rules for oval

being a sedan oval guy has been tough this year our times are almost as fast as the pan cars now and i would like to see some rules set down i know we talked about this week but i thought it would be good if some people threw down ideas here i personally think we should have two classees stock and open stock would consist of 27trn brushed and 13.5brushless rubber tires. open would be exactly that open to anything just an idea
