• These guidelines are to help you verify that your Miata is in good mechanical condition and capable of safe operation at high speeds.
  • The following list is a more detailed version of what is on the Tech Inspection Form. It does NOT cover all components within your vehicle.
  • It’s ultimately your responsibility to determine that your Miata is capable of and prepared for safe use on a track.



1990-05 cars in all run groups must have multi-point roll bars with fore-aft bracing such as the popular Hard Dog or Boss Frog bars. The bar must also be tall enough so that the driver’s helmet is below a line drawn between the windshield frame and the top of the bar. Please contact us ahead of time to confirm if you’re not sure about the eligibility of your bar. Full cages are also welcome and encouraged.

2006-15 cars in groups A, B, C and D must meet the same multi-point roll bar requirement as above. The only bars on the market that are acceptable are the Blackbird Fabworx bars, AWR bars with removable rear braces (the “Quick Change”) or Petty bars, the Hard Dog Sport with a Petty bar or the removable dual height Hard Dog Transformer bar. The PRHT version of the Hard Dog Sport bar is not tall enough to be acceptable.

2016-19 cars in groups A, B, C and D must meet the same multi-point roll bar requirement as above. The Blackbird Fabworx and Hard Dog bars are accepted for the roadster. (Note: due to differences in design, the removable rear braces (“Quick Change”),  and Petty bars mentioned above are not required on ND models). At the time of writing, there is no sufficient roll protection for the RF for these groups.

2006-19 cars in group E may use the factory bars behind the seats for protection. In this case, the power top must be closed for both PRHT and RF models.

If you have questions about your bar’s suitability, please contact us.


Sound limits are 103db.

Doors, hood, trunk lid latches all functional.

Car numbers (IDENTIFYING NUMBER CHOSEN BY THE DRIVER DURING REGISTRATION PROCESS) must be at least 12 inches high, on both sides of the car and in a contrasting color to ease in car identification. We encourage an additional smaller number on the passenger side top of the windshield, or on the hood. The corner workers need the numbers in case there’s a problem, and it’s hard to read little tiny numbers when you’re at speed. (Also remember, if the photographer can’t read your numbers, you won’t get your awesome pictures).
