01
One event roster
Runnings, cars, availability and driving preferences in one place. Fewer spreadsheets called FINAL-v7-really-final.
Built by GRS · for GRS
Our private endurance operations tool. It turns sign-ups into teams, teams into stint plans, and stint plans into fewer people asking who is driving next.

Discord-gated · member data stays private
What it does
01
Runnings, cars, availability and driving preferences in one place. Fewer spreadsheets called FINAL-v7-really-final.
02
The team builder proposes complete entries around pace, preferences and—most importantly—who is actually awake.
03
A full running order with handovers, named backups and local clock times. No 04:00 UTC mathematics required.
04
Team announcements, race reminders and handover pings go where GRS already lives. Every message is previewed first.
05
Garage 61 data adds measured consistency and car experience to the planning—not invented ratings dressed up as science.
06
Pit Wall proposes. An admin decides. The software organises the chaos; it does not become team principal overnight.
Inside the tool
Pit Wall contains member names, availability and race plans. The public preview below is intentionally redacted. The real thing is available to authorised GRS members through Discord.

Endurance is better with teammates
