What is the purpose of a strut bar or tie bar?

A strut bar is also referred to as a strut tower bar, strut tie bar, and tie bar.  Upper strut bars reduce strut tower flex by tying the two strut towers together. This transfers the load from each strut tower during cornering, which “ties” the two towers together. The lower tie bars, or lower strut bars, improve the handling and steering response of the vehicle by reducing movement of the control and trailing arms and stiffening the subframe. These products are most noticeable during hard cornering.
