Show original supplier description
The Ksport Supercomp Big Brake Kit represents the pinnacle of brake system upgrades, engineered to deliver unparalleled stopping power for your 2010-2013 Subaru Legacy. This kit is designed as a direct bolt-on, eliminating the need for any vehicle modifications, and integrates seamlessly with your existing setup. It builds upon the foundation of the Procomp kit by incorporating larger calipers, rotors, and brake pads, an increased number of pistons for superior force distribution, and standard full-floating rotors that enhance self-centering capabilities for reduced drag and more consistent braking. Constructed with meticulous attention to detail, the calipers are forged from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-resistant foundation. These calipers utilize aluminum pistons, which offer superior heat resistance compared to other materials, maintaining optimal performance even under extreme conditions. For rotor options, you can choose between slotted rotors, recommended for track use due to their superior heat dissipation, or cross-drilled rotors, ideal for daily driven vehicles as they run cooler. The kit comes standard with "SC5 Street Pads," a high-performance ceramic compound that offers excellent braking in street and occasional track conditions, significantly reducing dust and noise while minimizing rotor wear. Additionally, all Ksport Big Brake Kits feature D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel than stock rubber lines. Ksport Big Brake kits are built to order and require an estimated production and delivery time of 4-6 weeks. If you encounter any fitment issues, Ksport and its retailers are committed to assisting, with policies in place to address any errors or recommendations made by their sales team, ensuring a fair resolution including no restocking fees if fitment is confirmed by them and the product does not fit, provided the item remains in like-new condition.
