Sounds like the car could use a little wedge (more drive off of the corner) or take some of the loose roll stear out of the car. Lower the right rear trailing arm on the chassis (front bar) this will allow the right side to move rearward less under roll conditions. The upper bar can be moved upward an equal amount, this too will reduce loose roll stear. You will also be differentially adding left rear bite by reducing right rear bite slightly.

one thing i noticed when i was running 4-z is with the rf softer than the LF, the car will tend to compress the rf more when the LR hikes up and take away some bite on exit. i tried the LF stiffer spring trying to get the car in the corner better. but it tended to kill the exit of the corner. same deal too, car was good on small tracks but not as good on the 1/2 milers that way.just something to think about trying.you rear springs sound close. how much LR bite are you running and what angles are your bars on the LR?

Just a point i will throw in but you can rarely have it all.

What i am trying to say is, if you need more coming out, you usually have to give up something to get it, aka looser in.

Swap the front springs on the big track and see what you think.
