Each phase is adjusted independently: 20 clicks of low-speed compression, 12 of high-speed, and 30 of rebound. Ride height is also adjusted independently of piston travel and spring preload. Inside, a digressive piston and a dual-piston system operate, with one housed in the shock absorber and the other in the reservoir.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW M3 F80 \/ M4 F82 RWD (14-20), 5-bolt top mount, 14\/16 kg\/mm. It comes in an integrated rear configuration: at the rear, the spring and shock absorber form a single assembly instead of being separate as in the stock equipment, which allows the rear ride height to be adjusted directly on the shock absorber. Weighs 24 kg. Manufacturer part number I-133-ZR.\u003c\/p\u003e\u003cp\u003eFront mounts  and rear . The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the tapered 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, 14\/16 kg\/mm.\u003c\/p\u003e\u003ch3\u003eBefore you buy\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 makes the validity of the kit conditional upon this work being done. This is a job for a specialized workshop and should be included in the estimate.\u003c\/p\u003e\u003cp\u003eThe shock absorber is a cartridge housed inside a threaded body, and between both parts there is grease that prevents metal-to-metal contact. It must be cleaned and reapplied periodically to avoid noise; this is simple maintenance that does not require opening or re-pressurizing the shock absorber. For this reason, BC Racing gears this series towards the track and recommends BR, DS, ER, or ZX for a daily-driven car.\u003c\/p\u003e","brand":"BC Racing","offers":[{"title":"14\/16 kg\/mm","offer_id":61096542437710,"sku":"0029652","price":2866.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/zr-1-principal.jpg?v=1791353702","url":"https:\/\/driftandgrip.com\/en\/products\/bc-racing-zr-series-trasero-integrado-bmw-m3-f80-m4-f82-rwd-14-20-torreta-5-tornillos-14-16-kg-mm","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
