Strut Bar HONDA S2000 Z.SPEED

A strut bar, strut brace, or strut tower brace (STB) is a mostly aftermarket car suspension accessory usually used to provide extra stiffness between the strut towers.

In general terms, a strut tower in a monocoque chassis is a reinforced portion of the inner wheel well and is not necessarily directly connected to the main chassis rails. For this reason there is inherent flex within the strut towers relative to the chassis rails.

A strut bar is designed to reduce this strut tower flex by tying two parallel strut towers together. This transmits the load of each strut tower during cornering which ties the two towers together and reduces chassis flex.
