A strut bar, strut brace, or strut tower brace (STB) is a mostly aftermarket car suspension accessory usually used in conjunction with MacPherson struts on monocoque or unibody chassis to provide extra stiffness between the strut towers.
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.
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. To accomplish this effectively (especially on MacPherson strut suspensions), the bar must be rigid throughout its length, and also attached to the firewall.[citation needed]
On versions of the Saab Sonett, the overflow container for the cooling system doubles as a strut bar.
Many manufacturers have fitted strut braces to performance models as standard or optional equipment, including the Acura CL Type-S, Acura TSX, BMW M3, BMW 3-Series, Ford Mustang Bullitt, Holden VY II Commodore, Honda Crosstour, Hyundai Genesis Coupe, Mazda Protege 5, Mazda RX-8, Mitsubishi Colt Ralliart, Mitsubishi Lancer Evolution, Mitsubishi Outlander, Nissan Skyline, Nissan 350Z, Pontiac GTO, Pontiac Bonneville GXP, Saab 900 NG, Toyota MR2, Toyota Solara, Toyota Camry SE, Volvo S60 and the Subaru Legacy
GM vehicles
Many GM vehicles in the 1990s and later came factory equipped with STBs. For example, the Buick Lesabre, Buick Park Avenue, their Olds and Pontiac bretheren, E-body cars such as the Buick Riviera, Buick Reatta, Oldsmobile Toronado, Cadillac Eldorado and Cadillac Seville, and so on. The W-body '91 to '96 Oldsmobile Cutlass convertibles came with a STB, whereas other W-body coupes and sedans did not.
