This is the true-rear-coilover version for the AWD G80 M3 and G82 M4 Competition, converting the factory integrated rear damper to a true rear coilover for full rear ride-height and damping adjustment. It separates high-speed compression, low-speed compression, and rebound so the car can be dialed in for every phase of a corner.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3-way independently adjustable damping — separate high-speed compression, low-speed compression, and rebound\u003c\/li\u003e\n\u003cli\u003eExternal-reservoir mono-tube design for consistent damping under sustained track load\u003c\/li\u003e\n\u003cli\u003eTrue-rear-coilover conversion — full rear ride-height and damping adjustment\u003c\/li\u003e\n\u003cli\u003eFull-length adjustable ride height — set height independent of spring preload to preserve shock travel\u003c\/li\u003e\n\u003cli\u003eHigh-tensile SAE 9254 springs; Swift spring upgrade available\u003c\/li\u003e\n\u003cli\u003eFront camber plates included where the application allows\u003c\/li\u003e\n\u003cli\u003eFully rebuildable and serviceable; 1-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSet of 4 BC Racing ZX Series coilovers, assembled with springs\u003c\/li\u003e\n\u003cli\u003eTrue rear coilover conversion components\u003c\/li\u003e\n\u003cli\u003eExternal reservoirs with mounting brackets\u003c\/li\u003e\n\u003cli\u003eFront upper mounts \/ camber plates (application dependent)\u003c\/li\u003e\n\u003cli\u003eSpanner wrenches and damping-adjustment tools\u003c\/li\u003e\n\u003cli\u003eInstallation hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTrue-rear-coilover design — converts the factory integrated rear damper to a true rear coilover for full rear ride-height and damping adjustment\u003c\/li\u003e\n\u003cli\u003eThis vehicle uses factory electronic\/adaptive dampers — an adaptive damper (EDC) delete or bypass module is required to prevent a suspension warning light (not included)\u003c\/li\u003e\n\u003cli\u003eA professional wheel alignment is required after installation\u003c\/li\u003e\n\u003cli\u003eProfessional installation and corner-balancing are recommended; installation follows the standard BC Racing coilover procedure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eI-135-ZX\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable\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\u003eYear\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3 Competition xDrive\u003c\/td\u003e\n\u003ctd\u003eG80\u003c\/td\u003e\n\u003ctd\u003eS58 3.0L\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 Competition xDrive\u003c\/td\u003e\n\u003ctd\u003eG82\u003c\/td\u003e\n\u003ctd\u003eS58 3.0L\u003c\/td\u003e\n\u003ctd\u003e2021+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"BC Racing","offers":[{"title":"Default","offer_id":53799472759091,"sku":"I-135-ZX","price":2685.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/ZX-1_4ab50c4e-2ff1-43ce-8ce0-86ed9faaff52.jpg?v=1785961305","url":"https:\/\/x58cartel.com\/products\/bc-racing-zx-series-coilovers-bmw-m3-m4-competition-xdrive-g80-g82-awd-s58-true-rear-coilover","provider":"x58cartel","version":"1.0","type":"link"}
