BC Racing RM Series Coilover Suspension Kit - F31 (3-Bolt Top Mounts) I-114-RM

RM Series Coilover Suspension Kit - F31 (3-Bolt Top Mounts)

For the enthusiast who uses their F31 Touring as both a daily driver and a weekend track tool, the BC Racing RM Series provides unparalleled driver feedback. The inclusion of front pillowball camber plates as standard allows for aggressive alignment settings that sharpen turn-in and eliminate the "mushy" feel associated with OEM rubber mounts. By moving the oil reservoir away from the hub, the fluid stays cooler during spirited sessions, preventing the "damper fade" that often plagues standard suspension setups after consistent hard use. With the RM Series, the BMW F31 gains a level of poise and responsiveness typically reserved for dedicated M-cars. Key Features: Camber Adjustable Top Mounts: Pillowball front top mounts allow for precise camber adjustment and direct steering feedback. Reduced Damper Fade: Inverted layout keeps oil temperature more stable by increasing distance from hot brake components. Bearing-Mounted Spring Platforms: Minimizes friction between the spring and the perch to eliminate "spring binding" and popping. Patented Concave Locking Ring: Unique design ensures that once height is set, the lower mounts remain locked securely against vibration. Serviceable Design: Fully rebuildable with all replacement parts available directly from BC Racing. Specifications: Vehicle Fitment: 2012–2019 BMW 3-Series (F31) Touring / Wagon (3-Bolt Front Top Mounts). Spring Rates (Default): Front: 6 kg/mm | Rear: 10 kg/mm. Optional Rates: Custom springs (BC or Swift) available from 4kg to 20kg+ to suit specific builds. Construction: TIG-welded heavy-duty steel and anodized aluminum components. Warranty: 2-Year limited manufacturer's warranty.
