Dumb roll bar questions.... Can a bolt in rollbar be done with no welding at all? Do you think someone handy who has never done one would be able to install it? Does a rollbar have to be NHRA Certified or is that just a cage? I guess Wolf is the brand to get right? Who makes the best bang for the buck harness?
Thanks
Thanks

I believe that you only need NHRA certs once getting into the 9's and so on. I love the wolfe roll bar, great fit and finish. RCI in jegs has some cheap good harnesses.

Lynda,
Have you been having any problems with tech at HRP?

I guess the rules changed from 2002 to 2003, 2002 rule book pages 208 & 209 say "All vehicles with OEM frame (i assume that is our cars) must have roll bar welded OR bolted to frame; installation of frame connectors on unibody cars does not constitute a frame, therefore it is not necessary to have the roll bar attached to the frame. Unibody cars with stock floor and firewall may attach roll bar with 6"x6"x.125" steel plates on top and bottom of floor bolted together with at least four 3/8" bolts and nuts, OR weld main hoop to the rocker sill area with .125" reinforcing plates, with plates welded completely."
I will check on NHRA.com to see if I can find anything different though.
When will the new 2004 rule books be available to purchase?

No problems at HRP, that is where I do 99% of my racing year round, and I also passed tech at the Thunder Shootout too, all they said I needed to change is where I had my roll bar padding.

the rules havent changed ,if your talking about to the floor mounts yes rollbar can be bolted to the floor if unibody car with plates top and bottom ,if its a chassis car it can also be bolted but to the chassis not the floor pans[again same pages you quoted ] ,but it sounded like you were talking about a bolt together roll bar ,that is not legal,all legal bars are welded together,. and yes if the tech guy is doing there job and its a new car they should lift rugs ,you would be surprized how many frame cars have there rollbars done incorrectly ,and are bolted to floorpans not frames [ a frame car is a malibu,chevlle,corvette,] not a unibody car i.e. camaro,duster ,mustang for examples thnx bob

6-Point Bolt-in can be made NHRA legal with two welds. The rear bars must be welded to the main hoop.
Swing out bars by Wolfe NHRA Legal?
