{"product_id":"spec-r-lowering-springs-7","title":"Spec-R Lowering Springs","description":"Swift Spec-R lowering springs provide a track-focused upgrade for the Nissan 370Z (2009-2020). Engineered to complement factory shocks and dampers, these springs offer stiffer rates (10 kg front, 10.5 kg rear) and a lowered stance (1.2\" front, 1.0\" rear) to maximize suspension geometry and enhance performance during spirited driving and track events.\n\nSwift's unique spring design ensures a consistent spring rate throughout the stroke, maximizes stroke length, provides high durability against height loss, and offers the lightest weight possible.\n\nThis full set of 4 springs is built for track duty and designed at the upper limits of the OEM shock valving, offering a significant improvement over stock. Customers have reported a night-and-day difference in handling, with reduced body roll and a surprisingly smooth ride, even with stock Bilstein struts. Installation is generally straightforward, but users are cautioned to use basic spring compressors, as specialized jaw-style compressors may not fit due to the spring length.","brand":"Swift","offers":[{"title":"Default Title","offer_id":52866422047032,"sku":"4N905R","price":357.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687702666.webp?v=1787907593","url":"https:\/\/store.motormia.co\/products\/spec-r-lowering-springs-7","provider":"MOTORMIA","version":"1.0","type":"link"}
