Wrong! When UMI chose to manufacture our own line of springs we went all out.  Designed in conjunction with a leading Sprint Cup chassis engineer, these  springs are the best in the business. Our springs are wound from 5160 CrSi premium  wire and feature a linear 600 lb\/in rate. UMI’s front springs are stiffer than  stock to provide increased performance with decreased body roll and a lower  center of gravity. These springs are suitable for Auto-x and Pro-Tour  applications as well as corner carving\/cruising.","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":40702005772370,"sku":"UMI3050F","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/4256\/2386\/products\/41670a7e3aadf5267fb8f34a14029686.jpg?v=1706516564","url":"https:\/\/www.vinniebuilt.net\/products\/umi-performance-78-88-gm-g-body-front-1in-70-81-f-body-2-1-2in-lowering-spring","provider":"VINNIEBUILT","version":"1.0","type":"link"}
