What are the NHRA rules for a rollbar? I'm not clear on the rules or specs for the nhra on rollbars for convertibles, can someone clear it up for me? For example on a 11.50 can you have a bolt in cross bar behind the drivers seat? How about the side bars?

I believe that is good to 9.99, then you need to have a 10 point cage.
You will also need a helmet (snell 2005 or newer), 5 point seat belt (not sure the limit that this is required) and if you want to run with the top down you need to have the wrist straps.

and I believe a fire jacket when you get in the 10's......not exactly sure though
I know that IHRA rules state that you have to have padding on the cage anywhere your helmet can come in contact with the cage. So depending on how hard they tech your car at your local track you may want to consider that as well. I padded mine, looks better IMO...

To the best of my knowledge...
13.49 and quicker 5 point bar - as stated above.
This will get you to 10.000
quicker than that? 10 point.
The rules also say that if you're fast enough for a bar, you must have a 5 point harness as well.
So, yeh, a stock vert could very likely need a bar.
Some tracks will allow for a hardtop - fiberglass or what ever. Like from Smoothline or Carravaggio. and you can run to 11.49 - same as a hardtop car.
So far, I've only been yelled at a couple times... Once for going 13.0 at 88mph on the brakes... lol
Sometimes at test and tune nights they will let you go - depends on the track. but for any type of competition, you will likely need a bar.
