I haven't tried it preferring to use zero, which I expect toes in slightly on braking for nice tracking, but seems to turn in quick enough. I don't see what weight cars we are talking about other than Doug's which I expect is light. Don't lighter cars turn in better naturally? I guess if we are talking fully loaded Carreras, they probably could use the help at auotx and technical tracks. However, a 1/4 inch seems like a lot to me. I wouldn't want that at 120> mph.
You don't need no stinkin' quick turn in at Big Willow.
