Here at Hard Dog we offer an extensive line of Roll Bars for the 2006 - 2015 3rd Generation MX-5. Built from heavy wall tubing these bars are a serious upgrades from the stock NC equipment.
The factory cross brace is reused making it easier to remount OEM accessories and no alterations to the stock seat belts are required.
The M3 Sport utilizes the factory hoop mounting points with additional lower plates bolted through the bulkhead using grade 8 bolts and reinforcement plates. Additional rearward support is provided by 2 rear braces w/ large 3/16" mounting and back-up reinforcement plates anchored with grade 8 bolts and self locking nuts.
Because of the additional height and rearward braces, the M3 Sport is not compatible with the retractable hard top.
The standard main hoop is as tall as the soft top will allow. A slightly shorter version is available for the removable hard top.

Two main hoop diagonal braces and / or harness bar and / or removable forward bracing may be added.
