Description

The Ksport Dualcomp Big Brake Kit offers a unique dual caliper solution, ideal for performance driving disciplines like drifting and rally racing. Its innovative design integrates a single 4-piston caliper, ingeniously splitting its function with two pistons for the primary foot brake and two for the independent handbrake system. This comprehensive kit is a direct bolt-on, ensuring a straightforward installation process. It comes fully equipped with Ksport's Dualcomp calipers, lightweight two-piece floating brake discs, high-performance NAOC Ceramic SC5 Street Pads, and all the required hardware. For enhanced braking performance and a firmer pedal feel, the kit includes D.O.T. compliant stainless-steel braided brake lines, which resist expansion under pressure. Customization is a key feature, with options for both slotted and cross-drilled rotors. Cross-drilled rotors are recommended for daily drivers as they run cooler, while slotted rotors are better suited for track use. The calipers are available in a range of standard painted colors (Orange, Red, Black, Yellow) and offer premium polished finishes (Silver, Gold, Titanium) or custom color options for a personalized look. This brake kit is also Formula Drift legal. Fitment is confirmed for specific Mitsubishi Lancer Evolution models from 2003-2007. Please note that Ksport Big Brake kits may fit 2WD vehicles only unless otherwise stated, and fitment should always be verified using the vehicle search tool. The product is built to order, with an estimated production and delivery time of 4-6 weeks.
