Supercomp Big Brake Kit Rear 4-Piston Caliper

The Ksport Supercomp Rear Big Brake Kit is engineered to deliver superior stopping power for your Mercedes-Benz C209 CLK. This kit features a robust 330mm rotor with a 32mm thickness and is equipped with a high-performance Supercomp 4-piston caliper. The advanced brake technology integrated into this kit effectively reduces brake fade and ensures the brake pads remain optimally cooled and refreshed during demanding use. The caliper itself is a standout component, forged from aircraft-quality billet aluminum. It boasts a lightweight design, weighing just over 7 lbs, and features a differential bore configuration with significantly larger pistons than standard ProComp calipers. The opposed piston design enhances caliper rigidity and improves pad wear. For further performance gains, the kit includes stainless steel braided brake lines, which minimize line expansion under pressure and contribute to a more responsive pedal feel. This kit utilizes a 2-piece floating disc assembly, which not only reduces both rotating and unsprung weight but also combats thermal stresses that can lead to disc warping or cupping. The unique slot design on the rotors assists in reducing braking noise and efficiently expels gas and pad debris. Ksport offers both cross-drilled rotors, recommended for daily driven vehicles due to cooler operation, and slotted rotors, preferred for track use. Standard with the kit are Ksport SC5 Street Pads, which are formulated for optimal performance in street and occasional track conditions. These NAOC ceramic pads operate efficiently between 194°F – 1022°F, produce significantly less dust than race pads, and minimize rotor wear and noise. For those seeking maximum track performance, Ksport RC5 Race Pads (carbon metallic) are available as an upgrade, though they require higher operating temperatures (482°F – 1472°F) and are not recommended for street use. This Ksport Big Brake Kit is a made-to-order item and is non-refundable. Please note that this specific kit is designed for the Mercedes-Benz C209 CLK models.
