Description

The Ksport Dualcomp Big Brake Kit offers a significant upgrade in stopping power for the rear of your vehicle. This kit features a 4-piston caliper system paired with 330mm drilled rotors, designed to improve performance over stock brake components. The included SC5 Street Brake Pads provide reliable street performance, while the stainless steel brake lines help to eliminate line expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel. This kit is engineered as a complete bolt-on solution, requiring minimal tools and no permanent modifications to your vehicle for installation. The Dualcomp system, with its dual caliper design, is particularly suited for applications like drifting and rally racing, offering enhanced braking control. The rotors are available in either cross-drilled or slotted options; cross-drilled are recommended for daily driven vehicles due to cooler operating temperatures, while slotted rotors are advised for track use. Ksport Big Brake kits are built to order, so please allow for a production and delivery lead time of 4-6 weeks. It is crucial to verify fitment for your specific vehicle before ordering. If any issues arise due to our sales team's recommendation of an incompatible setup, we will work to resolve the situation and may waive restocking fees if the item is returned in like-new condition. Always inspect items upon delivery and notify us immediately of any concerns or missing parts to avoid installation delays.
