Description

The Ksport Supercomp Big Brake Kit is an extreme upgrade engineered to deliver the highest level of stopping power for your Nissan 300zx Z32 (1990-1996). This sophisticated bolt-on system requires no vehicle modifications for installation and features larger calipers, rotors, and brake pads compared to standard offerings. It also includes standard full-floating rotors for improved self-centering within the caliper, reducing drag and enhancing performance. Constructed from a solid billet of aircraft-grade aluminum, the one-piece caliper design ensures lightweight, unparalleled strength, and resistance to corrosion. The calipers incorporate aluminum pistons for superior heat resistance. Carbon steel caliper brackets, CNC machined for precision, facilitate direct bolt-on installation to OEM locations. The kit features a two-piece floating rotor design where the outer section can shift slightly, improving self-centering and minimizing brake drag. Standard SC5 Street Pads are included, offering optimal performance for street and occasional track use, with reduced dust and noise. Further enhancing performance and feel, the kit includes D.O.T. compliant stainless-steel braided brake lines that prevent expansion under pressure, resulting in quicker pedal response and a firmer pedal feel. Buyers can choose between slotted or cross-drilled rotors; slotted is recommended for track use, while cross-drilled is suggested for daily drivers due to better cooling. The standard kit includes two forged monoblock aluminum calipers, two lightweight two-piece rotors, a set of SC5 Street Brake Pads, stainless steel brake lines, all necessary mounting components and hardware, and an owner's manual. Note that Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This system is appropriate for 19-inch wheels and above.
