I do all my setting up, comm truing andd tire trueing at home. I bring more than enough mototrs and tires with me to the track so i don't have to worry about bringing the lathes.
I bring some basic set-up equipment like a camber guage, droop guage, height guage...ect.
My needs are the following:
-GFX charger and my 30 amp power supply
-Unger 300 soldering iron
-Integy 30 amp Tray
-Novak Smart Tray
-Plenty of spares
-Allen Wrenches and basic tools: small pliers, screw drivers...etc.
-Most importantt is the "air in a can stuff" to blow off all the rubber and carpet fibers from my car.
