Double-header race weekends now have two 60-minute practice sessions on a Friday instead of a single 90-minute session. The rounds held at Autopolis and Sugo retain the format previously employed for single-race events, with 90 minutes of practice prior to qualifying on Saturday. Races held on Saturday are now run over a reduced distance of 165km, while races held on Sunday, including those held during the single-race weekends at Autopolis and SUGO, are run over 185km. These longer races no longer have a pre-determined pit window, while the shorter races retained the existing pit window.{{Cite news |last=Klein |first=Jamie |date=10 February 2025 |title=Race format, tyres and more: News from Super Formula's season launch event |url=https://japanracinginsider.substack.com/p/race-format-tyres-and-more-news-from |access-date=10 February 2025 |work=Japan Racing Insider}}

A restriction on the teams' activity on race weekends was employed in order to prevent fatigue among staff members. Teams are now required to stop all work carried out in the paddock four hours after the end of the final session, although there are exemptions in cases of cars becoming seriously damaged in incidents.
