FS Rule A2.2.2 in its 2025 version allows teams to manufacture a new chassis without any changes to the last year’s vehicle. In order to enforce that a new chassis is actually manufactured, we will mark the chassis at the first competition that the vehicle is being used in.
In the case of FSA 2025, the marking on the front hoop will be “A 25” which means that the chassis was first used in an official event on July 20th 2025, making it eligible for use in other events until July 19th 2026.

Teams using a 2024 chassis that has already competed late in the 2024 season will receive the corresponding “Xy 24” marking.

Teams using laminate to encapsulate the front hoop: please remove the laminate in a small area as indicated on the drawing, without grinding away any of the metal of the front hoop.

Registered teams will now receive their invoices via email!

If you have any further questions, if possible, please answer directly to the emails you get from us, this greatly improves and streamlines the organisation of requests on our side.

Due to ongoing economic difficulties and the unexpected loss of sponsorships, we have been faced with rising costs in organizing the competition.

Unfortunately, this leaves us with no choice but to increase the registration fee for 2025 now just a few days before the registration quiz.

We are truly sorry to have to make this decision, please find all the details on the “Rules and Documents” page.

Please note that the “FSA Competition Handbook 2025” was not changed in a way that would be relevant for any questions of the registration quiz, see changelog.

On Friday, January 31st the combined FS Austria and FS France registration quiz takes place! To take part, your team has to be properly registered on this website first! Please make sure you follow all the steps laid out in the FSA and FSF Registration Procedure Document

Do not forget about the wildcard application! Be creative, be wild! Further information is in the registration procedure document and in our FSA Competition Handbook
