{"product_id":"supercomp-421mm-x-36mm-8-piston-front-big-brake-kit","title":"Supercomp 421mm x 36mm 8-Piston Front Big Brake Kit","description":"The Ksport Supercomp Big Brake Kit is engineered to deliver the ultimate in stopping power for your BMW E31 8-Series. This front brake system integrates advanced brake technology to significantly reduce brake fade and continuously cool and refresh the brake pad surface, ensuring consistent performance under demanding conditions.\n\nThe SuperComp caliper is an extreme lightweight design forged from aircraft-quality billet aluminum, weighing just over 7 lbs. It features a differential bore configuration with larger pistons than Ksport's ProComp calipers, 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, while the included stainless-steel brake lines resist expansion under pressure. Due to the caliper's size, each unit requires four brake pads.\n\nThis 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 and surface cupping. The unique slot design on the rotor helps minimize braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. The SuperComp systems come standard with Ksport SC5 Street Pads, designed for optimal performance under street and occasional track conditions with an operating temperature range of 194°F – 1022°F, offering reduced dust and noise. An option for Ksport RC5 Race Pads, suitable for extreme track conditions with higher operating temperatures, is also available.\n\nAll Ksport big brake kits include CNC-machined carbon steel caliper brackets designed specifically for your vehicle, ensuring a direct bolt-on fit to the OEM caliper location. D.O.T. compliant stainless-steel braided brake lines are standard, improving overall pedal feel and response. This product is made to order and non-refundable, with an estimated time of arrival provided once the order is submitted to the supplier.
