It is adjusted with 30 clicks that act on both compression and rebound simultaneously, and the shock body comes in satin chrome. A digressive valve does not dampen at the same rate at all speeds: with the piston rod moving slowly, such as when braking or cornering, it offers high resistance and keeps the body flat; when the movement is fast, such as when hitting a curb, it opens up and allows the wheel to rise without transmitting the entire impact.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW 3 Series E30 Sedan (82-91). It uses an integrated rear configuration: the spring and shock absorber form a single unit instead of being separate as in the factory setup, which allows for adjusting the rear ride height directly on the shock absorber. Weight is 24 kg. Manufacturer reference I-87-DS-DH.\u003c\/p\u003e\u003cp\u003eFront mounts  and rear mounts . The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the conical lower locking collar prevents the setting from shifting 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, 6\/5 kg\/mm.\u003c\/p\u003e\u003ch3\u003eBefore you buy\u003c\/h3\u003e\u003cp\u003eBefore installation, the bodywork 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 job for a specialized workshop and should be included in the estimate.\u003c\/p\u003e","brand":"BC Racing","offers":[{"title":"Default 6\/5 kg\/mm","offer_id":61096548565326,"sku":"0070751","price":1546.38,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/ds-1-principal.jpg?v=1791353478","url":"https:\/\/driftandgrip.com\/en\/products\/bc-racing-ds-series-trasero-integrado-bmw-serie-3-e30-sedan-82-91","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
