Isn't technology fun ?
Some issues with published Supps (groups & classes) are being addressed, as we speak. Somewhere between Racechair's kitchen table & "post to the web", an early version of groupings and classes wiggled its way in.
So -
There is no class called "ST". Put your welders away.
STL is being added to Group 5.
SM2 is being added to Group 3.
Group 6 (SM, EP, FP, GTL & HP) is being eliminated, and a new group, to follow Group 7 on the schedule - Group 7A - will be added. Group 7A will include SM, EP, FP, GTL and HP. The mating cry of the wild "double dipper" was heard.
Motorsportreg does not reflect these changes at this point. Don't panic.
