{"product_id":"dualcomp-rear-big-brake-kit-31","title":"Dualcomp Rear Big Brake Kit","description":"The Ksport Dualcomp Rear Big Brake Kit is engineered as an ultimate all-in-one dual caliper solution, specifically designed for the BMW F3X 3-Series Sedan models 320 and 328 (2012-2018). This kit integrates a single 4-pot caliper, with two pistons dedicated to the foot brake and the other two for the handbrake, each operating on its own independent system. This design is ideal for performance driving, including drifting and rally racing.\n\nThe caliper is constructed from a lightweight, forged one-piece billet of aerospace-quality aluminum, ensuring uniform thickness and strength to prevent fracturing or warpage. It features aluminum pistons with heavy-duty seals capable of withstanding high temperatures, ensuring smooth operation and consistent pad wear. Opposed-piston design, high-temperature seals, titanium retainer clips, and stainless-steel wear plates are standard.\n\nThe two-piece rotor design offers lightweight construction, fade-free performance, and effective grip. Lightweight center sections crafted from 6061-T6 aircraft-grade aluminum reduce rotational mass and improve brake response. The outer rotor section can expand and contract independently, reducing warping. Drilled rotors are recommended for daily drivers for cooler operation, while slotted rotors are suggested for track use.\n\nKits come standard with SC5 Street Pads, offering optimal braking performance for street and occasional track use with reduced dust and noise. An upgrade to RCI Race Pads is available for extreme track conditions. D.O.T. compliant stainless-steel braided brake lines are included, providing a firmer pedal feel and quicker response compared to stock rubber lines. The kit also features a polished titanium handbrake cylinder and lever and CNC-machined carbon steel caliper brackets for direct bolt-on installation. Various caliper color options and center bell upgrades are available.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868445438264,"sku":"BKBM250-435CO","price":2743.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687985526.jpg?v=1787914266","url":"https:\/\/store.motormia.co\/products\/dualcomp-rear-big-brake-kit-31","provider":"MOTORMIA","version":"1.0","type":"link"}
