You want a setup station, tweak station, ride height gauges, droop gauges and weight scale.
A setup station will allow you to set the angles of all 4 tires (camber, toe, track width) A tweak station like the one included in the Hudy All-in-One checks that all 4 corners are in the same plane. There are other tweak stations like the PPD Billet that check chassis tweak.
Ride height, pretty self explanatory, checks distance between the chassis and ground.
Droop gauges check how far the arm falls in relation to your ride height. Droop allows the ability to change how much weight transfer can happen on or off power.
Weight scale, you dont want to be underweight, as thats cheating, and you don't want to be overweight unless it gains an advantage somehow (not usually)
I recommend downloading the Hudy Setup guide here
Other tools that may be useful:
Tire warmers such as the Much More Tire Warmers
Tire Truer if running foam tires.
