OK, I haven't really read the spce on this one, but I'll make some suggestions.
1) Lower the VCD if there is one to 20%, and reduce the initial torques and accel effect on the front diff.
3) Stiffen the rear springs, and soften the fronts, to allow it to transfer more weight forward more quickly.
4) Soften the front rebound and stiffen the rear rebound to reduce acceleration understeer. Do the same things with bound if it plows under braking.
5) Lower the rear ride height to bias the static weight distribution toward the fron a little more.
Hope this helps and wasn't stuff you already knew. PS, Zero, how are you doing on Rnd 5?
