{"product_id":"lowering-spring-set-5kgf-front-7-5kgf-rear","title":"Lowering Spring Set, 5kgf Front \/ 7.5kgf Rear","description":"The Swift Sport Lowering Spring Set, part number 4T911, is engineered for the 2013 and newer Lexus GS350 GRL10 models. This set provides a modest yet effective lowering of approximately -0.8 inches at both the front and rear, achieving a more aggressive stance.\n\nThese springs are precision-tuned with specific rates: 5kgf for the front and 7.5kgf for the rear. The manufacturer emphasizes that Swift is the only lowering spring brand they wholeheartedly recommend due to their commitment to proper R\u0026amp;D. This ensures that the factory stroke and damping force are accurately measured and not exceeded, preventing common issues like blown shocks, bottoming out, harsh ride quality, bouncing, and oscillation.\n\nUnlike many aftermarket lowering springs that compromise ride quality, handling, and OEM damper longevity, Swift's approach focuses on optimizing ride height, spring rate, stroke, and progression.","brand":"Swift","offers":[{"title":"Default Title","offer_id":52872159789368,"sku":"4T911","price":477.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/lowering-spring-set-5kgf-front-7-5kgf-rear","provider":"MOTORMIA","version":"1.0","type":"link"}
