BMW 6 Series (E64) Tie Bars
The BMW 6 Series (E64) lower tie reduces the non-pivoting movement of the BMW 6 Series (E64) control arms and makes the subframe stiffer. This lessens the distortion of the BMW 6 Series (E64) lower suspension, which is useful during hard cornering. In general it, it improves the handling and control of the vehicle.
