The stock rubber bushing is a significant source of rear-end compliance — under cornering load it deflects, allowing unwanted camber and toe change. The spherical replacement locks the geometry down for sharper, more predictable rear grip.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSpherical bearing replaces the factory rubber knuckle bushing\u003c\/li\u003e\n\u003cli\u003eEliminates rear lower control arm deflection under load\u003c\/li\u003e\n\u003cli\u003eReduces unwanted camber and toe change while cornering\u003c\/li\u003e\n\u003cli\u003eWide chassis compatibility across BMW rear-suspension platforms\u003c\/li\u003e\n\u003cli\u003eDesigned and built in the USA\u003c\/li\u003e\n\u003cli\u003eSold as a set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x set of SPL rear lower control arm knuckle bushings with hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eA professional wheel alignment is required after installation\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003ePairs with our \u003ca href=\"\/products\/spl-parts-rear-upper-arms-bmw-m2-m3-m4-g87-g80-g82-g83\"\u003eRear Upper Arms\u003c\/a\u003e, \u003ca href=\"\/products\/spl-parts-rear-adjustable-traction-links-bmw-m2-m3-m4-g87-g80-g82-g83\"\u003eRear Traction Links\u003c\/a\u003e, and \u003ca href=\"\/products\/spl-parts-rear-toe-links-eccentric-lockouts-toyota-supra-bmw-z4-g2x-g42\"\u003eRear Toe Links\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eSpherical bearings transmit more noise and vibration than rubber bushings — expected on a performance component\u003c\/li\u003e\n\u003cli\u003eProfessional installation recommended — bushing replacement requires a press\u003c\/li\u003e\n\u003cli\u003eInstallation instructions (PDF): \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/SPL-RLCB-E9X-Rev-B.pdf?v=1785874995\"\u003eSPL RLCB E9X Install Guide\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSPL RLCB E9X\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse: collapse; width: 100%; text-align: left;\"\u003e\n\u003cthead\u003e\n\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\u003eYear\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM2\u003c\/td\u003e\n\u003ctd\u003eG87\u003c\/td\u003e\n\u003ctd\u003eS58\u003c\/td\u003e\n\u003ctd\u003e2023+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3 \/ M3 Competition\u003c\/td\u003e\n\u003ctd\u003eG80\u003c\/td\u003e\n\u003ctd\u003eS58\u003c\/td\u003e\n\u003ctd\u003e2021+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4 \/ M4 Competition\u003c\/td\u003e\n\u003ctd\u003eG82 \/ G83\u003c\/td\u003e\n\u003ctd\u003eS58\u003c\/td\u003e\n\u003ctd\u003e2021+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"SPL Parts","offers":[{"title":"Default Title","offer_id":53793900658995,"sku":"SPL RLCB E9X","price":152.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/d7ab67e040f1850a175810f4468f38d6M.jpg?v=1785876342","url":"https:\/\/x58cartel.com\/products\/spl-parts-rear-spherical-lower-control-arm-knuckle-bushings-bmw-m2-m3-m4-g87-g80-g82-g83","provider":"x58cartel","version":"1.0","type":"link"}
