Overview

The Ksport Supercomp 8-Piston Big Brake Kit is an extreme braking upgrade designed for the Suzuki SX4 2008-2013. This sophisticated, bolt-on system provides high stopping power without requiring vehicle modifications. It features larger 330mm rotors, 8-piston calipers, and full-floating rotor design for improved self-centering. The calipers are constructed from a one-piece billet of aircraft-grade aluminum for strength and corrosion resistance, with aluminum pistons for better heat management.
Show original supplier description
This advanced system builds upon the capabilities of Ksport's Procomp kit, incorporating larger calipers, rotors, and brake pads, an increased number of pistons, and standard full-floating rotors that enhance caliper self-centering for reduced drag and optimized performance. Constructed from a solid billet of aircraft-grade aluminum, the one-piece caliper design ensures lightweight construction, exceptional strength, and resistance to corrosion. The calipers are equipped with aluminum pistons, which offer superior heat resistance and maintain reliable operation. The floating two-piece rotor design allows the outer section to adjust as needed, further contributing to even brake application and performance. This kit includes Ksport's SC5 Street Pads, formulated for optimal braking in street and occasional track use, offering a significant reduction in brake dust and noise. The D.O.T. compliant stainless-steel braided brake lines are also standard, providing a firmer pedal feel, quicker pedal response, and preventing line expansion under pressure. Buyers can choose between slotted or cross-drilled rotors, with cross-drilled recommended for daily driving due to cooler operation, and slotted for track-focused vehicles. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
