Description

This kit leverages larger calipers, rotors, and brake pads compared to Ksport's Procomp series, incorporating increased piston count and standard full-floating rotors to enhance caliper self-centering and overall performance. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers offer exceptional strength, lightweight design, and resistance to corrosion. The aluminum pistons further contribute to heat resistance and maintain optimal operation under demanding conditions. The kit features two-piece floating rotors, standard on the Supercomp system, which allow for slight axial shifting for better self-centering within the caliper. This design minimizes brake drag and promotes more even pad application, boosting overall braking efficiency. Included in this kit are SC5 Street Pads, formulated with NAOC Ceramic material. These pads offer optimal performance for both street driving and occasional track use, significantly reducing brake dust (by 50% or more compared to race pads) and minimizing noise and rotor wear. They are designed to operate effectively within a temperature range of 194°F to 1022°F. To complement the braking system, D.O.T compliant stainless-steel braided brake lines are standard. These lines prevent expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel compared to traditional rubber lines. Buyers can choose between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers due to better cooling, and slotted rotors favored for track applications. This Supercomp Big Brake Kit is built to order, with production and delivery typically taking 4-6 weeks. While the kit is listed for 1987-1989 Toyota MR2 GT models, Fitment Industries encourages users to utilize their search bar for a comprehensive list of compatible vehicles, noting that they will confirm ETA within 1-3 days of purchase for backordered items. Ksport offers a wide array of caliper color options, including standard painted colors and premium high-polish finishes, with extensive custom color possibilities available.
