{"product_id":"big-brake-kit-with-differential-bore-calipers-and-two-piece","title":"Big Brake Kit with Differential Bore Calipers and Two-Piece","description":"The kit features an extremely lightweight, one-piece caliper, CNC machined from aircraft quality billet aluminum. This caliper boasts a differential bore configuration, aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates, and weighs just over 5 lbs. Its opposed piston design enhances pad wear and caliper rigidity compared to OEM systems.\n\nThe kit utilizes a two-piece disc assembly, significantly reducing both rotating and unsprung weight. For applications experiencing extreme heat, a floating disc option is available to prevent thermal stress-induced warping of the disc or braking surface. Ksport's unique rotor slot design is optimized to minimize braking noise while efficiently expelling gases and pad debris for consistent performance. Rotors are heat-treated and balanced to ensure optimal performance, with options for cross-drilled rotors (cooler, recommended for daily driving) or slotted rotors (recommended for track use).\n\nStainless-steel brake lines are included to prevent expansion under pressure, ensuring a firm pedal feel. The Supercomp Big Brake Kit is specifically designed for the 1989-1994 Nissan 240SX S13 models with a 5x114.3 bolt pattern.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868665770296,"sku":"BKNS211-446SO","price":2605.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687993393.webp?v=1787915714","url":"https:\/\/store.motormia.co\/products\/big-brake-kit-with-differential-bore-calipers-and-two-piece","provider":"MOTORMIA","version":"1.0","type":"link"}
