Thanks. The E 30- 6 runs CCO, the E36-6 runs CCX.
The M44 and 42 cars are slow enough to run the CC class. Turn in nice tho.
Each class should also have a tire max, but Chump does not. maybe CCU 225, CCo, 245, CCX 275.
The Demoines region shows to have the ITJ and does Portland . But both websites are a little poor as far as finding any rules.
