RELAY starts at Pit Crew, and it is identical at every tier above it. Pit Crew runs exactly the board Team Principal runs. Paying more never buys you a better RELAY.

Everyone sharing a car needs their own membership. RELAY is per driver, not per team, so each person in the car needs at least Pit Crew for their data to reach the board.

There is nothing to buy or install separately. RELAY ships inside the DNR SimHub plugin, so if you have the plugin and the membership, you have RELAY.

A few facts about how it behaves that people ask about:

• It sends roughly one update a second.
• No history is kept. It is a live picture, not a recording.
• Data is encrypted before it leaves your PC.
• Sharing is off by default. You switch it on, and you can pause it any day.

If you see "Your RELAY membership has lapsed" on the RELAY or My Team page, the membership behind it has expired and sharing stops until it is renewed.
