Paul, if you really want to read about theory on the outside front, go to the eknclassic forums and search “John vs Bill”. It’s a technical discussion from about 10 years ago. While it’s impossible to “simplify” the discussion, one observation that John Learmouth makes is that the outside front does not have to be significantly loaded to make a kart corner quickly.
That particular discussion is more to do with the conceptual approach to kart setup from 2 slightly differing schools of thought.
But if you search anything by John Learmouth, you’ll see he keeps coming back to the same theory.
