This version is listed for RWD models.\u003c\/p\u003e\n\u003ch3\u003eHow this kit is set up for the 2007-2013 Mercedes-Benz S65 AMG RWD (W221)\u003c\/h3\u003e\u003cp\u003eIt is a true coilover at all four corners, so the spring and damper work as one unit front and rear. Damper bodies are 52mm front and 50mm rear. It comes with 12 kg\/mm (about 672 lb\/in) springs up front and 8 kg\/mm (about 448 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. At the rear, the mounts are aluminum with rubber bushings.\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 damping settings on a single knob that sets rebound and compression together\u003c\/li\u003e\n\u003cli\u003eCold-wound SAE9254 spring steel\u003c\/li\u003e\n\u003cli\u003eNOK seals and Italian IP damping oil (20W)\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\u003eRide height lowers roughly 1 to 2.5 inches below stock (SF Racing's figure) without giving up suspension travel\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\u003c\/ul\u003e\n\u003ch3\u003eWho it suits\u003c\/h3\u003e\u003cp\u003eA good fit for dual-duty cars that commute during the week and hit the track on weekends.\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-MB14-06-TR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVehicle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2007-2013 Mercedes-Benz S65 AMG RWD (W221)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eW221\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\u003eTrack 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 \/ 50mm 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\u003e12 kg\/mm \/ 8 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 \/ True Coilover\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\u003eAluminum with Rubber 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\u003eAluminum with Rubber Bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"SPRINGRATES®","offers":[{"title":"Front: 12K \/ Rear: 8K","offer_id":67656330117421,"sku":"SF-MB14-06-TR","price":1195.0,"currency_code":"USD","in_stock":true},{"title":"Front: 12K \/ Rear: 10K","offer_id":67656330150189,"sku":"SF-MB14-06-TR","price":1195.0,"currency_code":"USD","in_stock":true},{"title":"Front: 14K \/ Rear: 8K","offer_id":67656330182957,"sku":"SF-MB14-06-TR","price":1195.0,"currency_code":"USD","in_stock":true},{"title":"Front: 14K \/ Rear: 10K","offer_id":67656330215725,"sku":"SF-MB14-06-TR","price":1195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/8295\/1469\/files\/sf-racing-track-coilovers-for-2007-2013-mercedes-benz-s63-amg-rwd-w221-1194291221.jpg?v=1792168924","url":"https:\/\/lowerhq.com\/products\/sf-racing-track-coilovers-for-2007-2013-mercedes-benz-s65-amg-rwd-w221","provider":"LowerHQ","version":"1.0","type":"link"}
