In the late '90s I raced Wing cars, eventually working my way up to Group 7. Classes at the USRA Nats were Group 7 Pro, Semi-Pro, Geezer, 27, International 15, and Boxstock.


I was out of the hobby for about 20 years, now the classes run at The Nats are very different. What was the timing (and reasoning if possible) for the changes to the current classes? Did Group 7 price and/or technology itself out of existence?

Group 7 is still there, Opens, just as expensive as ever, if not more so as.


No Pro or Am any more, 27 has become 27 Lite with added rule restrictions. Boxstock has changed its rules and Group F has been added as a lower cost beginner class.

Okay, back in the 70s the Nats was Group 7 only - Pro, Semi Pro, Amateur and Novice.  I am looking for time frames, and opinions as to why, the changes occurred.  I agree that Opens just became too expensive, I am looking for a history lesson of when and how the changes occurred.  Maybe Mike Swiss can chime in I think he was around for just about all of this.

Can't help you out.

The last Nat's I attended was 2006, when I hosted.

Slight correction, I certainly attended the 2020 "Covid" Nats, because I also hosted it.

But by that the time, all the classes already had been "reset".

If you want to know anything about Retro, I can tell you all about that. Lol
