It features a monotube design, high-pressure nitrogen charge, and damping curves tuned for grip — so your 3 Series stays flat through transitions, turns in harder, and uses its tires instead of fighting them.\u003c\/p\u003e\u003cp\u003eFull ride-height adjustment and single-knob damping control give you a usable range from street stance to weekend warrior. If the Kontrol Pro feels a touch soft and you're not ready to step up to two-way, the Version RR lives in the sweet spot — a serious coilover for a BMW 3 Series that sees real driving without turning into a track-only build.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStrictly designed and built for Auto Racing\u003c\/li\u003e\n\u003cli\u003eStiffer spring rates and shock valving combined with 20-30mm shorter shock stroke\u003c\/li\u003e\n\u003cli\u003e36 levels of damping which allow you the ability to perfectly dial in your coilover system\u003c\/li\u003e\n\u003cli\u003eCollars and upper mounts made from 6061 aluminum with T6 for increased hardness\u003c\/li\u003e\n\u003cli\u003eAdjustable spring perch for height adjustment\u003c\/li\u003e\n\u003cli\u003eAdjustable lower mount allowing maximum suspension travel\u003c\/li\u003e\n\u003cli\u003eCamber adjustment on many models\u003c\/li\u003e\n\u003cli\u003eAll metal pillowball for added strength and responsiveness\u003c\/li\u003e\n\u003cli\u003eMonotube high pressure design for better performance and heat dissipation\u003c\/li\u003e\n\u003cli\u003eElectroplated body for added protection from corrosion and rust\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eCBM015-RR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDamping Adjustment\u003c\/td\u003e\n\u003ctd\u003e36-Way\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight Adjustable\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate (Front)\u003c\/td\u003e\n\u003ctd\u003e12.0 kg\/mm (672 lbs\/in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate (Rear)\u003c\/td\u003e\n\u003ctd\u003e10.5 kg\/mm (588 lbs\/in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Type\u003c\/td\u003e\n\u003ctd\u003eLinear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop Mounts - Front\u003c\/td\u003e\n\u003ctd\u003ePillowball Mount with camber adjustment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop Mounts - Rear\u003c\/td\u003e\n\u003ctd\u003ePillowball Mount no camber adjustment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNotes\u003c\/td\u003e\n\u003ctd\u003eTrue Rear Coilover Welding Required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1982 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1983 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1984 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1985 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1986 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1987 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1988 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1989 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1990 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1991 BMW 3 Series\u003c\/li\u003e\n\u003cli\u003e1992 BMW 3 Series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eImportant Fitment Note\u003c\/h3\u003e\u003cp\u003eRWD 318i, 320i, 325e, 325i w\/45mm OE Front Strut\u003c\/p\u003e","brand":"KSport","offers":[{"title":"Default Title","offer_id":40190397251644,"sku":"CBM015-RR","price":1963.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0000\/2183\/products\/ksport-version-rr-coilovers-1982-1992-bmw-3-series-rwd-318i-320i-325e-325i-w-45mm-oem-strut-weld-in-true-rear-coilover-e30-cbm015-rr-1194456938.jpg?v=1768966091","url":"https:\/\/www.springrates.com\/products\/ksport-version-rr-coilovers-1982-1992-bmw-3-series-rwd-318i-320i-325e-325i-w-45mm-oem-strut-weld-in-true-rear-coilover-e30","provider":"SPRINGRATES","version":"1.0","type":"link"}
