Description

The Ksport Procomp Rear Big Brake Kit offers a sophisticated bolt-on brake upgrade to significantly enhance stopping power, especially under sustained high-heat conditions. The calipers are constructed from a single billet of aerospace-quality aluminum, providing unparalleled strength and light weight. They feature 4-piston configurations and aluminum pistons for improved heat resistance and corrosion-free operation. The two-piece rotor design utilizes 6061-T6 aircraft-grade aluminum center sections for reduced rotational mass, leading to quicker brake response and longer service life. Rotors are available in cross-drilled or slotted options, with cross-drilled recommended for daily drivers for cooler operation and slotted for track use. This kit includes replacement calipers, 356mm (14-inch) diameter rotors with a 32mm width, brake pads (with options for street or race), stainless steel braided brake lines, and all necessary hardware. Center bell customization options, including titanium or twin-color anodized bells, are available to further personalize the system. Caliper color options range from standard finishes like Orange, Red, Black, and Yellow to premium high-polish and custom color choices. Ksport Big Brake Kits are made-to-order and are non-refundable. The kit is specifically designed for the Mercedes Benz W204 C-Class 4Matic models, including the C300 and C350, from 2007-2013.
