What do you bring to the track with you for a day of racing?

I was curious as to what kind of equipment people bring to the track for a day or weekend of racing. Obviously you load up your race car and safety gear. What kind of spare parts do you bring? How many and what special tools? How elaborate of repair equipment? Generators, air compressors, welders, what ever? Obviously the answers will vary depending on the level of racing. Looking forward to your answers?

as said..generator..battery chargers.. air compressor..timing light...remote starter...spare fuel pump..spare distributor..all cars have the same one...spare plug wires...spare msd 6al ....floor jack...jack stands..

extra oil...trans fluid.brake fluid..brake cleaner...bicycles...extension cords...ice chest..food and water.

as far as repairs...usually only fix minor stuff like rockers or pushrods...anything else it goes back on the trailer...Most of this stuff is in the lower compartments of the motor home so it is always there no unloading

I do benefit from only being 5 miles to my garage from home track...so If I need anything it is only minutes away....now if we go out of town...I bring the kitchen sink
