The Morrison setup looks cool. I like the Vette uprights. Lots of brake choices and the geometry should be good with those. I also like the modern approach to wheel bearings. Stick all the wear stuff in a disposable package.
My only issue with the Morrison setup is that I don't see a market for it. It is super expensive and I'm not sure what problem it solves. The chassis shop I work with can install a custom built front stub with a double A arm suspension for less money than the Morrison kit. A custom built front stub frame will be stiffer, have more header clearance, and probably weigh less since it isn't a frame bolted to a frame.
I guess it all revolves around people wanting a bolt in kit. But the Morrison kit seems like it has advanced the concept of bolt in past the point of where it makes sense. If you're going to go to all that work why not just cut the existing front stub off and build a new one that does what you want?
