Each kit is tuned for the specific vehicle it is manufactured for, seeking a balance that handles daily use without falling short on a track day. It features a 46mm piston in a 53mm housing, a combination that increases oil capacity and ensures the shock absorber takes longer to lose consistency. Damping is adjustable via 30 clicks that adjust compression and rebound simultaneously.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW M3 F80 \/ M4 F82 RWD (14-20), 5-bolt top mount. It uses an integrated rear configuration: at the rear, the spring and shock absorber form a single assembly instead of being separate as in the stock setup, which allows for adjusting the rear ride height directly on the shock. Weighs 24 kg. Manufacturer part number I-133-BR-RH.\u003c\/p\u003e\u003cp\u003eEquipped with pillowball top mounts on both axles. 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 shifting with use. Includes dust boots to protect the seals and a 1-year warranty against manufacturing defects.\u003c\/p\u003e\u003cp\u003eSupplied with a single spring rate, 10\/10 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 mounting points. The integrated assembly introduces loads that the original design distributed differently, and BC Racing makes the validity of the kit conditional upon this work being done. This is a job for a specialized shop and should be factored into your budget.\u003c\/p\u003e\u003cp\u003eThe front pillowball top mounts are a rigid connection, without elastic elements, and in some vehicles, 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":"10\/10 kg\/mm","offer_id":60800966984014,"sku":"0071442","price":1438.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/br-1-principal.jpg?v=1791353194","url":"https:\/\/driftandgrip.com\/en\/products\/bc-racing-br-series-trasero-integrado-bmw-m3-f80-m4-f82-rwd-14-20-torreta-5-tornillos","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
