Big Brake Kit with Slotted Rotors

This advanced kit builds upon the proven performance of the Procomp system by incorporating larger calipers, rotors, and brake pads, an increased number of pistons, and standard full-floating rotors that enhance self-centering capabilities within the caliper. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers are exceptionally lightweight, incredibly strong, and resistant to corrosion. The calipers also feature aluminum pistons, which offer improved heat resistance and maintain consistent operation under demanding conditions. The kit includes D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Additionally, the kit comes with SC5 Street Pads, designed for optimal braking performance on the street and for occasional track use, offering a significant reduction in brake dust, noise, and rotor wear, with an optimal operating temperature range between 194°F and 1022°F. This Supercomp Big Brake Kit features a floating two-piece rotor design, where the outer section can shift slightly, improving self-centering within the caliper. This design reduces brake drag and boosts overall performance through more even brake application. The rotors are available in either Cross Drilled or Slotted options; Cross Drilled rotors are recommended for daily-driven vehicles due to better cooling, while Slotted rotors are suggested for track-focused applications. **Fitment Information:** This kit is specifically designed for 2WD vehicles and fits the Mazda 3 from 2004-2009, excluding Mazdaspeed models.
