BC racing’s ER series for the 15-18 BMW F30/F31 3-Series RWD w/5-bolt top mounts is an independent adjustable spring compression suspension.

Increased oil capacity and faster heat dissipation are one of the features this series from BC racing is known for. These coil overs come with an adjustment knob that makes it easy to set the Coilover dampening to your specific needs and adjust compression and rebound together.

You can also adjust how low you want the vehicle by adjusting the shock body, as opposed to cheaper kits that make you compress the spring in order to lower the car.
