i use a team magic set up station. it comes in a small carry case.
i personally would not do without mine now
The buggy is so much more consistent when put on the station. i could not get my buggy to turrn equally as good left and right until i found the toe was way out. a few of my race mates have put theres on mine and all have been way out to what they thought they were set up like. i have found my buggy much better and easier to drive so have all the people who used it. i now use my set up station before every race meeting.
