Procomp Rear Big Brake Kit

The Ksport Procomp Rear Big Brake Kit provides the ultimate in stopping power for your BMW E46 3-Series (1999-2005 models, excluding 330 and xi variants). The kit includes replacement calipers, rotors, pads, brake lines, and associated hardware for a comprehensive solution. Constructed from aerospace-quality aluminum, the one-piece forged calipers are exceptionally lightweight yet incredibly strong, eliminating weak spots common in cast or welded designs. Opposed-piston design ensures consistent brake pad wear, while aluminum pistons with heavy-duty seals handle high temperatures effectively. The two-piece rotor design, also lightweight, is crafted from 6061-T6 aircraft-grade aluminum for reduced rotational mass and improved heat dissipation, minimizing warping potential. This kit offers customization options, including caliper color choices (standard and premium finishes), pad selection (Street or Race), and optional upgrades like a Titanium Center Bell and Hardware. It includes SC5 Street Pads as standard, with an option to upgrade to RCI Race Pads for extreme track conditions. The kit also features D.O.T. compliant stainless-steel braided brake lines, which enhance pedal response and feel compared to stock rubber lines. It is important to note that Ksport Big Brake Kits are made-to-order and non-refundable. The Ksport Procomp Big Brake kits fit 2WD vehicles only and specifically exclude 330 and xi models for the BMW 3 Series E46 (1999-2005).
