subframe connectors - when?

I think guys get a little too worked up about the frame connector install thing. It's not like they make the chassis a rigid unit. They're a single part of a complex system. Yes, they do add some torsional rigidity, but there's still flex there.

I honestly think you'd have to TRY to put a twist in the chassis with the frame connectors in order to actually do it. Like you'd have to put one wheel in the air with all the others on the ground and then weld in the connectors. I've seen the US Cartool subframes installed while the bare chassis was on a rotisserie on multiple builds, with the chassis upside down or even sideways. Cars always went back together and I've never seen a thread about someone that couldn't get their car aligned right after a subframe connector install.

I'm not saying it can't happen, but I don't think it's as big of an issue as it's made out to be. Best practice is to level the car and make sure everything opens and closes before your start, that's how I did mine. But yeah, I think the margin for error is bigger than most make it out to be.
