Overview

This bolt-on system features larger calipers, rotors, and brake pads than the Procomp kit, along with increased pistons and standard full-floating rotors for better self-centering. The calipers are constructed from a solid billet of aircraft-grade aluminum for strength and corrosion resistance, and feature aluminum pistons for enhanced heat resistance.
Show original supplier description
This kit surpasses the Procomp offering with larger calipers, rotors, brake pads, and an increased piston count. Its full-floating rotor design ensures optimal self-centering within the caliper, reducing drag and improving braking consistency. The calipers are meticulously crafted from a single billet of aircraft-grade aluminum, offering exceptional strength-to-weight ratio and long-term corrosion resistance. The kit includes carbon steel caliper brackets, CNC machined to ensure a perfect fit onto your vehicle's OEM caliper bracket locations, accommodating the larger Ksport calipers. Standard on the Supercomp system are floating two-piece rotors. The outer section of these rotors can shift slightly, allowing for better self-centering within the caliper. This feature minimizes brake drag and enhances performance through more uniform pad application. The kit comes with SC5 Street Pads, which provide excellent braking performance for street use and occasional track days, while reducing dust by over 50% and minimizing noise and rotor wear. D.O.T. compliant stainless-steel braided brake lines are also included, preventing line expansion under pressure for quicker pedal response and a firmer pedal feel. Ksport offers customization options for caliper colors, including standard shades like Orange, Red, Black, and Yellow, with premium finishes and custom color options available. You can choose between slotted or cross-drilled rotors; slotted rotors are recommended for track use due to better heat dissipation, while cross-drilled rotors are suggested for daily drivers. Please note that Ksport Big Brake kits are built to order, and production typically takes 4-6 weeks. This kit is specifically designed for the 2008-2016 Scion xB models.
