Help with subframes
 

Guys I finally got my subframes, I remember reading something that when the subframes are install the car should not be lifted from the frame but instead the the car weigh should be supported on the tires.

How true is this as I will have them installed this week.

It is definitely true that you should have the frame loaded the same way that it is loaded when the thing is driving around. Otherwise if you have it on jackstands the frame will have a slightly different loading on it and when you weld the subrames on this will become permanent.
