Show original supplier description
The Ksport Dualcomp Big Brake Kit is engineered as a comprehensive Dual Caliper solution, specifically developed for the demands of drifting and rally racing. This innovative system employs a single 4-pot caliper, intelligently configured with two pots dedicated to the foot brake and two pots for the handbrake, each functioning independently within its own system. The kit provides a complete bolt-on experience, arriving with all essential components, including calipers, lightweight two-piece floating brake discs, performance brake pads, a polished titanium handbrake cylinder and lever, and all required hardware for straightforward installation. Ksport allows for significant customization to suit your driving needs. You can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily driven vehicles due to their cooler operating temperatures, while slotted rotors are suggested for those who frequently engage in track driving. The kit includes SC5 Street Pads, which deliver optimal braking performance for both street use and occasional track sessions, while also reducing brake dust by over 50% compared to race pads and minimizing noise and rotor wear. The optimal operating temperature range for these pads is between 194°F - 1022°F. Further enhancing the performance and feel are the D.O.T. compliant stainless-steel braided brake lines, standard in all Ksport Big Brake kits. These lines prevent expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Ksport offers a wide array of custom caliper color options, including standard painted colors like Orange, Red, Black, and Yellow, with premium high-polish finishes and over 20,000 custom color choices available for a truly personalized look. Ksport Big Brake kits are built to order, so please allow 4-6 weeks for production and delivery.
