{"product_id":"procomp-13-inch-32mm-rotor-4-piston-caliper-big-brake-kit","title":"Procomp 13-Inch 32mm Rotor 4-Piston Caliper Big Brake Kit","description":"The Ksport Procomp Big Brake Kit offers a significant upgrade in stopping power for your BMW 3 Series E30 (1982-1992). The calipers are CNC machined from aircraft-quality billet aluminum, featuring a one-piece construction for lightweight strength, an opposed-piston design for improved pad wear and rigidity, aluminum pistons for corrosion resistance and lighter weight, and high-temperature seals. The kit includes stainless steel brake lines to prevent expansion under pressure for quicker pedal response.\n\nThe 2-piece disc assembly is designed to reduce rotating and unsprung weight. Many applications offer a floating disc option to mitigate warping caused by thermal stresses. The unique slot design on the rotor helps reduce braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. For street use, Ksport recommends the SC5 Street pads with a low-dust ceramic compound, while RC1 Race Pads are suggested for track use due to their carbon metallic compound for maximum stopping power under extreme conditions. This specific kit features a fixed rotor type, a 13-inch diameter, 32mm width, and 4-piston calipers, with a standard orange caliper color, and is intended for the rear position.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868427252024,"sku":"BKBM010-433SO","price":2293.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687985980.webp?v=1787914034","url":"https:\/\/store.motormia.co\/products\/procomp-13-inch-32mm-rotor-4-piston-caliper-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
