Steel tube instead of an aftermarket strut tower brace?

[blazenem]

what? why? MoI is a mathematical expression for the disperssion of mass around a "fixed" reference point. Unless you are trying to spin the car around that pipe, MoI doesnt come into play. What he is more concerned with is the static strength of his mod.

In which case it depends upon the direction of the load. Strength-to-weight in lateral bending is good with round. But you get much better rigidity/stiffness torsionally with square-tubing of the same diameter at a slight cost in weight. The equations governing thin-wall tubing is as follows:

Maximum Torsional Stress = T/2*t*Ar where:
T= Torque
t = wall thickness
Ar = cross-sectional area enclosed by the centerline of the tube

Ar for a circular section would be pi*r^2
Ar for a square section would be b^2 (b is the length of the side)
Ignore the equations if you want. Im still a little confused by em myself

stop showing off your smartness


lol j/k

I went to Home Depot and surprisingly they had some square steel tubing that looked perfect for this.
So I got some and decided to practice on my Civic lol. Here is a picture, I welded it with a basic Lincoln flux core welder. This thing doesn't bend at all, I'm pretty happy with the result. This will be just as easy to do in a CB7.

Did you put the rear up on jacks before you welded it in? Usually with the aftermarket stuff with the mount being threaded to the pipe, so you can make it taut.

Nice welds btw

no, I didn't raise the rear when I did it. I wasn't really sure how to do it correctly so I just parked on a level surface and welded it in

and thanks
