For those wanting to tame down the steering a bit, on my OCRC no swaybars setup, I backed out the steering stop screws about 1.5 turns and re-set my EPA. I used the width of an x-acto to set the spacing between the screw head and the caster block. This is much smoother and still does the tight turns with ease.

Also for tires, a bow-tie SC or other large block front tire will make the truck push if that's what you want.

For those running 540 motors and wanting to lower temps, try getting a larger diameter rotor if the manufacturer makes one. For example, LRP x-12 motors come with a 12.5 mm rotor but the is an option 13 mm rotor.
