{"product_id":"6-piston-big-brake-kit-with-slotted-rotors-12","title":"6-Piston Big Brake Kit with Slotted Rotors","description":"The Ksport ProComp Big Brake Kit offers a sophisticated bolt-on brake upgrade for 2015-2018 Subaru WRX STI models, engineered to significantly enhance braking performance, especially under sustained high-heat conditions. This kit is ideal for performance and racing driving styles, aiming to reduce brake fade and improve stopping distances.\n\nThe kit features robust 6-piston calipers, precisely machined from a solid billet of aircraft-grade aluminum. This construction ensures both lightweight design and unparalleled strength, while aluminum caliper pistons offer superior heat resistance and are resistant to corrosion. The calipers are complemented by 2-piece, vented, and slotted rotors made from cast iron with aluminum centers. This design reduces rotational mass, quickens braking response, and minimizes the chance of rotor warpage due to less restricted expansion and contraction.\n\nReinforced carbon steel caliper brackets allow the larger-than-OEM calipers to mount directly to existing points. The kit also includes heavy-duty caliper seals for sustained high-temperature racetrack use and stainless steel brake lines, which prevent expansion under high temperatures and pressures for a more immediate pedal response. For street use, the included Street pads feature a long-lasting, low-dust ceramic compound, while the slotted rotors are recommended for track applications to help dissipate heat, dust, and gases.\n\nKey specifications include a 6-piston caliper type, 380mm (15-inch) outside rotor diameter, and a requirement for a minimum 19-inch wheel diameter.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868732748088,"sku":"BKSB220-653SO","price":3675.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687993041.webp?v=1787916019","url":"https:\/\/store.motormia.co\/products\/6-piston-big-brake-kit-with-slotted-rotors-12","provider":"MOTORMIA","version":"1.0","type":"link"}
