Preparing your car
Remove unnecessary loose objects. The drag-strip has a safety requirement of no "Loose ballast"
Loose ballast is not permitted on the racetrack, so be prepared to empty trunks and interiors of all loose items. Spare tires, jacks, etc. must be securely mounted or must be removed. Tools, jack stands, coolers, loose speakers, wheel covers, etc. are considered loose ballast and are not permitted on the track. If you don't need it, or don't want to leave it unattended, leave it at home.
Any loose odds and ends that you bring with you if you have a bag for them other Tesla owners can hold on to them for you while you race. We typically bring a backpack for those odds and ends, water bottles, purses, etc.
