{"product_id":"356mm-rear-big-brake-kit","title":"356mm Rear Big Brake Kit","description":"The Ksport Supercomp Rear Big Brake Kit is engineered to deliver superior stopping power for your BMW E30 3-Series. This kit features a substantial 356mm x 32mm two-piece floating disc assembly, designed to reduce both rotating and unsprung weight while resisting thermal stress and warping. The unique slot design on the rotor helps expel gas and pad debris, while cross-drilled rotors offer cooler running temperatures, making them suitable for daily driven vehicles.\n\nThe SuperComp caliper is forged from aircraft-quality billet aluminum and features a differential bore configuration with larger pistons than Ksport's ProComp calipers. It includes aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity, while stainless-steel brake lines prevent expansion under pressure, improving pedal feel and response. This kit comes standard with Ksport SC5 Street Pads, which offer optimal braking performance under street and occasional track conditions, reducing brake dust and noise. Alternatively, Race Pads are available for extreme track conditions.\n\nThis product is made to order, with an estimated delivery time provided after order submission. Ksport offers a 12-month limited warranty covering manufacturer defects.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868427415864,"sku":"BKBM010-447CO","price":3047.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687983631.jpg?v=1787914036","url":"https:\/\/store.motormia.co\/products\/356mm-rear-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
