{"product_id":"dualcomp-4-piston-big-brake-kit-6","title":"DualComp 4-Piston Big Brake Kit","description":"The KSport DualComp Big Brake Kit is engineered for performance enthusiasts looking to significantly upgrade their braking capabilities on 2015-2018 Subaru WRX STI models. This kit offers a unique DualComp system, utilizing a single 4-piston caliper that cleverly separates functions: two pistons engage for the primary foot brake, while the other two operate independently for the handbrake system.\n\nThis complete bolt-on system includes everything necessary for installation without requiring modifications. Components feature a 4-piston caliper design for improved pad grip and reduced uneven wear. The calipers utilize aluminum pistons for corrosion resistance, heat tolerance, and lighter weight. Reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers mount directly to factory points. The rotors are a 2-piece design with an aluminum center, reducing rotational mass for quicker response and shorter stopping distances, while also minimizing the chance of warpage.\n\nKey features include 356mm (14\") slotted, vented rotors, a 2-piece construction, fixed hat construction, and street performance brake pads. The minimum required wheel diameter is 457mm (18\"). All caliper seals are heavy-duty for high-temperature racetrack use, and stainless steel brake lines prevent expansion under pressure for faster pedal response.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868732584248,"sku":"BKSB220-445SO","price":3127.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687991589.webp?v=1787916018","url":"https:\/\/store.motormia.co\/products\/dualcomp-4-piston-big-brake-kit-6","provider":"MOTORMIA","version":"1.0","type":"link"}
