Roll Bar

[63 dream'n]

Angularity is your friend. I think you don’t see a lot of stuff in drag racing as other motorsports because drag racing is behind by at least 15 years especially when it comes to safety. Have you ever seen another form of racing where a plastic seat that looks like it came from a laundry mat is ok in a car going 150 mph? I shouldn’t talk because I still have a bench seat at 132 mph. But at least I KNOW it’s unsafe. And let’s not forget flammable upholstery and carpet.

looks like it’s from a laundromat……… …… thanks for the fantastic belly laugh/tears there Dan……. you’re nucking futs……!!!!

Randy I would put two main hoops in and 4 door bars in that wagon.

You can see my 2x4 inner rocker.

I'll probably put in the "Pro street style" door bars for all four door openings as well. Not for racing so I can put things were I think it will help with safety and yet still allow for us to get in and out without to much hassle.

This is my idea for the Shaker

Put the diagonal down bars on the frame at the front upper crossmember. Put the 'D' bars right on the X of the frame. Like this.

You'll be fine with that, other than entry/exit. IMO.

What’s funnier, the comparison or that I spelled laundromat like a tard?

I do plan on a swingout door bar.

Couple of prayers and bubble wrap, that's what I do. Then again, my wagon has only gone over 100mph a couple times. I'll let you use my bubble wrap James.
On a more serious note about B and (in my case) C pillar roll bar placement. My race chassis builder is going to work on putting roll/side impact bars in my wagon in such a manner for us to still get in and out. We are probably going to run tubing along the rocker panel under the floor to tie everything together to the frame. Can I get some photos posted on here showing how people have done that under the floor? How would you build a roll bar for a 4 door/wagon? My #1 goal is to make the car "safer" for my 3 kids (from side impact) who will be strapped into car seats in the back when we take road trips. The 64 wagon I tried to buy in high school was wrapped around a telephone pole the night before I was supposed to take possession and there was no saving it. Passengers in the back would have been dead for sure. Friend of mine races his 1963 wagon and like everyone else, he would have done his roll bar different. I had a chance to look over his car again 2 weeks ago and the C pillar seams to be the greatest mystery at this point. I don't care if the window in back gets roll bar in its view. I'm not going to fill the back of my wagon with a system like his 63 wagon has. His car has no C pillar protection and that is the most important part of my build.

Just be sure any bar that can be contacted by a skull needs to have a lot of padding. I mean a lot! More than a few people have been killed in regular traffic accidents when they suffered major head trauma after their head hit the tubing.

Even that gets to be a PITA eventually. And on the padding, the "real" stuff is pretty hard, not like that pipe insulation crap or the swimming pool things. It needs to be SFI approved.

It is a race car so it needs a roll bar, time slip told me that. This car will only get a roll bar the 61 will get a cage that will cert. I can get in and out of a caged car and dragsters for that mater.
By the rule book it only needs a door bar on the drivers door. I think I will put one on the passenger side also with a swing out.
I believe the swing out door bar is legal to run.
I was curious if there was a better landing point for the rear bars. I am liking the idea of the the cross member that the upper trailing arms mount.

 

[Ishiftem]

One it will really support that flimsy cross member. The bad is you are attaching a critical brace to a flimsy cross member. Run the main down bars to the frame with drop legs to the cross member. Best of both worlds!

 

[La Hot Rods]

That's what I was thinking to the frame at the crossmember point. Need to figure out my reinforcement for the trailing arm mount point.
