What to Bring to a Track Day

The ND MX-5 needs almost nothing exotic to run a beginner HPDE, but the difference between a good day and a wasted entry fee is what’s in your trunk. The ND has roughly the cargo space of a backpack, so you’ll be loading a passenger seat, a cooler, and possibly a tow vehicle. Pack deliberately.

This is the bring-and-check list. The night-before car prep (fluid flush, pads, alignment, cooling) lives on track day prep; the items below assume the car is already sorted and focus on what comes with you to the paddock.

The non-negotiables

Without these you don’t grid:

Helmet meeting your organizer’s standard. SCCA, NASA, and most regional clubs require a Snell SA rating (the SA test includes a rollbar multi-impact and flammability spec that the motorcycle “M” rating doesn’t). As of 2026, SA2025, SA2020, and usually SA2015 are accepted, but confirm with your specific event — clubs phase out the oldest sticker on their own schedule. Buy SA, not M, and buy current.
Long-sleeve cotton/natural-fiber shirt and full-length pants. Polyester melts; most orgs require natural fibers in the car. Closed-toe shoes, ideally thin-soled so you can feel the pedals.
Tech inspection form, filled out, plus your event registration and, if required, a recent self-tech or shop-tech signature. Print it the night before.
Driver’s license and any required novice/log-book paperwork.

Tools and the things you’ll actually use

The ND is reliable enough that most paddock tool use is checking, not fixing:

Torque wrench and the 19mm socket for the lug nuts. ND lug nuts torque to roughly 80 lb-ft (Mazda spec ~108 N·m); re-torque after any wheel-off work and again after your first session, because wheels seat. Crisscross pattern.
Tire pressure gauge — a good dial or digital gauge, not the pencil type. Tire pressure is the one setting you’ll adjust between every session, so accuracy matters more here than anywhere else.
A way to let air out — most quality gauges have a bleeder, or carry a separate bleeder tool. You will be dropping pressure, not adding it, after the first hot session.
12V or cordless inflator for the mornings you start too low or have to reset to a cold baseline.
Floor jack and a jack stand (or the factory scissor jack at minimum) so you can pull a wheel and check brakes.
Basic hand tools: 1/2” drive ratchet and metric sockets, a couple of screwdrivers, pliers, a flashlight. The ND’s fasteners are all metric.
Painter’s tape and a marker for numbers/run-group markings if the org doesn’t supply magnetic numbers, plus tape for headlights if you’re on an abrasive surface.
Zip ties and duct tape. The universal track-day repair for a hanging splitter, a loose undertray clip, or a flapping number.

Fluids and consumables

The two ND failure modes on track are boiled brake fluid and heat soak, so carry the means to top off and inspect, not just to drive home:

A bottle of your high-temp brake fluid (Motul RBF 600/660 or ATE Type 200 are the common ND choices) and a basic bleeder, in case the pedal goes long and you bleed at lunch. Detail on brake fluid.
A quart of the correct engine oil. The Skyactiv-G spec is 0W-20; some owners run 5W-30 for hot-weather margin. Either way, carry a top-off quart and check the dipstick when the car cools. See engine oil.
Coolant (Mazda FL22 long-life or equivalent) for a top-off, and a rag to check for weeping. ND2 cars run hotter; summer events are where overheating on track shows up.
Brake cleaner and shop towels for inspecting pads and wiping brake dust off wheels to spot cracks.

Spares worth carrying

Spare brake pads if you’re near the wear limit, plus the tools to swap them. Stock pads can glaze in a single day; a track pad and the ability to change it saves an afternoon.
A spare wheel/tire if you have one, or at least your existing pressures logged so you can rebuild a baseline.
Valve cores and a core tool — cheap, tiny, and they leak at exactly the wrong time.
Spare lug nuts. ND lug nuts are 12×1.5; a galled or lost nut at tech is a needless DNS.

Body comfort and paddock kit

You’re going to be outside for eight hours doing physical work and short, intense drives:

Water — more than you think, plus electrolytes. Heat and adrenaline dehydrate you fast, and dehydration shows up as sloppy late-session driving before you notice it as thirst.
Food and a cooler. Many tracks have nothing on site.
Sunscreen, hat, folding chair, pop-up shade. Paddock asphalt is brutal in summer.
A small first-aid kit, sunglasses, and a phone charger.

The car itself: pre-grid checks

These are the items a tech inspector looks for, and the same things you should verify before every session, not just at morning tech:

No loose items in the cabin. Empty the cupholders, door pockets, glovebox, and trunk. A water bottle under the pedals is a real hazard. The ND’s lack of storage makes this fast.
Battery tie-down secure, no fluid leaks under the car, no play when you grab a wheel at 12-and-6 and 3-and-9 (bearings and ball joints).
Lug nuts torqued and re-checked after the first session.
Brake pad thickness and rotor condition — replace pads under ~3mm, look for cracks.
Cold tire pressures set and recorded so you can chase a hot target (most ND owners on 200-treadwear tires land around 34–36 psi hot). See track tire pressures.
Roof: soft-top down or RF roof closed per your org’s rule for your run group.

The roll bar question — settle it before you register

A stock ND has no meaningful rollover protection, and this decides which run groups you can even enter. Intro HPDE sessions at many clubs allow a stock convertible with the top down; once you move up, most organizers require a roll bar that passes the broomstick test — the top of the bar must clear the top of your helmet (typically by ~2 inches measured horizontally) when you’re seated normally and belted.

For the ND soft-top the practical choices are the Hard Dog bar (around $850, NASA HPDE and SCCA compliant only with the double-diagonal option) and the Blackbird Fabworx bar (closer to $1,400); the RF needs an RF-specific bar. Don’t assume your group’s rule — check it against roll bar options before you pay an entry fee, because a non-compliant car is a DNS at tech.

Logging your day

Bringing a way to record laps turns “that felt fast” into a speed trace you can actually learn from. A phone running a lap-timing app plus an OBD adapter covers most first-timers; a dedicated data logger is the step up. A rigid phone mount and a charger belong in the bring list above. Full breakdown on track day data logging.
