{"product_id":"bc-racing-rm-series-bmw-z4-e85-z4m-rwd-06-08","title":"BC Racing RM Series BMW Z4 E85 Z4M RWD (06-08)","description":"\u003cp\u003eThe RM Series features an inverted monotube shock absorber with the oil and gas reservoir at the top, fixed to the chassis. This layout reduces unsprung weight, allowing the tire to better track the asphalt and stop bouncing on rough surfaces. It also keeps the oil away from brake heat, which during intense use rises through the hub and can soften the damping. The 42 mm piston rod adds resistance to lateral loads and keeps steering geometry stable.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW Z4 E85 Z4M RWD (06-08). Weighs 23 kg. Manufacturer part number I-22-RM-MA.\u003c\/p\u003e\u003cp\u003eThe front features an inverted shock absorber with a camber-adjustable pillowball mount, and the rear uses rubber mounts or no mounts, depending on the application. The front axle supports camber adjustment. Ride height is adjusted independently of spring preload, and the tapered bottom locking collar prevents the setting from shifting with use. Includes dust boots to protect the seals and a 1-year warranty against manufacturing defects.\u003c\/p\u003e\u003cp\u003eThere are 2 spring rate combinations available. The one BC Racing defines as default for this car is 5\/8 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 the two parts to prevent metal-to-metal contact. This must be cleaned and reapplied periodically to avoid noise; it 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 for a daily-driven car.\u003c\/p\u003e\u003cp\u003eThe front pillowball mounts are a rigid anchor with no elastic element, and on some chassis, they transmit slight knocking to 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 mounts avoid this effect.\u003c\/p\u003e","brand":"BC Racing","offers":[{"title":"Default 5\/8 kg\/mm","offer_id":61096690843982,"sku":"0024750","price":1499.19,"currency_code":"EUR","in_stock":true},{"title":"8\/12 kg\/mm","offer_id":61096690876750,"sku":"0024265","price":1499.19,"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-z4-e85-z4m-rwd-06-08","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
