I hear that using the long upper arm position for the rear roll center addresses the problem completely, but I have not had the chance to try this yet!
Thanks for your responses!

From most of the test reports I get the impression the car is almost too easy to drive
On considering the stock setup we tried many different things, but when push came to shove we decided it is better to get the car too easy than on the edge.
To give some ideas:
- Stand up the shocks. It combines the effect of stiffer spring and harder damping (the shock moves more to a given arm movement).
- You may want to try 35wt oil in the dampers. This is even more so when you use harder springs.
- As mentioned before, the DRS "up" position (relative to the lower arm) will help on throttle steering.
- As Josh said: lower roll center front and/or higher rear
- On grade softer front tires. Although tire wear is already pretty even it makes it even better.
- You may want to try a 1mm split in diameters of front and rear. This gives a perfect 1:1 ratio. In stock form with even tires you'll have a little more front drive. That makes the car (when using a one way) go into the corner sharper (like having a front brake) and understeer a bit more under power.
