A '''strut bar''' or '''strut brace''' is a mostly aftermarket car [[suspension]] accessory used in conjunction with [[MacPherson strut]]s on [[Monocoque|monocoque or unibody]] chassis to provide extra strength between the strut towers.<br />
<br />
With a [[MacPherson strut]] [[suspension]] system where the spring and [[shock absorber]] are combined in the one suspension unit, the entire vertical suspension load is transmitted to the top of the vehicle's strut tower, unlike a [[double wishbone]] [[suspension]] where the spring and shock absorber may share the load separately. 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.<br />
<br />
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 via tension and compression of the strut bar which shares the load between both towers and reduces [[chassis]] flex. <br />
<br />
A direct result of this is improved chassis rigidity (similar to that gained from a lower tie bar); hence, the understeer is reduced, tire wear improved and metal fatigue is greatly reduced in the strut tower area. Following the aftermarket's lead, some manufacturers have started fitting strut bars to performance models, including the [[Nissan Skyline|NISSAN Skyline R34]] and the [[Holden Commodore|HOLDEN VY II Commodore]], as standard equipment.<br />
