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 withstands daily use without falling short on a track day. It features a 46 mm piston in a 53 mm body, a combination that increases oil capacity and allows the shock absorber to maintain consistency for longer. Damping is adjustable via 30 clicks, which adjust compression and rebound simultaneously.
Complete kit for all four wheels of the BMW M4 F83 Convertible RWD (14-20) (5-bolt fitment). Weighs 23 kg. Manufacturer part number I-69-BR-RA.
The front features pillowball mounts with camber adjustment depending on the application, and the rear uses rubber mounts or no mounts, depending on the application. 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 during use. Includes dust covers to protect the seals and a 1-year warranty against manufacturing defects.
Supplied with a single spring rate, 6/14 kg/mm.
Before you buy
Front pillowball mounts are a rigid attachment without an elastic element, 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.
