Best way I have found to setup my rc's is to: get the camber and toe close, then set my ride height with my Losi ride height guage. I use calipers and make the preload on my shock collars exact. Set ride height with the tires you plan to use the very next time on the track. After my ride height is set, I put a set of wheels on my rc without tires. Then set camber and toe. A wheel without a tire is a much better surface to measure camber. For toe, I have a set of 12 inch calipers. I turn on my RC and let the servo center itself, then measure across the front of the wheels, inside edge to inside edge. Then the back of the wheels, basically setting the calipers on the top plate. After toe is set, I drive my rc down the straight really slow and set the trim.
