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.

Single main hoop diagonal brace and integral harness bar standard - a second main hoop diagonal brace may be added for extra strength and better rear vision. Or get the X Brace Diagonals for the ultimate in strength. There's no room for a PROPER straight integral harness bar with the X Brace strength optimized diagonal angles. A Bolt-In Harness Bar is required for harness shoulder strap mounting with the X Brace.

The M1 Hard Core Hardtop models fit all Miata chassis from 1990 - 2005 and are specifically designed for plastic rear window convertible tops. Not compatible with glass rear window soft tops.

Hard Dog M1 Hard Core Hardtop

The M1 Hard Core Hardtop is compatible with the Mazda hardtop with stock latches and all plastic rear window soft 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:

  • Allows full seat travel and tilt

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

  • Complete use of hard top and soft top

  • Durable black powdercoat finish

  • Single main hoop diagonal brace and harness bar standard

  • Second main hoop diagonal brace may be added for extra strength and better rear vision

  • X Brace version for the strongest bar available **

  • 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. 

The biggest question we get regarding this roll bar is how is it different than the M2 Hard Core Hardtop. The M2 bar utilizes harness tabs instead of a harness bar.  This allows clearance for the soft top glass rear window.  If you have a glass window soft top or plan to install one in the future, order the M2 version

The Bolt-In Harness Bar must be used for harness attachment with the X Brace Diagonals.

NOTE: This item has flat rate shipping. All Hard Dog products must be ordered individually for our website to calculate shipping.
