{"product_id":"4-piston-356mm-red-big-brake-kit","title":"4 Piston 356mm Red Big Brake Kit","description":"This Procomp Big Brake Kit offers a sophisticated, bolt-on upgrade for enhanced performance.\n\nThe caliper is machined from aircraft-quality billet and features a differential bore configuration. It weighs just over 5 lbs and includes protection grooves, aluminum pistons, high-temperature seals, and stainless steel wear plates. The opposed piston design improves pad wear and caliper rigidity compared to OEM systems, while stainless steel brake lines prevent expansion under pressure.\n\nThis kit utilizes a 2-piece floating disc assembly to reduce rotating and unsprung weight, and to mitigate thermal stresses from extreme heat. The unique rotor slot design minimizes braking noise and efficiently expels gas and pad debris. The cross-drilled rotors are recommended for daily driven vehicles due to their cooler operating temperatures.\n\nThis specific kit is designed for the rear application on the 1993-1995 Mazda RX-7 FD3S chassis, featuring a 356mm (14-inch) diameter rotor with a drilled finish and a red ProComp 4-piston caliper.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868607213880,"sku":"BKMZ100-443CO","price":3922.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687993912.webp?v=1787915494","url":"https:\/\/store.motormia.co\/products\/4-piston-356mm-red-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
