"I have tried this a few times. its mind boggling, but from what I experienced more the axle back farther from the driver helped the kart rotate at corner entry."
"at center off the kart wanted to drive up the track."
Before I reply there are two kinds of adjustments you can make. One is a permanent change and will stay that way through entry, mid corner, exit and the straight. The second kind of adjustment is more mechanically and can change things more at one part or the track then another.
Those two things changing together tells me, first the RR had too much load on it during entry. Moving the axle forward permanently removed load from the RR moving some to the LR, allowing the LR to get more braking action because of the load shift to it while decelerating. The end result was you got you more rotation going in. And because the load was shifted to permanently stay on the LR with less for the RR on acceleration, the RR didn't have enough load to be able to out accelerate the LR and it wanted to drive up the track. Wanted to means you had enough turn up front, were able to over come the direction the rears wanted to go and there was still enough grip in the back that you didn't get loose off. I'd say the other problem it created is it tightened up the kart and you slowed not because you had to slow down to keep it in control, but it just at hp.
or not, but it was fun to think on and thanks for the fun

hummmm... If I was sort of correct, i'll bet your next question is if I need more rotation going in and it's because of not enough load on the LR going in or too much on the RR going in, how do I fix it without effecting exit. ...
heck I don't know. ...
