Rather than all this nonsense about changing car specs for either class - FA and F1000 - how about something simple that costs no one anything, can be implemented in a heartbeat, and would give the on-the-fence car owners a reason to come back and race?
Have F1000 remain as it's own class, as is, according to the F1000 rules, and just run as a separate class within the FA on-track sessions?
Unless the goal of the BOD is to get the class to collapse and disappear, there is no reason that this cannot be done.
