Indoor wise we race at the local club NHMBC
www.nhmbc.co.uk/
Its mainly touring cars that race 1 or more heats of stock and modified usually then you get the buggy heat which is ace if you like fast high grip carpet
and maybe one or two jumps.
but the norm for us is york of road car club in door and any outdoor track like Batley, Bury Metro basically anywhere in the north east/west area.
