Description

The Ksport Slimline 3-Piston Big Brake Kit is engineered to provide a significant upgrade in braking performance for your Mercedes-Benz C-Class (W203 chassis, 2000-2007 models). This kit includes 350mm slotted rotors and 3-piston calipers, designed to offer improved stopping power and a more responsive pedal feel compared to stock systems. Ksport developed the Slimline caliper with a unique single-side piston design, mimicking the thickness of OEM calipers. This innovation ensures compatibility with a wider range of factory wheels and aftermarket wheels that have limited clearance, addressing a common issue with larger big brake kits. Included in the kit are SC5 Street Pads, formulated to deliver excellent braking performance for daily driving and occasional track use. These pads offer a substantial reduction in brake dust (over 50%) and noise compared to race pads, while also minimizing rotor wear. The operating temperature range for these pads is between 194°F and 1022°F. Further enhancing the system are D.O.T. compliant stainless-steel braided brake lines. These lines replace stock rubber lines, preventing expansion under pressure for a firmer pedal and quicker response. The calipers are available in various standard colors like Orange, Red, Black, and Yellow, with options for premium finishes and custom colors. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks.
