1990-2005 Miata with hardtop, glass or plastic rear window soft top

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 Hardtop 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 FAQ for details.

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.

Bolt-In Harness Bar is needed for situations requiring individual mounting of wrap-around harness shoulder straps. See FAQ for details.

Hard Dog M2 Hard Core Hardtop

The M2 Hard Core Hardtop is compatible with the Mazda hardtop with stock latches and second generation  factory glass window soft tops or like size aftermarket glass rear window convertible tops.

Preferable for taller drivers using stock seats because of the more rearward placement of the main hoop. See the Schematic View below for main hoop placement.





M1 Hard Core Hardtop Schematic



Features include:

  • Full interior width; farther to the rear than the standard Hard Core allowing better head clearance

  • Complete use of hard top and 1999-2005 factory glass rear window convertible top

  • Durable black powdercoat finish

  • Constructed of highest quality 1.75" diam x .120" wall 1026 alloy drawn over mandrel tubing

  • Laser cut 3/16" mounting and back-up plates

  • Complete hardware kit w/ grade 8 bolts

Use measurements above to measure fightment in relation to driver. The Hard Core Hardtop and Sport are slightly shorter and sit farther back than the Hard Core.  The Ace is slightly shorter still but sits the farthest back. 

What are harness tabs? 

The biggest question we get regarding this roll bar is how is it different than the M1 Hard Core Hardtop. The M2 bar utilizes harness tabs instead of a harness bar.  This allows clearance for the soft top glass rear window.  We offer forged eye-bolts and harness clip-ins to utilize the harness tabs with a multi-point race harness.  At right you can see the harness tab in use.  They are located behind the seats and just below the rear deck.

I called these guys about a week-and-a-half ago to get an idea of how long it would take. Originally, they quoted me 4-5 weeks, and it just showed up today! I’ll post an update on the installation and whatnot later this week, but so far I am blown away by the customer service and timing, alone! Thanks TDR, and I look forward to dealing with you guys in the future!
