{"product_id":"supercomp-front-big-brake-kit-400mm-x-36mm-8-piston-1","title":"Supercomp Front Big Brake Kit 400mm x 36mm 8-Piston","description":"The Ksport Supercomp Front Big Brake Kit is engineered to deliver the ultimate in stopping power for your BMW E8X 1M Coupe. This advanced braking system integrates new technology to significantly reduce brake fade and continually refresh the brake pad surface during intense braking.\n\nThe kit features a massive 400mm x 36mm rotor diameter and an 8-piston caliper configuration. The SuperComp caliper is forged from aircraft-quality billet aluminum, weighing just over 7 lbs, and includes protection grooves, aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel wear plates. The opposed piston design enhances pad wear and caliper rigidity, while stainless steel brake lines prevent expansion under pressure. Each SuperComp caliper requires four brake pads due to its size.\n\nIncluded is a 2-piece floating disc assembly designed to reduce both rotating and unsprung weight. This floating design also mitigates thermal stresses that can cause disc warping or cupping under extreme heat. The rotors feature a unique slot design that reduces braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. Cross-drilled rotors are recommended for daily drivers for cooler operation, while slotted rotors are suggested for track-focused vehicles.\n\nStandard equipment includes Ksport SC5 Street Pads, which are NAOC ceramic pads designed for optimal street and occasional track performance with a wide operating temperature range. For dedicated track use, optional Ksport RC5 Race Pads (carbon metallic) are available, though not recommended for street driving due to their higher optimal operating temperatures.\n\nIt comes with CNC-machined carbon steel caliper brackets and D.O.T. compliant stainless-steel braided brake lines for improved pedal feel and quicker response. All Ksport big brake kits include a 12-month limited warranty against manufacturer defects.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868440523064,"sku":"BKBM135-961CO","price":4586.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986202.jpg?v=1787914197","url":"https:\/\/store.motormia.co\/products\/supercomp-front-big-brake-kit-400mm-x-36mm-8-piston-1","provider":"MOTORMIA","version":"1.0","type":"link"}
