The Standard M2 Hard Core


The Hard Core Series of bars were originally designed to meet the requirements for participation in the now defunct SCCA Solo 1 class. Some venues continue to utilize these specifications. Check the rules for the particular event in which you plan to participate as the event organizers have the final word on safety requirements. 

This series of bars are legal for, and actually exceed the requirements, for the current SCCA Time Trials, SCCA Solo and NASA HPDE events.

Stock seats and belts are compatible for the competitor that wants to maintain a dual purpose car for street and track events.

The M2 Hard Core models fit all Miata chassis from 1990 - 2005. Specifically designed for the second generation Mazda glass rear window convertible tops or equivalent size aftermarket glass window installed on a first generation Miata. The M2 Hard Core are also compatible will all flexible plastic rear window tops. See our Application Guide for factory glass window specs.

Single or Double diagonal versions available.  
Glass window compatible Harness Tabs for "V" configured bolt-in harness shoulder straps are standard on the M2 Hard Core.
A Bolt-In Harness Bar is needed for situations requiring individual mounting of wrap-around harness shoulder straps.

The Standard M2 Hard Core is the tallest design possible with a functional top but not necessarily the best choice for tall drivers using stock seats because of the more forward placement of the main hoop. We recommend the Hard Core Hardtop version or Sport models for most drivers over 5' 9" with unmodified stock seats. You can see the differences in main hoop placements in the Schematic Views on our Application guide.

The Standard M2 Hard Core is not designed for use with a hard top. The M2 Hard Core Hardtop is built for use with Mazda hard tops and glass rear window soft tops.
