In the search for something that improves Korey's asphalt setup, I changed the steering to lowest possible ackerman (bellcrank in the forward position, and bellcrank in the longest position). I really liked the improvement. It gave me more steering and steering feel in the slow corners. I'm pretty sure that this setting has both front tires operating at better slip angles for increased steering.
I also moved the upper shock mount out by one hole in the rear. This was an old change, though, so I don't have comments on it.
