why shouldnt you compare the two?
if everything is adjustable except track and wheelbase, there is no reason you cant make any car handle any way you want it to.

plus like you just said.
"scc pulled .97g on an s13 with 235's"

so with say a 255, which is a reasonable size, and can be had in decently sticky compounds, over a g is certainly possible.
and if you think there is anything where pulling one g isnt enough, then youre kidding yourself in my opinion.
