8-Piston Big Brake Kit with 400mm Rotors

This front brake system integrates advanced brake technology to significantly reduce brake fade and ensure continuous cooling of the brake pads. At the core of this kit are the extreme lightweight SuperComp calipers, forged from aircraft-quality billet aluminum. These calipers feature a differential bore configuration with much larger pistons than standard OEM designs, offering enhanced rigidity and improved pad wear. Standard features include aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston design is complemented by stainless-steel braided brake lines, which improve pedal feel and response by eliminating line expansion under pressure. The kit includes 2-piece floating disc assemblies, which reduce rotating and unsprung weight while preventing thermal stresses from warping the discs. Customers can choose between cross-drilled rotors, recommended for daily driving and offering cooler operation, or slotted rotors, better suited for track applications. Both rotor types enhance "bite" and continuously clean the pad surface. Standard equipment includes Ksport SC5 Street Pads, designed for optimal performance in street and occasional track conditions with reduced dust and noise. For more extreme track use, optional Ksport RC5 Race Pads (carbon metallic) are available. The kit comes with CNC-machined carbon steel caliper brackets for straightforward installation and a 12-month limited warranty against manufacturer defects. This specific kit (BKMD081-961CO) is designed for the Mercedes-Benz W211 E55 AMG and E63 AMG models from 2003-2009. Please note that this product is made to order and is non-refundable.
