This version is listed for RWD models.\u003c\/p\u003e\n\u003ch3\u003eWhat you get\u003c\/h3\u003e\u003cp\u003eExpect true coilovers at the front and a divorced rear, where the spring and damper sit in separate locations as they do from the factory. Damper bodies are 52mm front and 46mm rear. It comes with 8 kg\/mm (about 448 lb\/in) springs up front and 9.5 kg\/mm (about 532 lb\/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick. The front top mounts are aluminum with rubber bushings, with aluminum camber plates with pillowball bushings available as an option.\u003c\/p\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMonotube damper design for better heat control and fewer leaks\u003c\/li\u003e\n\u003cli\u003e32-level damping adjustment, rebound and compression combined on one adjuster\u003c\/li\u003e\n\u003cli\u003eIndependent lower mount adjustment keeps spring preload and damper travel where they should be when you change height\u003c\/li\u003e\n\u003cli\u003eT6-6061 aluminum hardware (top mounts, perches and collars), anodized against corrosion\u003c\/li\u003e\n\u003cli\u003eZinc-plated shock bodies for rust protection\u003c\/li\u003e\n\u003cli\u003eSAE9254 cold-wound springs\u003c\/li\u003e\n\u003cli\u003eNOK seals and Italian IP damping oil\u003c\/li\u003e\n\u003cli\u003eBuilt-in dust boots and bump stops\u003c\/li\u003e\n\u003cli\u003eBolt-on install with no modifications, unless the notes below say otherwise\u003c\/li\u003e\n\u003cli\u003eAdjustable ride height, roughly 1 to 2.5 inches below factory per SF Racing, while keeping suspension travel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho it suits\u003c\/h3\u003e\u003cp\u003eA good fit if the car is driven on the street most of the time and you want a lower stance with better body control.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSF-BM07-04-SP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVehicle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2009-2016 BMW Z4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eE89\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDrivetrain\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRWD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamper model\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSport Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamping\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1-Way: Rebound and Compression\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamper size (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e52mm diameter \/ 46mm diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpring rate (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 kg\/mm \/ 9.5 kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDesign (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTrue Coilover \/ Divorced (Separate shock and spring)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTop mounts (front)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStandard: Aluminum with Rubber Bushings \/ Optional: Aluminum Camber Plates with Pillowball Bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTop mounts (rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNot Applicable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"SPRINGRATES®","offers":[{"title":"Default Title","offer_id":67656228569389,"sku":"SF-BM07-04-SP","price":995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/8295\/1469\/files\/sf-racing-sport-coilovers-for-2009-2016-bmw-z4-e89-sf-bm07-04-sp-1194300597.jpg?v=1792165445","url":"https:\/\/lowerhq.com\/products\/sf-racing-sport-coilovers-for-2009-2016-bmw-z4-e89","provider":"LowerHQ","version":"1.0","type":"link"}
