I have an event coming up too! I'll be going to Speed Ventures this upcoming weekend, should be a lot of fun!
I'm bringing quite a bit with me:
-Toolbox with lots of basic tools, duct tape, zip ties, lugnuts, etc
-Towhook (just for fashion...)
-Fluids
-Extra set of wheels and tires (the tires still have about 3/32 on them, so I want to deal the finishing blow before I sell the wheels
)
-Gloves (I just have nomex flight gloves, like what the military uses)
-Jack and stands
-5 Gallon Jerry Can with a donkey dick, so I can bring some extra gas and not pay whatever outrageous price they'll try to sell gas for at the track.
-Wheel chock
And there are some other miscellaneous things I'll be bringing like food and water. And like everyone said, I'm stripping out my back seats etc before going so I'll have that much more room for what I'm bringing and that much less to take out once I arrive at the track.
