The Jim Russell Championship Series has been running for two seasons now with the F3-based Lola. The series doesn't seem to be terribly well supported though - biggest grids this year were 8 cars.

2008 champ was Brett Smrz, who competes with an artificial lower left leg. He finished 4th in the FF Kent Festival final this year.
Oh and if anyone has the final 2008 JRCS point standings please post them!
