The BR Series is BC Racing's best-selling coilover and the logical first step when moving away from stock suspension. 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 body, a combination that increases oil capacity and ensures the shock absorber takes longer to lose consistency. The damping is adjustable via 30 clicks that adjust compression and rebound simultaneously.
Complete kit for all four wheels of the BMW 3 Series E21 (75-81) (51mm weld-on spindle). Weighs 23 kg. Manufacturer part number I-43-BR-RA.
The front features pillowball mounts, with camber adjustment depending on the application, and the rear features rubber mounts or no mounts, depending on the application. The front axle supports camber adjustment. Ride height is adjusted independently of spring preload, and the tapered lower locking collar prevents settings from shifting with use. Includes dust boots to protect the seals and a 1-year warranty against manufacturing defects.
There are 4 spring rate combinations available, including Extra Low configurations. The default setting BC Racing defines for this car is 5/4.5 kg/mm.
Before you buy
The front pillowball mounts are a rigid anchor point without elastic elements, and on some chassis, 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 mounts avoid this effect.
Installation requires welding and must be performed by a specialized workshop.
