Description

Designed as a sophisticated bolt-on system, it requires no vehicle modifications for installation. This kit significantly enhances braking performance by incorporating larger calipers, rotors, and brake pads, along with an increased number of pistons. The Supercomp calipers are machined from a solid billet of aircraft-grade aluminum, offering exceptional strength, light weight, and corrosion resistance. They feature aluminum pistons for superior heat tolerance and reliability. Further enhancing performance, the Supercomp kits include standard full-floating two-piece rotors. This design allows the rotor's outer section to shift, providing better self-centering within the caliper. This not only reduces brake drag but also ensures more even pad application, leading to improved braking efficiency. Ksport offers a choice between slotted and cross-drilled rotors; cross-drilled are recommended for daily driven vehicles due to their cooler operating temperatures, while slotted rotors are better suited for track use where heat management and debris expulsion are critical. The kit comes equipped with SC5 Street Pads, which provide optimal braking performance for street driving and occasional track sessions. These pads are formulated to reduce brake dust by over 50% compared to race pads, while also minimizing noise and rotor wear. They maintain optimal performance within a temperature range of 194°F to 1022°F. Additionally, all Ksport Big Brake Kits include D.O.T. compliant stainless steel braided brake lines, which eliminate line expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. Custom caliper color options are available, including standard painted finishes (Orange, Red, Black, Yellow) and premium high-polish options (Silver, Gold, Titanium), with over 20,000 custom color finishes also being an option. This kit is specifically designed to fit various Infiniti M37, M56, and Q70 models from 2011-2018, including specific trims like Base, Luxe, and Q70L. Customers should verify fitment with their specific vehicle details.
