Hard Dog Mazda Miata Ace Bar

The Ace, Hard Dog's response to popular demand for a traditional roll bar designed with more rearward placement for better head clearance that doesn't interfere with the stock seat belts. The flexibility of this design allows us to offer this bar in many configurations to include: one or two diagonals, harness bar and side or top main hoop rear bracing. The diagonals and / or harness bar can be located in the main hoop or between the rearward braces. Or if you prefer, no diagonal or harness bar at all. Fits all Miatas from 1990 - 2005, compatible with Mazda hard tops, plastic rear window soft tops and aftermarket or OEM glass rear window convertible tops.* The Ace integrates with the unibody framework inside the rear wheel wells and seat belt towers creating a structure stronger than the individual component parts using the same mounting system as our Deuce model.

Note: Due to the more rearward placement, between the NA and NB seat belt towers, the Ace is 9" narrower than the Sport and Hard Core models. A safety consideration for taller drivers.

NASA HPDE and SCCA Time Trials / Solo compliant when equipped with diagonal bracing.
