These USC10 RC F lowering springs deliver an approximate 1.3\" front and 1.0\" rear drop with spring rates of 9 Kg\/mm front and 16 Kg\/mm rear, designed for the RC F's Adaptive Variable Suspension. Built in Japan from Swift's proprietary H5S.TW high-tensile spring steel, these RC F springs provide a lower center of gravity and reduced body roll for more confident braking zones and corner entry at track days.\u003c\/p\u003e\n\u003ch3\u003eSwift Spec-R Technology\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProprietary H5S.TW high-tensile spring steel, manufactured in Japan\u003c\/li\u003e\n\u003cli\u003eOptimized ride height to maximize suspension geometry at lowered position\u003c\/li\u003e\n\u003cli\u003eIncreased spring rates tuned to usable shock stroke for balanced performance\u003c\/li\u003e\n\u003cli\u003eFewer coils reduce unsprung mass and completely eliminate coil bind\u003c\/li\u003e\n\u003cli\u003eQuicker transient response for improved traction and road feedback\u003c\/li\u003e\n\u003cli\u003eVehicle-specific bump rubber engineering to prevent bottoming out\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTrack-proven in HPDE and SCCA competition\u003c\/li\u003e\n\u003cli\u003eLowered center of gravity for improved cornering grip\u003c\/li\u003e\n\u003cli\u003eReduced body roll and sharper handling response\u003c\/li\u003e\n\u003cli\u003eComfortable enough for daily driving\u003c\/li\u003e\n\u003cli\u003eCompatible with OEM and aftermarket shocks\/struts\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on installation with no modifications required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"table table-striped table-primary\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e4T914R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Name\u003c\/td\u003e\n\u003ctd\u003eSwift Spec-R Lowering Springs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVehicle\u003c\/td\u003e\n\u003ctd\u003e2015-2025 Lexus RC F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChassis Code\u003c\/td\u003e\n\u003ctd\u003eUSC10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Front\u003c\/td\u003e\n\u003ctd\u003e9 Kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Rear\u003c\/td\u003e\n\u003ctd\u003e16 Kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate Drop - Front\u003c\/td\u003e\n\u003ctd\u003e1.3\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate Drop - Rear\u003c\/td\u003e\n\u003ctd\u003e1.0\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNotes\u003c\/td\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eVehicle Fitment\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e2015 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2016 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2017 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2018 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2019 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2020 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2021 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2022 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2023 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2024 Lexus RC F (USC10)\u003c\/li\u003e\n\u003cli\u003e2025 Lexus RC F (USC10)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Swift Springs","offers":[{"title":"Default Title","offer_id":40185259622460,"sku":"4T914R","price":397.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0000\/2183\/products\/swift-spec-r-lowering-springs-for-2015-lexus-rc-f-usc10-4t914r-1194332105.jpg?v=1761832333","url":"https:\/\/www.springrates.com\/products\/swift-spec-r-lowering-springs-for-2015-2025-lexus-rc-f-usc10","provider":"SPRINGRATES","version":"1.0","type":"link"}
