I only install Hard Dog Roll bars. You can purchase these from the manufacture at: www.Bethannia-Garage.com You can have them "drop ship" the roll bar right to my garage. You will not be able to transport the roll bar in your Miata.
What is the difference between a Roll Bar & a Style Bar?
A Roll Bar provides real roll over protection and is braced forward or rearward. A Style Bar looks like a roll bar, but is not braced forward or rearward and can actually collapse in a roll over. I do not install style bars.
How long does a roll bar take to install?
It takes about 10 hours of labor. Plan to leave your car for 2-3 days for the installation.
