The GMP Performance bar has been designed to provide additional safety for Porsche GT4 track day enthusiasts. The GMP bar consists of the main hoop that has 9 bends to contour perfectly with the factory headliner giving optimal amounts of room for vision out of the back glass. The cross bar is positioned behind the seats and bends around the upper center console to avoid cutting the factory carpet and provides an excellent mounting point for your camera. The rear downbars connect to the strut tops improving rigidity with the final bar traversing between the shock towers staying out of the rearward vision in the mirror.
