Replacing the factory springs on the G14 840i xDrive Convertible lowers the center of gravity, reduces body roll and closes up the fender gap for a cleaner, more aggressive stance.\u003c\/p\u003e\n\u003cp\u003eThe progressive spring rate keeps the ride comfortable in normal driving and firms up as load increases, so the chassis stays composed when the road gets twisty. This kit lowers the front approximately 1.3\" and the rear approximately 1.25\". It is designed for cars equipped with the factory adaptive suspension.\u003c\/p\u003e\n\u003cp\u003eH\u0026amp;R springs are made from 54SiCr6 spring steel and shot-peened for long service life, so they will not settle or sag. Every spring is 100% tested before it leaves H\u0026amp;R's ISO9001-certified facility in Germany.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eApproximate front lowering: 1.3\"\u003c\/li\u003e\n\u003cli\u003eApproximate rear lowering: 1.25\"\u003c\/li\u003e\n\u003cli\u003eProgressive spring rate design\u003c\/li\u003e\n\u003cli\u003eMaterial: 54SiCr6 spring steel\u003c\/li\u003e\n\u003cli\u003eShot-peened to increase service life\u003c\/li\u003e\n\u003cli\u003eWill not settle or sag\u003c\/li\u003e\n\u003cli\u003e100% tested before leaving the production facility\u003c\/li\u003e\n\u003cli\u003eTÜV and ISO9001 certified quality assurance\u003c\/li\u003e\n\u003cli\u003eManufactured in-house by H\u0026amp;R in Germany\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eH\u0026amp;R Sport Spring set — front and rear springs\u003c\/li\u003e\n\u003cli\u003eComplete kit as supplied by H\u0026amp;R Springs; see the installation instructions for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e H\u0026amp;R Springs specifies no additional hardware for this spring kit.\u003c\/li\u003e\n\u003cli\u003eFour-wheel alignment after installation (installer-supplied service) — required any time ride height is changed.\u003c\/li\u003e\n\u003cli\u003eProfessional installation — H\u0026amp;R specifies that its springs be installed by professional suspension mechanics only.\u003c\/li\u003e\n\u003cli\u003eSpring compressor (installer-supplied tool) — required to disassemble the factory struts on a spring-only kit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/hr-springs-technical-installation-information.pdf?v=1787168924\"\u003eH\u0026amp;R Springs Technical \u0026amp; Installation Information (PDF)\u003c\/a\u003e — installation requirements, ride-height measurement procedure, bumpstop trimming table and alignment notes.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/hr-springs-warranty-and-claims.pdf?v=1787169177\"\u003eH\u0026amp;R Warranties \u0026amp; Claims (PDF)\u003c\/a\u003e — official H\u0026amp;R warranty terms, coverage periods and claim procedure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFor cars with the factory adaptive suspension.\u003c\/li\u003e\n\u003cli\u003eH\u0026amp;R uses a different part number for each 8 Series body style — this kit is for the Convertible (G14) only.\u003c\/li\u003e\n\u003cli\u003eConfirm your exact model, drivetrain and suspension type with \u003ca href=\"\/pages\/contact-us\"\u003eSpeed Logic\u003c\/a\u003e before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003e\u003cstrong\u003e28671-4\u003c\/strong\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable class=\"va-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003e840i xDrive Convertible\u003c\/td\u003e\n\u003ctd\u003eG14\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L Turbo I6\u003c\/td\u003e\n\u003ctd\u003e2020+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"H\u0026R Springs","offers":[{"title":"Default Title","offer_id":52946942230808,"sku":"28671-4","price":500.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/ba50b467fc3982e9819f221134a7cb2aL.jpg?v=1792443911","url":"https:\/\/speedlogicauto.com\/products\/h-r-sport-springs-bmw-840i-xdrive-convertible-g14-b58","provider":"SPEED LOGIC","version":"1.0","type":"link"}
