We run the hell out of the Tamiya FWD cars, both the FF01 (TA02FF) and the FF02. The standard setups for both are stiff in the front, and soft in the rear. You would also generally run a softer insert in the back. The main trick is figuring out how to drive it. It is a whole other world driving them. Tamiya use to have a seperate class in their series, and we still run that class. We even have endurance races with them, 2.4 hours and such. We also have had point series with weight added for the winners and removal for "loosers". After 15 races these things weight 5 pounds without the battery.
