The BR Series is BC Racing's best-selling coilover and the logical first step when moving away from stock suspension. Each kit is fine-tuned for the vehicle it is manufactured for, seeking a balance that can handle daily use without falling short during a track session. 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 adjustment features 30 clicks that modify compression and rebound simultaneously.
Complete kit for all four wheels of the BMW 3 Series E21 (75-81) (45mm weld-on spindle). Weighs 23 kg. Manufacturer part number I-48-BR-RA.
The front features pillowball mounts, with camber adjustment depending on the application, and the rear features rubber mounts or no mount, depending on the application. The front axle allows for camber adjustment. Ride height is adjusted independently of spring preload, and the lower locking collar prevents the adjustment from shifting with use. Includes dust covers to protect the seals and a 1-year warranty against manufacturing defects.
There are 3 spring rate combinations available, including Extra Low configurations. The one BC Racing defines as standard for this car is 5/4.5 kg/mm.
Before you buy
Front pillowball mounts are a rigid anchor, without elastic elements, and in some bodies, they transmit a slight knocking sound to 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.
