{"product_id":"progressive-lowering-springs-4","title":"Progressive Lowering Springs","description":"The Integrated Engineering lowering springs are meticulously engineered to correct the factory 'lifted' look of your Audi B9\/B9.5 A4 or S4, providing a flush and aggressive fender-to-tire fitment. The design eliminates factory reverse rake while maintaining functional clearance for everyday driving. Constructed from High-Tensile Chrome Silicon Spring Steel, these springs utilize a progressive rate design that remains compliant over road imperfections before stiffening under load, ensuring confident body control without harshness.\n\nThese performance springs feature carefully tuned rates to keep the chassis flat through high-G corners, enhancing grip and reducing body roll. By rebalancing the front-to-rear spring rates, turn-in is sharpened, understeer is reduced, and squat and dive are minimized.\n\nThe specific drop varies by model: A4 S-Line receives approximately a ½ Inch front and 1 ¼ Inch rear drop, A4 models get a 1 ⅛ Inch front and 1 ¼ Inch rear drop, and S4 models feature a 1 ⅛ Inch front and ⅞ Rear drop. The spring rates are 558 lbf\/in for the front and 515 lbf\/in for the rear.\n\nThese lowering springs are compatible with the following Audi models: 2017-2020 A4 2.0T FWD, 2017-2025 A4 2.0T AWD, and 2018-2025 S4 3.0T AWD.","brand":"Integrated Engineering","offers":[{"title":"Default Title","offer_id":52664236835128,"sku":"IESSCK2","price":324.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687724050.jpg?v=1784335695","url":"https:\/\/store.motormia.co\/products\/progressive-lowering-springs-4","provider":"MOTORMIA","version":"1.0","type":"link"}
