Amatuer race series ?

Let's say you wanted to do something a bit more in depth than the track days and wanted to do a race event series for a season, what would people recommend at an amateur level? Nothing too serious but something to build up for?
I'm not taking time attack etc but something like a clio season etc?

Ive never looked into it really but would be interested in learning what's out there :jase2:

thanks guys
 
Thanks Chris, it's something ready for next year when the cars built...I've got a friend that did time attack last year and he had a blast! Get a smaller one out the way then might venture into bigger things!
 
You could also look at Springts/Hill Climbs too, it isn't circuit racing but it is competitive and not that expensive to compete in.
