About GB4 Winter Series

The inaugural GB4 Championship Winter Series will take place at the Snetterton 300 circuit on 24/25 October 2026.

The two-day event will feature a total of two qualifying sessions and four races, with each day featuring one qualifying and two races. The full provisional schedule is shown below. Pre-event testing will take place on the Thursday and Friday ahead of the event.

Each event day will run under a separate permit, and teams are limited to four cars per event. However the split permit format means teams can change their driver line-up mid event should they wish, or stick with the same drivers throughout the duration.

Entry and registration fees are combined for a cost of £2,400 + VAT for the full weekend. Entries can be made via the GB4 Teams Area.
