Sub-frame connectors... Please build them correctly!

So, I can help but notice all of the sub-frame connectors that many people build, and do next to nothing for the rigidity of the car.

I have noticed the common thing to do is to weld some form of tube from the front sub-frame to the rear sub-frame with no attachment to the floor pan itself. This method is next to pointless. Im sure Ill fire up some huge differences in opinion here, but it truly comes down to fact and not ones opinion.

Adding tubing from front to rear will keep your car from stretching.... That's about it... As far I I have ever known, its just not an issue! LOL

So to explain this a little better, there are some basics in building strength into anything, whether it be full tube chassis fabrication or shoring up your twisting little a-body.

By welding in the tube and only attaching it at the ends, you have accomplished exactly the same strength as the rocker panels already produce. They are already there, so why add additional weight?

The correct way to do this is with the laser cut sheet metal sub frame connectors that conform to the floor pans and are meant to be fully welded.

With the new material being welded to the floor pan, you have now tied, the floor to a rail, which in turn is tied to the front and read sub frames.

The correct way to build these to the point they actually provide structured support is shown in the pictures below.
Even the pictures which dont have 100% weld along the connector is better than the "floating" connectors.
Though it transfers much of the torque to the area that is not welded. This creates a high stress area in a pretty concentrated area.

The bottom pictures are the type that do next to nothing for the problematic area in these cars which is the nearly flat plane of the floor pans between the sub frame sections from front to rear.

Im sure this will chap a few hides, but I hate to see this mod over and over and done for nearly no gain.
