Description

This sophisticated bolt-on system enhances the already impressive features of Ksport's Procomp kit by incorporating larger calipers, rotors, and brake pads, a higher piston count, and standard full-floating rotors that promote superior self-centering within the caliper. The calipers themselves are forged from a single billet of aircraft-grade aluminum, ensuring exceptional strength, light weight, and immunity to corrosion. They are equipped with aluminum pistons, which offer superior heat resistance and reliable operation under demanding conditions. Furthermore, the floating two-piece rotor design allows the outer section to shift slightly, improving self-centering, reducing brake drag, and enhancing overall braking performance through more consistent pad application. Customizable options include painted caliper colors (Orange, Red, Black, Yellow) and premium high-polish finishes (Silver, Gold, Titanium), with over 20,000 custom color finishes available. The kit comes standard with SC5 Street Pads, offering optimal performance for street and occasional track use with reduced dust and noise. D.O.T. compliant stainless-steel braided brake lines are also included, providing quicker pedal response and a firmer pedal feel by eliminating line expansion under pressure. 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 advised for track-focused vehicles. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. Please note that Ksport Big Brake kits are designed to fit 2WD vehicles only, unless explicitly stated otherwise. Fitment is confirmed for Mazda RX-8 models from 2003-2012. Fitment Industries will confirm the estimated time of arrival within 1-3 days of purchase, as this item may be backordered.
