Description

This front brake system integrates advanced technology to significantly reduce brake fade and continuously cool the brake pads, ensuring consistent performance even under demanding conditions. The kit features a lightweight SuperComp caliper, forged from aircraft-quality billet aluminum, which boasts larger pistons and an opposed-piston design for improved pad wear and caliper rigidity over OEM systems. The 2-piece floating disc assembly is designed to reduce both rotating and unsprung weight, while also mitigating thermal stresses that can lead to disc warping. The unique slot design on the rotor helps to expel gas and debris, and cross-drilled rotors are recommended for daily driven vehicles for cooler operation. Standard equipment includes D.O.T. compliant stainless-steel braided brake lines for improved pedal feel and quicker response. This specific kit, the BKMD300-971CO, is tailored for the Mercedes Benz W205 C300 (2015-2021) with the M274 2.0L engine. It is a made-to-order item and is non-refundable once ordered. Options for caliper color, pad type (Street or Race), and center bell upgrades are available, allowing for customization to suit your needs. Note that this product is intended for the specified Mercedes Benz W205 C300 and may not be compatible with other vehicle configurations.
