With the oil and gas reservoir anchored to the body instead of the hub, unsprung mass is reduced: the wheel responds faster to every irregularity and maintains better contact with the ground. That same position protects the oil from the heat generated by the brakes, so the damping performance remains as consistent on the last lap as it was on the first. It features a 42mm shaft, which is more resistant to lateral stress.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW M3 G80 \/ M4 G82 \/ M2 G87 RWD (+21), 7\/14 kg\/mm. Weighs 23 kg. Manufacturer part number I-103-RM-MA.\u003c\/p\u003e\u003cp\u003eThe front is fitted with an inverted shock absorber with a camber-adjustable pillowball top mount, and the rear uses rubber top mounts or no top mount, depending on the application. The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the tapered bottom locking collar prevents the setting from moving with use. Includes dust boots for seal protection and a 1-year warranty against manufacturing defects.\u003c\/p\u003e\u003cp\u003eSupplied with a single spring rate, 7\/14 kg\/mm.\u003c\/p\u003e\u003ch3\u003eBefore you buy\u003c\/h3\u003e\u003cp\u003eThe shock absorber is a cartridge housed inside a threaded body, and a grease is applied between both parts to prevent metal-to-metal contact. It must be cleaned and reapplied periodically to prevent noise; this is simple maintenance that does not require opening or repressurizing the shock absorber. For this reason, BC Racing targets this series for track use and recommends the BR, DS, ER, or ZX series for a daily-driven car.\u003c\/p\u003e\u003cp\u003eThe front pillowball top mounts are a rigid mounting point with no elastic element, and in some body styles, they may transmit a slight knocking sound into the cabin. This does not indicate a defect, and BC Racing does not cover it under warranty nor accept returns for this reason. Configurations with rubber top mounts avoid this effect.\u003c\/p\u003e","brand":"BC Racing","offers":[{"title":"Default 7\/14 kg\/mm","offer_id":61096543715662,"sku":"0034368","price":1559.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/rm-1-principal.jpg?v=1791353426","url":"https:\/\/driftandgrip.com\/en\/products\/bc-racing-rm-series-bmw-m3-g80-m4-g82-m2-g87-rwd-21-7-14-kg-mm","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
