Not Ranked
I'm using a 1 3/4" roll bar to meet SCCA requirements so I can track my car. The center to center (diameter) of the radius is 12". It may not make any difference, since racing would require a full roll cage but it couldn't hurt. It should at least suffice for occasional track days and HPDE days.
The originals had 1 1/2" roll bars with 12" center to center uprights.
Personally, I've always thought the 1 1/2" roll bars looked too small for the proper scale and the 2" roll bars (FFR, others) look too large for proper scale. I think the 1 3/4" looks just right. But that is just my opinion and it's worth about what you paid for it.
One thing I found out is that it is almost impossible to find someone to bend my roll bars 6" radius for 1 3/4" pipe size at .134 wall size. I did finally find an outfit in Texas that did a great job for a very reasonable price.
