Description

This rear big brake kit is designed as a sophisticated bolt-on system, ensuring the highest level of stopping power without the need for vehicle modifications. It builds upon the foundation of the Procomp kit by incorporating larger calipers, rotors, and brake pads, along with an increased number of pistons and standard full-floating rotors that promote better self-centering within the caliper for improved performance and reduced brake drag. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers offer exceptional lightweight strength and are resistant to corrosion. The calipers feature aluminum pistons, which provide superior heat resistance and maintain uncompromised operation under extreme conditions. The floating two-piece rotor design allows the outer section to shift slightly, further aiding self-centering and ensuring consistent, even brake application for optimal performance. This kit includes SC5 Street Pads, which offer optimal braking performance for both street driving and occasional track use, while reducing brake dust by over 50% and minimizing noise and rotor wear. DOT-compliant stainless-steel braided brake lines are also standard, eliminating line expansion under pressure for a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Customers can choose between slotted or cross-drilled rotors; cross-drilled are recommended for daily drivers due to better cooling, while slotted rotors are suggested for track-focused vehicles. The Supercomp Big Brake Kit is built to order, with an estimated production and delivery time of 4-6 weeks. Fitment is available for select Infiniti Q45 models, specifically the 1997-2001 model years, with confirmed applications including the 2002 and 2006 Base trims. The manufacturer emphasizes that while they strive for accurate fitment guidance, buyers should always confirm compatibility for their specific vehicle before ordering. In cases where the sales team recommends an incompatible setup, Ksport or its retailers will work to rectify the situation, potentially accepting returns with no restocking fees if the item remains in like-new condition.
