{"product_id":"9-inch-swift-coilover-springs-65mm-id","title":"9-Inch Swift Coilover Springs 65mm ID","description":"Sold in pairs, these springs measure 9 inches in length and have a 65mm inner diameter, making them compatible with a wide range of aftermarket coilover systems, including those from K-Tuned Suspension, BC Racing, Cusco, D2 Racing, and many others.\n\nSwift springs are renowned for their ability to improve ride quality and allow for precise tuning of your coilovers' spring rates. While most coilover brands suggest staying within 2-4K of the original spring rates for optimal damper performance, Silver's kits can typically accommodate a 4K difference without issue. This flexibility allows you to tailor your vehicle's handling characteristics to your specific driving needs, whether for daily driving or track use.\n\nWhen selecting new spring rates, it's important to consider the original rates for your coilovers. Deviating too far from the intended rates can impact damper performance. If you are unsure about the correct spring size or rate for your specific Silver's kit or other coilover system, it is recommended to consult the manufacturer or measure your existing springs. This product is designed as a direct replacement or rate change for existing coilover setups, offering a top-tier solution for suspension enthusiasts.","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":52869727617336,"sku":"Z65-228-040","price":238.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/688004397.webp?v=1787917954","url":"https:\/\/store.motormia.co\/products\/9-inch-swift-coilover-springs-65mm-id","provider":"MOTORMIA","version":"1.0","type":"link"}
