It's OK to quote me... but here is the rest of that story.... while the switch from "wedge" bodies to stock cars killed the Group 10 class over time... at the same time we were running "wedge" bodies in Group 10... the next largest class and almost the same in numbers of entries at the scale Nats for a few years was the 4.5" Stock Car class.To quote Ron Hershman from another blog in reference to USRA racing:
"The Group 10 class was the largest when Wedge bodies were allowed to run. The year we went to Stock Car bodies started the decline in Group 10 racing, then the motors made it worse."
You would think we would have learned something from the past and not even entertain the idea of running stockcar?
At the time... 4.5" stock cars were huge in USRA and around the country.
And that's the beauty of the IRRA rules... rules for quite a few "retro" type classes. Sure there may only be a couple of regions running them, but they are running them and that's due to rules being available for retro Stock Cars. If Stock Cars were ever to be added to the Sano or R4 races, there would be nearly as many guys running them as the other classes in time.
