F-body roll bars


V8 Beast

Recommended Posts

So what should I put in my car to keep from being kicked out of every track this year?? I'm going with a Wolfe weld in because of the way they fit. Will a 4 or 5 point be enough to get them off my back if I run mid 10's? If a 4 point is enough I can go chrome moly, if I have to go higher it looks like I'll be running mild steel. I also decided to go with welding in the flat part of the back rather than through the rear speakers above the wheel well... unless someone can give me a good reason not to.

 

Any help is appreciated.

I have the wolfe 5 point with the swing out bar. I have the bolt in. It's a very nice fitting piece thats powder coated. I also have the bars that fit flat not on the wheel wells. I welded mine down in the back, bolted it down in the other 3 points. Remember that if you weld it down you are welding above a plastic gas tank. Not for the faint at heart!

The gas tank was my biggest concern. If I bolt it in the back I would have to drop the tank, so I will definitley have someone weld it. Whats the safest way to weld it without messing up the tank.. or blowing something up :eek: ?

 

BYW, bolting the rest of it and welding the back is a great idea. Thanks for the info.

It might be hard to get someone to do it for you. In retrospect it was a really stupid thing to do. If I had burned through that sheetmetal and dropped a dingle berry on that tank it would have blown me to hell. I would drop the tank if I was doing it again.

If I'm dropping the tank I can just bolt in the entire thing. Anyone want to trade a 12 bolt for a 9inch while I have the car apart?

Why not just get a bender and make your own? Mine is all done by hand and I had a blast doing it. It's a 6 point and I mig welded it to the floor and Tig welded all of the joints so it looks sexy as well. I didn't drop the tank either, cause I don't burn through. I would just go mild steel also, chrome molly can be more difficult for some people to weld and with a smaller cage like that the differences aren't going to be very dramatic.

I'm going with a Wolfe 6 point that attaches above the wheel well (so I dont have to worry about the gas tank), and swing out bars.

 

2 questions...

Who is going to help me put this thing in??? And how much welding work is needed with the Wolfe??? (I suck at welding big time!!!)

Brian It only takes a couple hours to strip the seats and carpet out. Strip it down then bolt the drivers seat back in and drive to the shop thats going to weld it in. As long as your not taking the dash out its not to bad a job. Only special tools are the big torx for the seat belts

Weld in, and mild steel. I dont think the extra strength of the chromoly will make a big enough difference in this case for me to spend an extra $300 plus for it.

 

Now if someone can prove me wrong I'll get it, but for right now I'm going with the mild steel.

chromoly is lighter. and you'd only save about 20-30 lbs.IMO steel is stronger. moly tubing is thinner and lighter. I wouldnt go moly till you go full 10 point or more. then the weight savings would be worth it.

 

 

 

A 6-point is only legal to 10.00 and under 135mph.
