{"product_id":"supercomp-big-brake-kit-67","title":"Supercomp Big Brake Kit","description":"The Ksport Supercomp Big Brake Kit represents the pinnacle of braking performance upgrades, engineered to deliver maximum stopping power for your BMW Z4. This sophisticated, bolt-on system integrates larger calipers, rotors, and brake pads compared to Ksport's Procomp line, along with an increased piston count for superior modulation and force. The calipers are precision-machined from a single billet of aerospace-grade aluminum, ensuring exceptional strength, light weight, and resistance to corrosion. Aluminum pistons further enhance heat management for consistent performance.\n\nThis kit utilizes a floating two-piece rotor design, allowing the outer section to self-center within the caliper for reduced drag and more even pad application. The rotors are available in either slotted or cross-drilled configurations; slotted rotors are recommended for track use due to their superior heat dissipation and cleaning capabilities, while cross-drilled rotors are suggested for daily drivers. The kit includes SC5 Street Pads, formulated with NAOC Ceramic material for optimal performance in street and occasional track conditions, offering reduced dust, noise, and rotor wear with an operating temperature range of 194°F - 1022°F.\n\nComplementing the braking components are D.O.T. compliant stainless-steel braided brake lines, which mitigate line expansion under pressure for a quicker pedal response and a firmer pedal feel. Caliper brackets are CNC machined from carbon steel to ensure a direct fit onto the OEM caliper bracket locations. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. Fitment is specifically for the 2002-2008 BMW Z4 models. It is important to note that Ksport products are often designated for \"Race Only\" and \"Off Road Use Only\" unless explicitly stated otherwise. Customers should confirm legality for their specific application.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868441080120,"sku":"BKBM140-971SO","price":5266.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986212.webp?v=1787914209","url":"https:\/\/store.motormia.co\/products\/supercomp-big-brake-kit-67","provider":"MOTORMIA","version":"1.0","type":"link"}
