Description

The Ksport Supercomp 8-Piston 421mm Front Big Brake Kit represents the pinnacle of braking upgrades, engineered to deliver unparalleled stopping power for your Honda CR-Z (2010-2016). This sophisticated, bolt-on system requires no vehicle modifications for installation, offering a seamless integration. It builds upon the Procomp kit's foundation with significantly larger calipers, rotors, and brake pads, augmented by an increased number of pistons and standard full-floating rotors that enhance self-centering within the caliper for reduced drag and more consistent application. Constructed from aerospace-quality aluminum, the lightweight forged one-piece calipers ensure exceptional strength, corrosion resistance, and uniform thickness. The kit includes Ksport's SC5 Street Pads, providing optimal braking under street conditions and occasional track use, with benefits like reduced dust (by 50% or more), quieter operation, and less rotor wear, all within an optimal operating temperature range of 194°F - 1022°F. Supporting these components are CNC-machined Carbon Steel caliper brackets that facilitate direct bolt-on installation to the OEM caliper bracket location. The braking system is further enhanced by D.O.T. compliant stainless-steel braided brake lines, which prevent hose expansion under pressure for a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Customization is key with Ksport's Supercomp kits. You can choose between Slotted or Cross Drilled rotors. Cross Drilled rotors are recommended for daily-driven vehicles as they run cooler, while Slotted rotors are better suited for track-focused applications. Calipers are available in standard painted colors (Orange, Red, Black, Yellow) with options for premium high polish finishes (Silver, Gold, Titanium) and Glassy/Hard Anodized Colors, offering over 20,000 custom color possibilities. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. Fitment is confirmed for specific Honda CR-Z models from 2010-2016, with additional compatible vehicles available through Fitment Industries' extensive vehicle search tool. If fitment is confirmed by Fitment Industries' sales team and the product does not fit, returns will be accepted with no restocking fees, provided the item remains in like-new condition.
