Description

This kit builds upon the foundation of Ksport's Procomp system, incorporating larger calipers, 400mm rotors, and enhanced brake pads. It also features an increased piston count and standard full-floating rotors that promote better self-centering within the caliper, reducing drag and improving braking consistency. Constructed for uncompromising strength and lightness, the calipers are forged from a single billet of aircraft-grade aluminum, ensuring durability and corrosion resistance. Aluminum pistons are utilized for superior heat management. The two-piece floating rotor design allows for slight shifts, further optimizing self-centering, minimizing brake drag, and ensuring more even pad application for enhanced performance. Ksport offers a wide array of caliper color options, from standard painted finishes to premium high-polish and custom anodized colors, allowing for extensive personalization. This kit comes standard with SC5 Street Pads, which provide optimal braking for street driving and occasional track use, offering a significant reduction in brake dust, noise, and rotor wear. Buyers can choose between slotted or cross-drilled rotors, with slotted recommended for track use and cross-drilled for daily drivers due to their cooler running temperatures. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
