If you have the Avid sets I'd try red front and white rear. That's about as close to Green/Green as you'll get. If it still is hard to drive try the Purple front. Get the car to the point that it is had to get it to turn and then back off until you have enough steering and can lay down the power.

Ryan's suggestion of +.5 or +1 hubs might be a good idea if the track is always loose too.
