In a  nutshell, they work, but nowhere near as well as weld in ones.  Over time they tend to distort at the bolt holes becoming even ,less effective. 

I built a set of these weld-ins:

Perfect fit!

Torque boxes are definitely needed for cars that don't have them, but SFCs are still THE best chassis stiffening you can do short of a roll cage, and even a cage would need SFCs to tie into.  There's just no skirting the issue that the car lacks a full length frame rail.  That only gets addressed by installing SFCs.

I had the complete TCP subframe connector installed.  I did the main install myself with just the car raised on cylinder blocks and a mig welder.  I had the exhaust shop finish up the weld when they put in the custom exhaust.

They’re concrete blocks nowadays....not cinders.
That’s old skool man.

This is why you want some really heavy duty welded-in subframe connectors.  No damage to anything.

That would call for an underwear change.

I'm thinking the OED is going to be adding a couple that he created!

Lucky dog could have been a lot worse, oh by the way I like how you have your fuel line, probably going to steal that idea after I get my subframes put in..... And after the move, setting up the house, then the garage then........sound like a winter project.

This was the only damage.  Nothing bent.  Just scratches. Thanks to the heavy duty Tin Man welded subframe connecters and the mufflers being as high as possible to begin with.

I was lucky.

How did this happen Steve? You were very fortunate to just get out of it with a few scratches and it not be a Ferris Bueller incident (remember the classic Ferrari)...
