at work i was talking to a guy who is a pretty smart car guys, has built some engines and is a GEAR HEAD. I dont doubt him at all.

but here it is.
I mentioned getting subframes for my car and he said to do this.
-buy the bolt on connectors. and install them
-take 4 jackstands and put the whole car in the for like 6 hours, this will enable it to sort of settle down
- go out, loosen all the bolts on the SFCs, retighten them, then weld up the SFC

let the car down. and should be nice and tight

Sounds worth trying. anyone heard of stuff like this?

Welding them in place is the only way to get subframes to do what they are supposed to do.
The bolt holes will elongate over time and won’t hold everything tight like they should. Anytime you put a bolt through a thin metal section like the body points where the subframes would bolt on to, you risk collapsing the metal channel. Once the hole distorts, you loose all structural rigidity.

so your still welding them...it sounds like it is just a trick that may help get them to make good contact...using the bolts to hold them in place for you while you weld...hell i'd do it

What he is trying to do by that methoud is have the subframe conectors loaded up (stressed) before you weld them in. So everthing is nice and taunt, that is a good idea, what is a better idea is actuly use weld in subframe conectors (the one that go through the floor) so you also get the shear streangth of the floor pan in addion to conecting the tow subframes. much better
