compatibility for models like the 2009 Subaru Legacy 2.0R. It is crucial to confirm fitment before ordering, and Fitment Industries offers assistance to ensure you select the correct product. If a fitment issue arises due to a recommendation from their sales team, they will work to make the return process easier, potentially waiving restocking or return shipping costs if the item is in like-new condition.
