{"product_id":"big-brake-kit-62","title":"Big Brake Kit","description":"This system integrates advanced brake technology, utilizing an extreme lightweight, one-piece caliper that is CNC machined from aircraft-quality billet aluminum. The caliper features a differential bore configuration, aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates for durability and performance. Its opposed piston design enhances pad wear and caliper rigidity compared to OEM systems.\n\nThe kit employs a 2-piece disc assembly, which contributes to reduced rotating and unsprung weight. The unique rotor slot design efficiently expels gas and pad debris, while also reducing braking noise. Rotors are heat-treated and balanced for optimal performance. Cross-drilled rotors are recommended for daily driving due to cooler operation, while slotted rotors are better suited for track use. These brake systems are designed for easy installation with minimal tools required for most applications and fit 2WD vehicles unless otherwise stated. This specific kit is designed for the BMW Z4 2009-2016 E89 model.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868447502648,"sku":"BKBM290-836CO","price":2221.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986324.webp?v=1787914298","url":"https:\/\/store.motormia.co\/products\/big-brake-kit-62","provider":"MOTORMIA","version":"1.0","type":"link"}
