HPDE Safety Gear Requirements by Run Group

Safety Gear HPDE GridLife Updated March 2026  ·  ApexReady

Unlike autocross, HPDE gear requirements are not flat. They escalate as you advance through run groups — and the jump from HPDE 2 to HPDE 3 is where many drivers get caught underprepared. A suit that's optional in your first season becomes mandatory equipment at most organizations once you hit the intermediate-to-advanced groups.

This guide covers NASA HPDE run group requirements in detail, GridLife Track Nation requirements, the full comparison table, and a practical gear investment path so you're never caught at tech with the wrong equipment.

Regional Variation Warning

NASA operates regional chapters with some latitude to set stricter local requirements than the national minimum. The requirements listed here reflect NASA national rules as of 2026 — always verify with your specific NASA region's supplemental rules before registering. GridLife requirements are more consistent nationally.

NASA HPDE Run Group Requirements

NASA structures HPDE into four run groups plus an Instructor designation. Gear requirements increase with run group level, with the biggest jump occurring between HPDE 2 and HPDE 3.

HPDE 1 — Novice

HPDE 1 is the entry-level run group. A passenger instructor rides with you for every session. Gear requirements are minimal:

Most NASA regions now require SA2020 even at HPDE 1 — do not assume SA2015 will be accepted without checking. If you're buying your first helmet, buy SA2020.

HPDE 2 — Novice/Intermediate

HPDE 2 drivers still run with instructors available but may run solo once cleared. Gear requirements at most regions match HPDE 1:

This is a good time to start building out your gear collection. You don't need a suit yet, but the investment in a suit between HPDE 2 and HPDE 3 registration means you're never scrambling at tech.

HPDE 3 — Intermediate

HPDE 3 is where requirements tighten significantly. You're running solo, speeds are higher, and the organizations treat you as a more serious track driver.

HPDE 3 Suit Reality Check

In practice, showing up to HPDE 3 without a suit means you may be turned away from running, depending on your region. Even where it's technically "strongly recommended" rather than "required," instructors and event organizers can and do enforce it. Don't risk your registration fee — get the suit.

HPDE 4 — Advanced

HPDE 4 is the highest non-competition run group. Drivers are fully self-sufficient and often preparing for Competition licensing. Requirements are the most comprehensive in the HPDE structure:

Instructor

NASA instructors are held to HPDE 4 gear standards — full suit, SA2020, and HANS where the student's run group requires it. If you're instructing in a student's car, you must meet the student's run group requirements. If instructing in your own car with an HPDE 4 student, meet HPDE 4 requirements.

GridLife Track Nation Requirements

GridLife's Track Nation program uses a different run group numbering system but escalates similarly to NASA. GridLife is generally stricter than NASA at the entry level — SA2020 is required from day one with no SA2015 exceptions.

Track Nation 1 & 2

Track Nation 3 and Above

GridLife Time Attack

GridLife Time Attack events are timed competition laps and carry the most stringent requirements in the GridLife ecosystem:

Progressive Gear Investment Path

If you're starting from zero and working toward HPDE 4 or GridLife Time Attack, here's how to stage your gear purchases without buying it all at once.

Step 1: Helmet (Buy First, Buy Right)

Buy an SA2020 helmet before anything else. It's required everywhere and is the single non-negotiable piece of gear. Don't cheap out — but you don't need to spend $1,000 either. The Zamp RZ-42Y at ~$200 is a legitimate SA2020 helmet that passes tech everywhere. See our full helmet guide for options at each price point.

Step 2: Driving Suit (Before HPDE 3)

Once you've completed HPDE 1-2 and have a few events under your belt, buy a driving suit. A single-layer SFI 3.2A/1 suit in the $200–$280 range (OMP First S, Impact Alpha) is sufficient for HPDE 3, HPDE 4, and most GridLife events. You don't need a multi-layer suit until you're doing wheel-to-wheel racing. See our driving suits guide.

Step 3: HANS Device (Before HPDE 4 / TN3)

HANS devices run $450–$600 for reputable units. Buy one when you're approaching HPDE 4 or GridLife Track Nation 3. Note that HANS requires a 4-point or 6-point harness to function properly — it's not effective with a factory seatbelt. See our HANS device guide for full details on sizing and compatibility.

Step 4: Gloves and Shoes (Add When Budget Allows)

Driving gloves and shoes are quality-of-life improvements at HPDE 1-2, but they're required at advanced run groups. Entry-level driving gloves start at ~$50 (karting gloves work for HPDE 1-3) and driving shoes start at ~$120 for a good SFI-rated pair. See our gloves and shoes guide.

Gear Item When to Buy Budget Option Est. Cost
SA2020 Helmet Before Event 1 Zamp RZ-42Y ~$200
Driving Suit (SFI 3.2A/1) Before HPDE 3 OMP First S ~$240
HANS Device Before HPDE 4 / TN3 Schroth HANS ~$480
Driving Gloves Anytime / before HPDE 4 Alpinestars Tech 1-K ~$50
Driving Shoes Anytime / before HPDE 4 Sparco Slalom+ SP ~$140

What Does a Full Kit Cost?

A complete kit sufficient for HPDE 4 and GridLife Track Nation 3 — helmet, suit, HANS, gloves, and shoes — will run approximately $1,100–$1,400 for budget options to $2,500+ for mid-range across the board. You can build this progressively over several seasons as your run group advances, which is exactly what most drivers do.

The key insight: don't buy a cheap SA2015 helmet to save $50 now. The helmet is the purchase you'll make first and that has to be right from day one. Everything else can wait until the run group requires it.
