8-Piston Front Big Brake Kit w/ Slotted Rotors

Each caliper is forged from a single piece of aircraft-grade aluminum, ensuring exceptional strength, reduced weight, and superior resistance to corrosion. The opposed piston caliper design enhances pad wear and overall rigidity compared to OEM components. Inside, aluminum pistons provide better heat management. This kit features lightweight, two-piece rotors that reduce both rotating and unsprung mass. The rotors are available in either slotted or cross-drilled configurations; slotted is recommended for track use to help expel gas and debris, while cross-drilled rotors are better suited for daily driving due to their cooler operation. Included are high-performance SC5 street brake pads, designed for optimal braking in street and occasional track use, with reduced dust and noise. D.O.T. compliant stainless-steel braided brake lines are also standard, offering a firmer pedal feel and quicker response by preventing line expansion under pressure. The kit includes all necessary mounting components and hardware. Please note that Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This kit is specifically designed for the Mercedes Benz S-Class W221 chassis, model years 2006 through 2013, including the S430, S550, S600, S63 AMG, and S65 AMG variants. As with many automotive parts, this product is subject to California Proposition 65 warnings regarding potential cancer and reproductive harm.
