Description

The Ksport DualComp Big Brake Kit is a high-performance rear braking system engineered for a range of Mercedes-Benz E-Class vehicles from 2003 to 2008. This kit includes 4-piston calipers and 330mm rotors, designed to significantly upgrade your vehicle's stopping power. Buyers have the option to select between two rotor types: slotted or cross-drilled. The cross-drilled rotors are recommended for daily driving as they offer superior cooling, whereas the slotted rotors are better suited for track applications where maximum performance and heat dissipation are critical. The kit also incorporates stainless-steel brake lines, which resist expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Ksport Big Brake kits are built to order, so please anticipate a production and delivery timeframe of 4-6 weeks. It is important to note that these Ksport Big Brake kits fit 2WD vehicles only, unless explicitly stated otherwise. The manufacturer also advises that all products sold by Ksport USA are designated for Race Only and intended for competition/off-road use limited to racing sanctioned by a recognized racing organization, unless explicitly stated otherwise on the product page.
