I'm not the expert, CosmosPower seems to be the guy here. I went to the last one at the bus lot and it was a good event. Course times around 90 seconds and hit the rev limiter once. 8 runs total. 4am and 4pm runs. I liked the setup and there were a lot fewer cars than ER or SCCA. Non BMW classes are pretty non specific, i.e. all year model Miatas and everything else under 2 liters in the same class except Elise and S2000. I might see you there.
