wow what a poop storm this started. i modeled mine after the ones on big block darts website. 2x3 box steel .125" thick layed flat. slotted rear foot well. sure they dont attach to the floorpan except in the back footwell, but based on what most folks do it seemed like the way to go. $35 in materials also cant be beat either.

Lol, and I did the same. While I tend to agree with the OP, I cannot dismiss the fact that the way I did mine made one heck of a difference.

I noticed it immediately when I pulled my car out of the garage and onto the street. My driveway is sloped down and when I pulled off the slope onto the flat surface of the street, my response was, wow. Took it for a blast and man what a difference in the way it rides and handles.

I can also jack my car up now and it had zero affect on the doors too.

So, IMO, doing them that way is far better than not doing anything.

NOW, if you have a serious race built car, I would lean toward connecting them through the floor or welding to the floor for torsional stability.
