Overview

The Ksport Supercomp Big Brake Kit is an extreme brake upgrade designed for maximum stopping power on your Infiniti Q45. This sophisticated bolt-on system requires no vehicle modifications for installation and features larger calipers, rotors, and brake pads than their Procomp kit. The calipers are constructed from a solid billet of aircraft-grade aluminum for strength and corrosion resistance, and utilize aluminum pistons for better heat management. The kit includes D.O.T. compliant stainless-steel braided brake lines for improved pedal response.

The Supercomp kit features a floating two-piece rotor design for better self-centering and reduced brake drag. Rotors are available in cross-drilled or slotted options, with cross-drilled recommended for daily driven vehicles and slotted for track use. This front kit includes a set of SC5 Street Brake Pads, offering optimal performance for street and occasional track conditions while reducing dust and noise.
Show original supplier description
The Ksport Supercomp 8 Piston Front Big Brake Kit is engineered to deliver the highest level of stopping power for your Infiniti Q45 (1997-2001). This extreme brake upgrade is designed as a sophisticated, direct bolt-on solution, eliminating the need for any vehicle modifications. Key features include a lightweight forged one-piece caliper constructed from a solid billet of aerospace-quality aluminum, offering unparalleled strength and resistance to corrosion. These calipers house aluminum pistons for superior heat resistance and consistent operation. The kit utilizes CNC machined carbon steel caliper brackets to ensure a direct fit to the OEM caliper bracket location. The Supercomp system is equipped with floating two-piece rotors, standard on all kits, which allow for slight shifting for better self-centering within the caliper. This reduces brake drag and enhances performance through more even pad application. Rotors are available in either cross-drilled (recommended for daily drivers due to cooler operation) or slotted (recommended for track use) styles. This kit comes standard with SC5 Street Brake Pads, formulated for optimal performance in street and occasional track conditions, while significantly reducing brake dust and rotor wear. D.O.T. compliant stainless-steel braided brake lines are also included, providing a firmer pedal feel and quicker response by preventing expansion under pressure. The standard kit includes (2) forged Monoblock aluminum calipers, (2) lightweight two-piece rotors, (1) set of SC5 street brake pads, (2) stainless steel brake lines, and all necessary mounting components and hardware. Ksport Big Brake kits are built to order, with production and delivery times typically ranging from 4-6 weeks.
