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.

Front upper/lower, rear upper and lower.

Strut bars or strut braces are simply there to stiffen the chassis and make the car a little more responsive. During quick changes in direction the body of the car will actually flex a little and decrease the responsivness.. Strut braces attempt to minimize this.

Sway bars actually help to keep a car level through a turn by limiting the body roll one way or the other. When you turn the tendancy of the cars body is to lean to the outside. A sway bar prevents this to some extent, keeping the car flat and level... the reason that this is good is that it keeps all 4 tires flat and level on the road and it helps keep the suspension at the optimal geometry througout the corner.

Be carefull when your about to change the original, too thick sway bar on the rear can cause "oversteer".

90% of the strut tower bars are "eye candy" for the most part.

A REAL strut tower bar is either 3 or 4 point. Meaning that they also connect to the firewall of the car.

It functions best when cornering at HIGH speeds. On city driving, it's more of an accessory in your engine bay.

But it didn't stop me to have it in our sedans.

The usefulness of a "strut-bar" (your typical 2-point one) will depend on how old and flexy your chassis is. Some newer cars see little benefit from strut bars. The Mazda3, for example, already has extra chassis bracing between the front towers. There will be a difference in the chassis's rigidity, mind you, but not enough so that you will notice. Sway bars or anti-roll bars will make much more of a difference in how a vehicle behaves, usually.

A strut bar isn't necessary unless you have an older vehicle with the strut towers far away from the firewall (the metal partition under the windshield) and your strut bar braces these two against it. A 2-point bar isn't completely useless, mind you, but if your car doesn't come with a strutbar and you're modifying, you might as well buy or fabricate a 4-point or 3-point one.
