National Auto Sport Association Arizona event at Firebird Raceway in Chandler, AZ. The event offers multiple participation formats to suit drivers at every experience level:

**HPDE 1 – Beginner:** The starting point for drivers new to track events. Includes classroom instruction plus one-on-one in-car coaching. Passing is allowed only on main straights with a point-by from the car ahead.

**HPDE 2 – Novice:** For drivers comfortable running without an in-car instructor. Run group rules are similar to HPDE 1 with limited, controlled passing. No passengers permitted.

**HPDE 3 – Intermediate:** For drivers with solid experience and consistent pace. Passing is allowed in approved zones with some restrictions and point-bys required.

**HPDE 4 – Advanced:** For experienced, predictable drivers. Open passing with courtesy and point-bys expected.

**Time Attack (Sunday only):** Available to drivers in HPDE 3 and above. Three laps — one warm-up and two timed — with only the fastest lap counting. Available with transponder rental ($30) or without ($20) for drivers who have their own. Must be combined with HPDE 3, HPDE 4, Time Trial, or Race Group registration.

**Time Trial:** Competitive timed sessions for fastest lap times across multiple sessions. A valid NASA Time Trial or NASA Competition license is required.

**Race Group:** Wheel-to-wheel competition for licensed competitors. A valid NASA Competition Racing license is required.

All participants must pass a tech inspection before driving. NASA membership is required — annual memberships and event registration are available at members.drivenasa.com.
