Description

This rear brake kit features a lightweight, 4-piston ProComp caliper, machined from aircraft-quality billet and finished in red. The caliper design enhances pad wear and rigidity over OEM systems. The kit includes 330mm (13in) diameter rotors with a drilled surface, which helps to run cooler and is recommended for daily driven vehicles. The 2-piece floating disc assembly reduces rotating and unsprung weight, while also mitigating thermal stresses that can cause warping. Stainless steel brake lines are included to prevent expansion under pressure. This specific kit is designed for the 2003-2008 Mercedes-Benz E55 AMG W211 Chassis and the 2003-2008 Mercedes-Benz E63 AMG W211 Chassis. Ksport's big brake kits integrate advanced brake technology to provide a significant upgrade over stock braking systems, ensuring reliable performance under demanding conditions.
