Full Length Sub Frames???

The Kenny Brown ones have several braces in addition to the typical subframe connector which offers more support. However, the bars are not extremely beefy and I would be scared to balance a 3400lb vehicle on that thin bar.

Find a manufacturer that uses the full length - much better for stiffness. When you have someone weld it in, make sure the car is resting on all four wheels and not on a 2 post lift. Otherwise you will probably weld the car together with a slight twist to it.

My subs were welded on a two post lift, but they are tubular macs, I heard this before, but the research i've done, I found It is alright to weld them in on any lift, as long as you dont have the car on jackstands or something.
When my car was up in the air we checked the doors, and trunk, and everything was lined up so we started welding, for full lengths you probaly want the car on it's wheels for clearance, full lengths are long. And jacking up the car with a subframe shouldnt be a problem, if anything it is better, than jacking one up without subs, you can actually see the car twisting when jacking up on the frame.

Btw, My friend just got some 5ft long subs with the torque box reinforcement, shops are quoting him 175$ for the welding, because it requires more welding, mine were done 40$ later
