The front sway bar on the 944/968 is designed with the attach points on the end of a long bracket. This bracket has the possibility of flexing forward and backward in a hard turn. If this bracket moves it will allow additional body roll in a turn.
KLA Industries has developed a bracket that will triangulate this bracket to the frame to prevent any movement during a hard turn. The brace secures the mount points of the sway bar so it is held as secure as the rear sway bar. This allows the sway bar to work as it was designed to work and allows it to maintain the body roll properly. Priced per pair.
