Strut tower braces:
aka "strut bars, strut braces, usless cool things, etc." Depending on your chassis, these bars are great mods, or useless. 99% of the bars on the open market are not very effective at what they are entended for. They are ment to connect your strut towers and keep them an equal distance apart while cornering. If you think of your chassis as a U shape. Where the legs of the U are the strut towers, and base the chassis. The strut brace will connect the top, making a square shaped figure. Thid DOES keep the strut towers the same distance apart, but it still changes, remember from HS geometry, a square is a very unstable shape. To make the strut bars more effective, you can place a leg between the bar, and the chassis, before, and below the mounting point. This will help eleminate the tendency to turn that cool square into a diamond in a corner. Even better then that is to connect the strut bar to the fire wall of the engine bay. This will keep the legs of the U from moving side to side, aswell and front to rear. THIS WILL CAUSE MORE UNDERSTEER. It's something you are going to have to tune around. The easies way to counteract that front bar is to install a rear bar. The rear suspention is alittle different then the front. You have changed the U to a H, yet another unstable shape. Best way to stiffent this up is to connect the tops of the H with a strut bar, and a cross bar from one top, to the center of the H. This will make the square formed by the strut bar into two triangles, the most stable of shapes. Then adding a subframe connector to the bottom of the H and the same type of cross bar, will do the same thing. All in all, the strut bars should be one of the last mods you make to a suspention kit. They will only enhance other suspention mods, and will not be a stand alone item.
