"really to race"
even some of the world fastest guys don't use setup stations. The Hudy thingy looks really sweet, but with eye you get it close enough. Nobody cares what degree your tires are lying as long as it works. If it doesn't, do some small changes and try again. If it works then good. Just measure that the turnbuckles are about the same length in both sides. If it makes you somehow faster that you know that both sides are under 0.01mm tolerance and really can tell the difference... the go ahead, get the station. My point being: Setup the car with a station, drive it, do some small adjustment to the other side of the car only and drive again, and tell the difference. (If you pass that test, let your friend do the adjustment without you knowing what he did, drive the car and tell what he did.)
In offroad circumstances the car takes such a beating and the track changes so much that those finetunings you can make with the station dont result in any real advantage.
Like JQ said, setup station just made him slower.
(But for pit-respect that thing is priceless and as said before, looks damn cool. But the real advantage in my opinion is a bit overrated.)
