Supercomp Rear Big Brake Kit 356x32mm

The Ksport Supercomp Rear Big Brake Kit is engineered to provide superior stopping power for your Mercedes Benz W212 E63 AMG, significantly reducing brake fade and enhancing brake cooling. This kit integrates advanced brake technology, ensuring consistent performance even under demanding conditions. The SuperComp caliper is a standout feature, forged from aircraft-quality billet aluminum for extreme lightness, weighing just over 7lbs each. It boasts a differential bore configuration with substantially larger pistons than Ksport's ProComp calipers. Standard inclusions are aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston caliper design significantly improves pad wear and caliper rigidity compared to OEM components, while the stainless-steel braided brake lines prevent expansion under pressure, leading to a firmer pedal feel and quicker response. The kit features Ksport's 2-piece floating disc assembly, which reduces both rotating and unsprung weight. This floating design mitigates thermal stresses from extreme heat, preventing rotor warping or cupping. The rotors are equipped with a unique slot design that minimizes braking noise and efficiently expels gas and pad debris. Standard on this kit are cross-drilled rotors, which tend to run cooler and are recommended for daily driven vehicles, while slotted rotors are available for more track-focused applications. This kit includes Ksport SC5 Street Pads, which are NAOC ceramic pads designed for optimal street and occasional track performance, with optimal operating temperatures between 194°F – 1022°F. These pads reduce brake dust by over 50% and minimize noise and rotor wear. For those seeking maximum track performance, Race Pads (RC5 carbon metallic) are available as an option. The SuperComp kits are made to order, and due to their custom nature, are non-refundable. Compatibility is specifically for the Mercedes Benz E Class W212 (2010-2016) E63 AMG M156 6.3L (2010-11) and E63 AMG 4-Matic M157 5.5TT (2012-17).
