I have found tire pressures about 20 work well. The tires balloon with too much pressure as they are so wide. The other thing is the toe in and wheelbase are even from side to side on the car. In other words make the wheels square to the frame. The biggest difference I found for the hunting and darting is to give it plenty of caster in the 4-5 range. It makes the steering a little heavy at low and parking speeds but I like the results on the cars stability.
