Is tube steel stronger than retangle steel?

I would imagine that round Tube would twist less than a rectangle.

 

depends on wall thickness.. round tube is strong in all directions, square is VERY strong in directions parallel to the sides, but less so at angles.
twisting motion is also a bit weaker on a square tube, but generally not the issue with SFCs.

 

to answer your question: Buy the Truax ones, not the Warpspeed....

 

I think he wants to make his own..

 

And why, exactly, are you saying that?

 

Greeny, I like your avatar

 

because if he buys the Truax ones, he might actually get them within a year or two of ordering them. With the WS,

for customer service of truax when the SFCs from either company accomplish the same thing with different designs.

 

Did you mean week instead of year?
WS looks more professional IMO. Nonetheless its "hidden" under the car anyway and both can equally get the job done.

 

I'm making my own. Looks like I'm probubly going with round. I think the tuybe I'm getting is 1" 7/8 with atleast .130 wall.

 

How does round tubing with tabs welded on look more professional than square tubing with tabs welded on?

as SFCs go, neither really looks all that "professional" but they do the job.

this looks professional, if looks are what matter most to you:

 

is that the flyin' miata "butterfly" brace?

 

Yep

 

yep, and as pretty as it looks (and it's very lightweight), it does the exact same thing the truax/WS ones do.

BTW, we put one of those on Cutler's miata last summer, what a PITA even though it's bolt-on. Even with a precision piece like that, CNC cut, we still had some fitament problems.....

 

btw, figures that a Miata brace would be named after something so wimpy as a butterfly

 

"Nobody ever suspects the butterfly." LOL
