Editorial interest 78/100 Selection signal · not a rating of the site

A motorsport platform that combines driver credentials, event discovery, garage records, track setup history, and cold-to-hot tire-pressure calculations.

Landing page captured for the 2026-09-08 issue.

Field notes

The platform organizes track-day records around a portable driver identity rather than a single event organizer. Its sample passport combines an MPI qualification, car information, brake-fluid age, and helmet validity, while event listings expose circuit length, turn count, driver groups, pricing, and remaining capacity. The homepage also separates the free driver layer from organizer tooling, including TrackDayOS administration, direct Stripe checkout, gate QR scanning, and automatic stint logging.
