what fronts (tyres) do you run? run stock foams with rib front tyre (losi are best imo), run wide arms and long turnbuckles for more agressiveness. Go for more anti-squat for less sidebite (more rear end steering). try 10g weight under the front pivot plate or servo horn.
25wt fluid, regular shocks, try an orange or silver front spring, green for a more hard packed track.
I go with that sorta setup for a damp and slightly muddy clay track, after a few races the track dry's right up and becomes harder. I switch to a taper front tyre (rather than rib), or a tyre with more finer ribs in it, like a Panther "lynx".
take a look at what others are running, esp the faster guys, but remember, someone elses setup may not suit your driving at all! make small changes, one thing at a time. I would try tyres first. then weight, then fluid, then turnbuckles then arms
try the simplest thing, give the throttle short and quick stabs through the turns, see if you can get the rear to do more steering for you..
