Roll Bar Design

[02stu]

I am bending my own pipe for a roll bar and would like to have something to go off of. Does anyone have the dimensions of the autopower bar or any other? I need lengths, angles whatever you got, thanks.

Why not use your car's measurements?
That would guarantee a fit to suit your desires and car. If you are going to use your car for any sanctioned competition, make sure to read up on the rules so your hard work doesn't go to waste.

Good luck!

pipe? are you for real? a roll bar/cage should only be made out of TUBE, specifically DOM.

what bender are you using? diameter and wall of the tube?

by "roll bar" i assume you mean from the b-pillar back?

Talk to SpecE30 racer Han Ah-Sue... he may have some details. At the least, he has a step-by-step photo album.

I'd measure my rear hoop, but I really don't feel like ripping the seats out, again.

Sorry my bad, I'm not useing pipe. I'm useing 2.00x.120 DOM 316 tube steel, which I know is a little large but I have it just sitting around so I have to do something with it. Thanks for the link sharkd
