Active Autowerke E36 BMW Cold Air Intake (CAIS)
An anti-sway bar is designed to reduce body roll. It keeps your vehicle flatter in the turns by transferring the pressure exerted on the outboard
wheels and applying opposite pressure on the inboard wheels. In this way
weight is more evenly applied to all four wheels, helping the vehicle stay
more level with the road.
