Description

The Ksport DualComp Big Brake Kit offers an ultimate all-in-one Dual Caliper solution, specifically engineered with drifting and rally racing in mind. This rear brake kit utilizes a sophisticated 4-piston caliper setup where the brake system is split, with two pistons dedicated to the primary foot brake and two pistons for the handbrake, each running on its own independent system. This design ensures optimal performance and control for demanding driving conditions. This is a complete, direct bolt-on system, meaning it comes with everything required for installation. The package includes Ksport's CNC-machined Carbon Steel caliper brackets, which facilitate easy mounting to the OEM caliper bracket location. The kit features lightweight, two-piece rotors that can be specified as either slotted or cross-drilled for customizable performance and cooling characteristics. Cross-drilled rotors are recommended for daily driving due to better cooling, while slotted rotors are better suited for track use. The calipers themselves are available in standard painted colors like Orange, Red, Black, and Yellow, with premium high-polish finishes and over 20,000 custom color options available. Included are SC5 Street Pads, which provide optimal braking performance for street use and occasional track days, while minimizing brake dust and noise. The kit also features D.O.T. compliant stainless-steel braided brake lines that prevent line expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to stock rubber lines. A polished Titanium handbrake cylinder and lever are also part of the system, enhancing both aesthetics and control. Ksport Big Brake kits are built to order, and customers should allow 4-6 weeks for production and delivery. Ksport advises confirming fitment before ordering, as incorrect orders may be subject to restocking or cancellation fees. If a fitment issue arises from a sales team recommendation, the company aims to resolve it. For returns, items must be new, unopened, and within 30 days of delivery, with shipping costs covered if the error was on Ksport's part.
