Brian,
Most of the guys around here are taking some of the steering out to get the rear to follow. The Losi guys have a loamy track that has tons of bite. We run on hard dusty clay.
Minimize the chassis dive when you are on the brakes.
Change the front springs to green.
If you want more rear bite you can change the rear springs to silver.
Use a soft sway bar in the rear.
I'm running 3-5-3 for my diffs.
Hope this helps,
TEX
