8-Piston Big Brake Kit

The Ksport Procomp 8-Piston Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to significantly enhance brake power, particularly under sustained high-heat conditions. The kit features lightweight, forged one-piece calipers constructed from aircraft-grade aluminum, providing unparalleled strength and resistance to corrosion. These calipers house aluminum pistons, which offer superior heat resistance and maintain uncompromised operation. Key components include 356mm two-piece slotted rotors that offer lightweight construction, fade-free performance, and effective grip, ensuring comfortable operation during normal driving. The kit comes standard with NAOC Ceramic SC5 Street Pads, optimized for street use and occasional track conditions, providing a 50% reduction in brake dust and less noise and rotor wear compared to race pads. The optimal operating temperature for these pads is between 194°F - 1022°F. Further enhancing performance and feel, the kit includes D.O.T. compliant stainless-steel braided brake lines. These lines prevent hose expansion under pressure, leading to quicker pedal response and a firmer pedal feel compared to stock rubber lines. The calipers themselves are designed with an opposed piston configuration, which greatly improves pad wear and caliper rigidity over OEM designs. Caliper brackets are CNC machined from carbon steel, allowing the larger calipers to bolt directly into the OEM caliper bracket location. The kit is built to order, with production and delivery typically taking 4-6 weeks. This specific Procomp Big Brake Kit is compatible with BMW 7 Series models from 2002 to 2008, including variants such as the 745i, 750i, 750Li, 760i, and 760Li. If fitment is confirmed by Ksport's sales team and the product does not fit, the company will facilitate a return with no restocking fees, provided the item remains in like-new condition.
