Description

This sophisticated bolt-on system builds upon the Procomp kit with larger calipers, rotors, and brake pads, augmented by an increased piston count and standard full-floating rotors for superior self-centering within the caliper. Each caliper is meticulously crafted from a single billet of aircraft-grade aluminum, ensuring a lightweight yet exceptionally strong and corrosion-resistant component. Aluminum pistons are incorporated for enhanced heat resistance and reliable operation under demanding conditions. The two-piece floating rotor design allows the outer section to shift slightly, improving self-centering, reducing brake drag, and ensuring more even pad application for enhanced performance. The kit comes standard with SC5 Street Pads, formulated with NAOC Ceramic material for optimal street and occasional track use, offering reduced dust (by 50% or more), noise, and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. D.O.T. compliant stainless-steel braided brake lines are also included, preventing line expansion under pressure for a quicker pedal response and a firmer pedal feel. Customers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily drivers due to better cooling, while slotted rotors are suggested for track-focused vehicles. The Supercomp kit is built to order, with production and delivery typically taking 4-6 weeks. This rear big brake kit is compatible with 2011-2018 Infiniti Q70 and M37 models, specifically noted for RWD configurations.
