You are right, 4 point roll bar. I found at NHRA, dated 2008, roll bars mandatory for 11.49 or quicker (I am assuming 4 point roll bar). A five point roll bar would be needed for 10.99 or 135MPH. I see swing-out sidebars are permitted. A whole bunch of other requirements would be needed but the bar/cage is the biggest PITA. I need to find someone that has a Vette with a swing-out sidebar to see if I can live with it before deciding.
I don't know what time/speed I would get, but I suspect I would need the 5 point roll cage (I would go with the 6 point). Hopefully I get the bugs out of my setup then I can try the strip to see where I am at.
