Subframe connectors

You guys do some nice work. I'll add a few things that popped in my head when I read these posts.

A good muffler shop guy could easily weld in your connectors once fitted and temporarily bolted or screwed into place, and there are a lot of those types of shops around.

I stated I stich welded my connectors in place, but they are still fully welded along all contact points. As 72bluNblu said, this makes them much stronger.

I also installed the entire chassis stiffening kit from US Cartool in my car. The shock towers are also fully welded to the inner fenders. This requires repainting the engine compartment, but it is very much worth it, as this dramatically reduces cowl shake especially on washboard style road defects.

Be very careful about removing the undercoating. It is actually some very toxic stuff once loose. I had a friend use the heat and scrape method on a hot sweaty day and he ended up with a horrible rash that lasted for several weeks all over his arms and shoulders.
