The RF is a sexy little car, but its retractable top isn't structural. Because of this, many track organizations won't let them on track without some sort of supplemental protection. We're happy to announce that this is now available exclusively from Flyin' Miata! This bar meets NASA HPDE and SCCA Solo and Time Trials requirements when equipped with double diagonals.

We worked with our friends at Hard Dog to give you as much overhead protection as possible. We started with the soft top bar and changed the dimensions to fit inside the tighter confines of the RF roof. The end result has no effect on rear vision, seat travel or headroom.

Now, let's get this out of the way: with this bar installed, you can no longer drop the top. Your retractable fastback is now a non-retractable fastback - or maybe it's a coupe with an odd hatch. If you're a fan of the Miata as a coupe as some of our staff are, this isn't a problem. But you need to know.


Mazda built nice solid mounting points into the car for the factory aluminum hoops. This bar uses them to tie into the chassis, then adds two rear legs for extra strength. The bar is made of 1.75" DOM tubing with a 0.120" wall, almost overkill for such a light car. The new rear legs come with 3/16" backing plates that require six holes to be drilled in the chassis.

Includes a harness bar and retains full function of the stock seatbelts. The double diagonals are spread at the top to provide maximum visibility out the back and stay well clear of the storage compartment behind the passenger seat.

Will be drop-shipped from the manufacturer. Depending on inventory levels, it may take a couple of weeks to ship. Since they're drop-shipped, the tracking number process isn't automated and could be delayed. Available to ship to the US (lower 48) only.



Free shipping inside the lower 48. If you would like one shipped outside this area, please contact Hard Dog directly. These parts will be drop-shipped from the manufacturer. They are usually kept in stock. If not, depending on where the bars are in the production process, it could take approximately 2-6 weeks for delivery. Since they're drop-shipped, the tracking number process isn't automated and could be delayed.

As of writing this review. This is the only solution available if you need a real rollbar for your RF. That should be enough for you to get this thing.

Installation wasn't fun, but doable with the provided instructions and limitted experience. I ended up eliminating the plastic behind the seats which will make your life easier.

I've had it for the better part of a year and secure my harness without issue.

Helps make the RF a legit track car

This bar is really nice. It fits really well and ties in to all of the same structural components of the car as the stock one does plus it has the rear diagonals to make it a 4 point design. All of the holes lined up and the supplied hardware is high quality. The installation is rather involved but not overly complex. I'm very happy with the result and it's nice to have a legit roll bar that will pass SCCA tech. this roll bar will open up a lot more tracking opportunities and also allows me to run a harness and racing seat. The extra level of safety is also great for peace of mind. The instructions were fairly good although there are a few gaps. Trimming the rear plastic pieces to fit around the bar wasn't fun and I hacked up the first one pretty bad. Of course, the second one is perfect since I had something to go off of. Even a rough template would have been nice but I can always buy a new one and try again. Even though the roof is now (mostly) fixed, I don't mind because I never really opened mine anyway. If you save all the old pieces, this installation is reversible should you ever want to sell the car or have your functioning roof back.

Recommended if you like your head.

I am very happy with this roll bar, as before there was nothing for the RF, and now we have a legitimate Hard Dog product. Rear vision is fine and the seats recline the same. The folks at FM were great to work with getting this to be a reality and I am very pleased with the result. The unused window stow space is big enough for some convenient storage.

Recommended for tracked RFs

Very happy with this purchase. I needed to do some modification to a tab on the harness bar so my harnesses would wrap without interference on the bar. Not a big deal but this could be easily corrected in the design. Would have been 5 stars without that issue. While the installation isn't for the faint of heart, it isn't super hard either. Fits well. I didn't put the large plastic piece in behind the seats which meant less cutting of plastic bits. #becauseracecar
