{"product_id":"8-piston-coilover-kit","title":"8-Piston Coilover Kit","description":"This kit is designed for performance and racing driving styles, featuring 8-piston calipers with a 400mm (15.75\") outside diameter and a minimum wheel diameter requirement of 508mm (20\").\n\nThe calipers are constructed from a solid billet of aircraft-grade aluminum, offering a lightweight yet exceptionally strong and corrosion-free design. They incorporate aluminum caliper pistons for improved heat resistance and smoother operation, along with an opposed-piston caliper design that greatly enhances pad grip and minimizes uneven wear. Reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers bolt directly onto existing mounting points without modification.\n\nThe braking performance is further enhanced by the 2-piece, slotted, vented rotors. These rotors feature an aluminum center to reduce rotational mass, leading to quicker braking response and shorter stopping distances. The 2-piece design also minimizes the chance of rotor warpage by allowing for more unrestricted expansion and contraction of the outer iron section. The outer rotor sections are made from high-carbon iron to achieve low levels of noise and vibration.\n\nAdditionally, the kit includes stainless steel brake lines that prevent expansion under high temperatures and pressures, resulting in faster pedal response. This kit is designed for a bolt-on replacement without modifications and is specifically designed for the 2015-2018 Subaru WRX STI.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868733894968,"sku":"BKSB220-961SO","price":4169.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687993043.webp?v=1787916021","url":"https:\/\/store.motormia.co\/products\/8-piston-coilover-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
