I had made a post about making my own SFC.

I bought some 1x1x48" material from my local Tractor supply. 2 pcs $20.00
The car is nice and stiff now.

It worked out very well. I used the full length 48" tube. It started Just behind the tranny cross member bracketry and ended right at the end of the rear subframe before it curves up.

I used my little Lincoln flux core mig welder and did the install in my garage.

I know many people say you should not install them on jackstands.
However:
I have spoken with a close friend of the family about this.
Danny has built more race cars than I can account for. I am talkin 1200 hp + street rods and track racers.

He assured me that it would be fine as long as I supported the car on 2 solid frame points.
Since then I have welded in several sets of mustang SFC's on jack stands in my garage and I also did 1 trans-am.

None of the cars have ever sat funny nor have the owners complained.
This time I even measured before and after and the car sat exactly the same. :nice:

With that being said heres some pics.

just curious.... any reason you welded them right out instead of just stitch?


I figgured the more I welded the less chance there would be for it to break the weld or rip away from the subframe.

Its personal preferance. The passinger side is stiched more than solid due to the shape of the subframe and the dents it had from jacks.
 
Ive been a welder fabricater for 20 yrs. It is possible to lay a long weld and not over heat it.

You can weld an inch or 2 and jump to another place. weld there and jump to another place etc etc.

The welder I use is a very small one and dosent make alot of heat compared to higher amperage ones.
I didnt burn through in one place,so it is all good.

Like you said. It coul dbe stiched and hold well.

I just prefer to connect the SFC to as much metal as possible.
 
you just have to space the welds apart some and keep moving around and not stay in the same area.

bloopbloob is right it can be stitch welded also. I just prefer to solid weld as much of it as possible.

When I put floor pans in a 66 mustang and a 70 mach1 for my buddy I welded all the way around. I would stitch about 2 inches and go weld somewhere else etc etc etc.

When it was done it was strong. and it didnt need to be seam sealed.

Some people consider it overkill, I just prefer to do it the way I feel is right.
