    Additional Info:
    The Hard Dog Hard Core series of roll bars biggest difference from the Sport series is most obvious the thicker appearance, since it is made out of 1.75” mild steel tubing. The rear braces of the M1 series are straight and a single diagonal in the main hoop is standard, while double diagonals and even an X-brace are optional. Other options also include high-density foam padding and leather or vinyl covers. The Hard Core series are only available in black powder coated mild steel. This bar is perfect for someone looking for ultimate protection for track events, especially where a roll bar is required for cars with just convertible tops and no rollover protection. The Hardtop version is placed further to the rear, which translates into allowing full seat travel and tilt as well as more head-to-bar clearance.
