{"product_id":"supercomp-rear-big-brake-kit-356mm-slotted-4-piston","title":"Supercomp Rear Big Brake Kit 356mm Slotted 4-Piston","description":"The Ksport Supercomp Rear Big Brake Kit is engineered to deliver unparalleled stopping power for your Mercedes Benz S210 E-Class. This advanced braking system integrates new technologies to significantly reduce brake fade and continuously cool the brake pads during operation.\n\nAt the heart of this kit is the extreme lightweight SuperComp caliper, forged from aircraft-quality billet aluminum. It features a differential bore configuration with significantly larger pistons than standard calipers, weighing just over 7 lbs. each and incorporating protection grooves for bridge tubes. Standard features include aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity compared to OEM setups, while stainless steel brake lines prevent expansion under pressure. Each caliper requires four brake pads due to its size.\n\nThe kit includes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. The floating disc design mitigates thermal stresses from extreme heat, preventing warping or cupping of the braking surface. The unique slot design on the rotor minimizes braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. Slotted rotors are recommended for track use, while cross-drilled rotors are better suited for daily driving as they tend to run cooler.\n\nThis product is made to order and is non-refundable.
