Procomp 6-Piston Front Big Brake Kit

The calipers are constructed from a 1-piece billet of aircraft-grade aluminum, offering exceptional strength, light weight, and corrosion resistance. They feature aluminum pistons for superior heat resistance and uncompromised performance. This kit utilizes CNC-machined carbon steel caliper brackets to ensure a direct fit to your vehicle's OEM caliper bracket location. The included NAOC Ceramic SC5 Street Pads offer optimal braking for street and occasional track use, reducing brake dust and noise while operating effectively between 194°F and 1022°F. D.O.T. compliant stainless-steel braided brake lines are standard, preventing expansion under pressure for quicker pedal response and a firmer pedal feel. Ksport offers flexible caliper configurations: 6-piston calipers are standard on 11" and 12" front kits, while 8-piston calipers are standard on 13" and 14" front kits. Rear kits come with 2-piston or 4-piston lightweight aluminum calipers. Customers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily drivers due to cooler running temperatures, while slotted rotors are suggested for track use. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This specific kit is designed for 2WD vehicles only. Fitment is confirmed for BMW 3 Series models from 1999-2005, including 330i, 330Ci, and 330xi trims.
