Chrome is too heavy. Paint it red.

From a cost standpoint, you could EASILY do this for about 50 bucks, assuming you know how to weld yourself, or figure out a bolt/bracket tie point. The most expensive part is the brace between the new bars. That'll have to be cut. Is in necessary? Maybe not. It'* just an idea. My sketches have them in the other two narrow (obtuse) corners, too.

hmmm that'* really far and alot of metal. Hou hard would it be to make the bar from tower to tower and the bars from the center to the fenders aluminum? Do you have a TIG welder?

dont know if this is the right term...but is that a miter angle where the two new pieces attach to the old one?

if its just the 45, does it line up right?

It'* a COMPOUND miter. Double angle. Out and down. Front fenders slope down, we have to meet them. Not a true 45, but if you wanted to copy it, I could give you the exact angle and length. 2D print with all the dims and angles. Obviously, both new bars are mirrors of each other, but are not interchangable due to the compound angle.

Aluminum would flex far too much, and this is .125 wall steel tubing. It'* not that heavy.

lol, I have a bunch of 1x1x 1/8th square tube, we are going to make a front strut brace but going to the front crosmember of the 94 442 as well as an X brace in the rear of the car on a portion of the cage that holds the rear engine subframe.
all ya need is a welder (plasma cutters make fitting it much faster LOL)
so are ya makin that one yourself?

I've been thinking about it off and on for almost 2 years. Every time I open my magic book of bonneville ideas. I've got sketches and ideas about 20 pages thick.

It'* not alot of work, and I have the tools to do it. I'll need the tubing. All my stock is .060 wall right now (left over from building other crap). Steel is cheap though.

The beauty is that if you have the drawings of the angles and lengths, most steel places only charge you for the cut, which you'd have to pay for anyway. I have a friend with a CNC plasma cutter for the plate brace, or I can machine it myself at work. I also have 3 welders (1 oxy/acet, 2 SMAW).

I can tell you that my OEM bar flexes in hard turns. I think I'll feel the improvement from something like this. It was just an idea, and this topic being posted sparked me to get my old sketches out and model it in 3D.

My ideas are yours.

I definately like the idea, it looks really good. I'd be interested in buying/building one. I know someone who can weld and I know someone who can get the parts and steel really cheap for me. If I could get some more in depth stuff on it, that'd be great.
