{"product_id":"b9-a4-s4-lowering-spring-set","title":"B9 A4\/S4 Lowering Spring Set","description":"This ECS Tuning Lowering Spring Set is engineered for the B9 A4 and S4 models, offering an average lowering range of 1.0\" to 1.5\" for both front and rear. This adjustment significantly lowers the vehicle's center of gravity, which translates to improved cornering performance and more precise steering feedback. Beyond the performance benefits, the springs provide a notable aesthetic upgrade by reducing wheel gap, giving the car a sportier, more aggressive stance.\n\nKey features include a \"Made in the USA\" designation, specific front spring rates of 374 lbs\/in and rear rates of 315 lbs\/in, and dual-rate springs with pigtail ends for proper fitment. The springs are finished with a black powder coating and feature a red ECS logo for durability and style. These springs were developed and tested in-house by ECS Tuning's Research \u0026amp; Development team to ensure high precision and quality.\n\nFor an even more aggressive look and driving experience, ECS Tuning suggests considering an ECS Flush Kit or wheel spacer sets to widen the track width. To complete the installation, the ECS Tuning cup kit\/Coilover Installation Kit (ES#3691724) is recommended.\n\nThis product fits the following vehicles: Audi B9 A4 FWD 2.0T, Audi B9 A4 Quattro 2.0T, and Audi B9 S4 Quattro 3.0T. Always use the vehicle selector to confirm exact fitment.","brand":"ECS Tuning","offers":[{"title":"Default Title","offer_id":52662772203832,"sku":"051204LA01-A","price":284.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687496630.jpg?v=1784320795","url":"https:\/\/store.motormia.co\/products\/b9-a4-s4-lowering-spring-set","provider":"MOTORMIA","version":"1.0","type":"link"}
