The four things people actually forget
- Driving licence. No licence, no sign-on, no track day. It happens at every event.
- Tyre pressure gauge. The most-used tool of the day. Hot pressures rise 4–6 psi and need bleeding back after every early session.
- Torque wrench + your wheel socket. Heat cycles loosen wheel nuts. Re-torquing at midday is non-negotiable, and borrowing one gets old fast.
- Water — 2 to 3 litres. Dehydration destroys concentration long before you feel thirsty. This is safety equipment, not comfort.
You — gear and clothing
- Helmet in good condition, current standard. Car organizers accept most motorsport and motorcycle helmets; a few rent them — book ahead.
- Long sleeves and trousers in natural fibres for car drivers — cotton doesn't melt; many organizers require covered arms and legs.
- Riders: full leathers, back protector, gauntlet gloves, ankle-covering boots. Scrutineering will look, and textile shortcuts get refused.
- Thin-soled shoes beat chunky boots for pedal feel. Dedicated driving shoes are a luxury, not a requirement.
Tools, spares and fluids
- Basic tool roll in your vehicle's actual sizes, plus pliers and zip ties.
- 1 litre of your engine oil — track days consume oil, and the right spec at the circuit shop is a lottery.
- Small unopened brake fluid bottle, duct tape, painter's tape (numbers, headlight taping).
- Fuel cans if your circuit has no pumps — check its website; plenty don't.
- Trailer users: rated straps ×4 plus spares, and wheel chocks.
Comfort that is actually performance
- Real food and salty snacks — track catering is a queue and a gamble.
- Sunscreen and a cap. A paddock is a car park with zero shade.
- Full rain gear and spare dry clothes when the forecast is anything but certain sun.
- Folding chair, power bank, small first aid kit.
The full list adapts to your situation — bike vs car, trailer vs driving there, rental vs your own, day trip vs overnight, dry vs wet. That's what the planner is for.
