Description

This innovative kit features a unique dual caliper design, utilizing a single 4-pot caliper where two pistons handle the primary foot brake and the other two are dedicated to the handbrake, each operating on its own independent system. This setup provides enhanced control and stopping power. The kit is a complete, bolt-on solution, simplifying installation with all necessary components included: calipers, two-piece floating brake discs, SC5 Street Pads, and all required hardware. For improved pedal feel and response, the kit incorporates D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure. Ksport offers customization for the rotors, with options for either cross-drilled or slotted designs. Cross-drilled rotors are recommended for daily driving as they run cooler, while slotted rotors are better suited for track use. The calipers are available in standard painted colors like orange, red, black, and yellow, with premium high-polish finishes and custom color options also available. It is important to note that Ksport Big Brake kits typically fit 2WD vehicles unless otherwise stated. The Dualcomp Big Brake Kit is Formula Drift legal. Ksport Big Brake kits are built to order, and customers should allow 4-6 weeks for production and delivery.
