Description

This complete bolt-on system integrates a unique setup where a single 4-piston caliper divides its braking force: two pistons engage for the primary foot brake, while the other two operate the independent handbrake system, providing enhanced control. The kit comes standard with SC5 street performance pads, designed to deliver optimal braking in street and occasional track conditions while minimizing dust and noise. For further customization, options for slotted or cross-drilled rotors are available, with slotted recommended for track use and cross-drilled for daily driving. Installation is facilitated by CNC-machined carbon steel caliper brackets that allow the larger Ksport calipers to bolt directly onto the OEM caliper bracket locations. Additionally, a polished titanium handbrake cylinder and lever enhance both the aesthetics and control of the handbrake. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. The kit is Formula Drift legal and includes everything needed for installation: calipers, floating brake discs, brake pads, handbrake, and all necessary hardware. Caliper color options are extensive, ranging from standard painted finishes like orange, red, black, and yellow to premium high-polish finishes and custom color options.
