Why don't we have 2 classes?
CORR for stock trucks that have an 8.5 limit and have to use kit tyres, springs, shocks etc.
and-
WSORR which is basically an outlaw class where anything goes.
There will always be those that want to come along with all their top gear and just see how fast they can go.
Whereas, the majority of us will be there for the racing and fun, and so will run CORR.
Maybe instead of doing a National series, how about just having 2/3 GP events per year? A bit like the Micro GP's that are organised. Things like Raffles and prizes for many, from the GP sponsors etc. That way it will be more possible to run 2 classes.
I think that way, it will mean more to people to do well in a GP event than to actually have the pressure of doing a full calendar of Nats?
