{"product_id":"procomp-4-piston-rear-big-brake-kit","title":"Procomp 4-Piston Rear Big Brake Kit","description":"The Ksport Procomp Big Brake Kit offers a significant upgrade to your Subaru Forester's braking performance, specifically for the 2003-2007 model years. This rear kit features a robust 4-piston caliper paired with a 330mm x 32mm slotted rotor, designed to enhance stopping power and reduce brake fade, especially under demanding conditions.\n\nThe caliper construction utilizes one-piece billet aluminum for a lightweight yet incredibly strong design, incorporating aluminum pistons for corrosion resistance and better heat handling. The opposed-piston caliper design optimizes pad grip and ensures more even pad wear compared to OEM systems. For enhanced performance and pedal feel, the kit includes stainless steel brake lines that prevent expansion under high temperatures and pressures.\n\nThe 2-piece rotor assembly, featuring an aluminum center, reduces rotational mass and improves braking response. The slotted rotor design is recommended for track use, as it effectively wicks away heat, dust, and gases from the pad surface. Ksport offers different pad compounds, including SC5 Street pads for daily driving and RC1 Race Pads for extreme track conditions. This kit comes with a 12-month warranty covering manufacturer defects. A fitment note specifies it is designed for vehicles with a 290mm OEM front rotor.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52865479606584,"sku":"BKSB020-433SO","price":2084.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687992069.webp?v=1787888912","url":"https:\/\/store.motormia.co\/products\/procomp-4-piston-rear-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
