This comprehensive kit includes a 380x32mm two-piece floating disc assembly and a lightweight, yet robust, SuperComp caliper. Forged from aircraft-quality billet aluminum, the caliper boasts a differential bore configuration with larger pistons than Ksport's ProComp calipers, weighing just over 7lbs and featuring machined protection grooves. Standard components include aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston caliper design significantly improves pad wear and caliper rigidity, while the stainless-steel braided brake lines ensure a firm pedal by preventing expansion under pressure.\n\nThe two-piece floating disc assembly is crucial for reducing both rotating and unsprung weight, and it effectively dissipates thermal stresses that can lead to disc warping or surface cupping under extreme heat. The rotors feature a unique slot design that minimizes braking noise and efficiently expels gas and pad debris. Ksport provides options for both cross-drilled rotors, recommended for daily drivers due to their cooler operation, and slotted rotors, preferred for track applications. Standard on this kit are Ksport SC5 Street Pads, made from NAOC ceramic, designed for optimal street and occasional track performance with temperatures between 194°F – 1022°F. These pads offer a significant reduction in brake dust and rotor wear compared to race pads.\n\nCustomization options are available for this made-to-order kit, including a selection of caliper colors such as Ksport Orange, Race Red, Caution Yellow, Jet Black, Bold Blue, and premium finishes like Lightning Silver, High Silver Polish, High Gold Polish, Titanium, Glassy Green, Glassy Blue, Glassy Orange, Glassy Red, Glassy Black, and Hard Anodized Black, some of which incur additional charges. Buyers can also choose between Street Pads (standard) and Race Pads, and select various Center Bell Upgrades, including Titanium and Twin Color Anodized options. It is important to note that Ksport Big Brake Kits are made-to-order and non-refundable once the order is placed. The kit is specifically designed for the BMW 1 Series E82\/E88 models from 2008-2013, fitting the 135i with N54 3.0L or N55 3.0L engines, as well as the 128i with the N52 3.0L engine.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868439867704,"sku":"BKBM130-653CO","price":3869.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687983839.jpg?v=1787914188","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-380x32mm-2-piece-floating-disc-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
