Stable Energies, the manufacturer of the guide bars, recommends that you may mount your harnesses directly to the guide bar only for low-speed events. For high-speed events, they recommend that you mount your harnesses to the rear lap belt mounting location and use H-style harnesses looped over the guide bar. The bar is not strong enough to directly withstand the forces of a high-speed crash.
I/O Port recommends that you use a roll bar if doing high-speed events. Racing harnesses will lock your body in an upright position making your head the tallest thing in the car. In a rollover accident, the harnesses do not allow you to move and if the roof collapses, you could be killed.
A harness guide bar will allow you to install harnesses at more or less the proper height but have proven illegal for some Solo II classes.
Some guide bar applications may require bending of the brackets to match your B-pillar angle. If you bend these brackets the guide bar will not be returnable.
