I had the electrician at work bend some schedule 40 galvanized pipe for my rollbar today. Since I have my interior torn out I figured this would be a great opportunity to install it. The reason I have the interior gutted is, I had upholstery made for my fiero seats that are going to be installed. I also just received a new carpet kit the other day. Back to the rollbar. I built the bases and now that I plumb the bar it doesn't look right. If I lean it back it looks better because it kind of follws the lines of the door opening and the window. The first pic is plumb. The second is leaned back a little. The third pic is leaned back and follws the lines of the car. If I were required to have one at the track, does it matter for the inspection if it is plumb or not? Let me know what you think.

I like it leaned back as well. I did a google search in google images and there are quite a few leaned back. Next week I will have the bars that extend into the trunk fabbed.
If you plan on going to a track the enforces NHRA rules you might want to make sure you're using the right material and make sure it's installed per their spec.

The sch 40 may not be comply. But once painted, who knows. Hope you don't have to test it. The third photo looks best. Most of what I have seen and done are leaned back.
I doubt that I will ever go fast enough to require it at the track. But the coolness and safety factor is there. Schedule 40 pipe is the heaviest gauge pipe we use. Not as heavy as 80, but it is very strong and quite heavy. It's by no means conduit. I think the wall thickness is .145. I'd have to double check. I just googled it. Here is the chart. http://www.mcnichols.com/products/handrail/resources/ pipeDimensionTable.html
im sure if its a open day at track they dont care what kind of bar you have. cause ive seen guys take minivans to autocross lol. you might just have to register in a lower class. idk though cause ive never been to one or looked into it.
Material type matters a lot more than thickness. A .125 thick bar made from 8740 Chrome Moly for instance would be far stronger than a .250 thick bar made from mild steel.
