Hard Dog M4 SPORT Bar

Shipping was very quick and everything arrived very well packaged. I was quoted $1200 in labor to install from a Miata specialty shop nearby, so I decided to give it a try on my own. As others have said, mfg instructions were very poor if you're like me and has never removed interior components before. I ended up piecing together instructions from a few different places online and completed the install in about 15 hours over 3 days; if you have prior experience with interior components, you're probably looking at less than half that time. I recommend getting the covers as well as it hides all of the jagged lines on the cut plastic and looks really sharp in the end. It's a very sharp looking product and looking forward to finally getting the car onto my local track.

Roll bar itself is much stronger than the stock aluminum box and fragile looking hoops. Installation was a real PITA and the instructions were next to useless. With better instructions the installation would have been much easier. The instructions SHOULD have identified which bolts to remove (with photos) and which parts would not be reinstalled. Included photos were of such poor quality that it was nearly impossible to determine what they were referring to. I would recommend that you take photos of the fasteners as they are removed so you can identify the proper location when reinstalling them.

Bar was packaged well and arrived in great condition. Instructions on Bethania garage's website were helpful. Originally I was going to leave out all the interior plastics but I realized they are important for supporting the rear window glass with the top down. Also the plastics block a lot of NVH so I did substantial trimming and put the plastics back in for the rear wheel wells and center between the seats. The bar is at least an inch taller than OEM and it may be placebo but the car seems to drive different and better with the added rigidity.

The install was relatively painless and I did it myself over the course of three days after work. I employed the kids to help to lower it into the car so I didn't scratch anything, but other than that it was a one-person job. Note if you are using this to become track legal: I am 5' 9" and my helmet touched (just barely) during a broomstick test. Lowering rails will be required if you are 5' 10" or bigger.

I bought the M4 Sport primarily with mounting a race harness to the integrated bar in mind. I was able to retain the main storage area factory plastic through a simple modification: placing a 'slot' above the driver's side storage bay door. The geometry is: 14-1/4' UP from the main lower push-in fastener center for the slot's centerline + OVER 10' and 16' measured from the centerline of the panel (center of main/locked storage latch or center of the aperture of the roof latch). The 1/2' slot was laid out on painter's tape and easily cut.

Great fit, everything works including the behind the seat storage. Some plastic had to be trimmed but unless you are looking for it it is not noticeable. Bose amp did not require much from my installer. Overall very happy with both the Roll Bar and Good win's speedy service
