When it comes to cornering - especially at high speeds with a fairly heavy, powerful vehicle - the laws of physics, particularly inertia, can very much work against you and put a lot of stress on the entire frame. Vehicles with a unibody design have an integrated suspension that is installed inside of two separate strut towers. This set-up was not designed for high-speed, high-performance driving. When cornering at high speeds, the vehicle is prone to "chassis flex." Over time, this effect gets more and more noticeable, until some real structural damage occurs. The best solution is to tie the strut towers together with rigid braces at the top, which is what the Pilot Strut Bar is designed to do. Attached at either end to the strut towers, the Pilot Strut Bar combats chassis flex by transferring the inertial force created by cornering from one strut tower to another. By holding these elements rigidly together, the Pilot Strut Bar prevents the body of the vehicle from flexing, making the entire car a little flatter during high-speed cornering maneuvers. These are easily installed, even on older cars on which the strut towers have collapsed in on each other - simply raise the front end from the center.
