I use the Integy setup station and it works fairlly well. I've heard people say that it has alot of slop compared to the Hudy, but I wasn't going to shell out 3X the $ for the Hudy. Having a setup station takes all of the guess work out making adjustments to your car and I believe, is well worth the money. As others have said, you can adjust front and rear camber and toe as well as, steering left and right EPA. Setup wheels only allow you to adjust the camber. Adjusting ride height should be done with the tires you will be using on the track. Adjusting droop doesn't require a setup station or setup wheels, but rather, a droop gauge and blocks.
