Low-speed compression governs how the body settles under braking, cornering, and acceleration; high-speed compression handles kerbs and bumps; and rebound, which is independently adjustable, controls the wheel's return after each compression. There are 20, 12, and 30 clicks respectively, featuring a digressive piston and a double-piston design.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW M3 F80 \/ M4 F82 RWD (14-20), 3-bolt top mount.

This must be cleaned and replenished periodically to avoid noise; it is simple maintenance that does not require opening or re-pressurizing the shock absorber. For this reason, BC Racing targets this series at track use and recommends BR, DS, ER, or ZX for a daily-driven car.\u003c\/p\u003e\u003cp\u003eNot valid for the convertible version.\u003c\/p\u003e","brand":"BC Racing","offers":[{"title":"Default 6\/13 kg\/mm","offer_id":61096543453518,"sku":"0060487","price":2612.39,"currency_code":"EUR","in_stock":true},{"title":"14\/14 kg\/mm","offer_id":60767496765774,"sku":"0090353","price":2612.39,"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-bmw-m3-f80-m4-f82-rwd-14-20-torreta-3-tornillos","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
