It maintains the construction of the BR and DS series, with a monotube shock absorber and digressive piston, and adds 30 clicks of compression adjustable from the reservoir plus another 30 for rebound from the top of the shock. This independence is especially useful when entering a corner: compression determines how the front end loads under braking, and rebound determines the rate at which it recovers when releasing the pedal.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW M3 G80 \/ M4 G82 \/ M2 G87 RWD (+21), 6\/6.5 kg\/mm. It comes in an integrated rear configuration: at the back, the spring and shock absorber form a single unit instead of being separate as in the original equipment, which allows for adjusting the rear ride height directly on the shock. It weighs 24 kg. Manufacturer part number I-134-ER.\u003c\/p\u003e\u003cp\u003eEquipped with  at the front and  at the rear. The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the conical bottom collar prevents the setting from shifting with use. Includes dust covers to protect the seals and a 1-year warranty against manufacturing defects.\u003c\/p\u003e\u003cp\u003eSupplied with a single spring rate, 6\/6.5 kg\/mm.\u003c\/p\u003e\u003ch3\u003eBefore purchasing\u003c\/h3\u003e\u003cp\u003eBefore installation, the chassis must be reinforced in the area of the rear mounts. The integrated assembly introduces loads that the original setup distributed differently, and BC Racing conditions the validity of the kit on this work being performed. This is a task for a specialized workshop and should be included in the budget.\u003c\/p\u003e","brand":"BC Racing","offers":[{"title":"Default 6\/6.5 kg\/mm","offer_id":61096543617358,"sku":"0071543","price":2297.79,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/er-1-principal.jpg?v=1791353540","url":"https:\/\/driftandgrip.com\/en\/products\/bc-racing-er-series-trasero-integrado-bmw-m3-g80-m4-g82-m2-g87-rwd-21-6-6-5-kg-mm","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
