Autocross is next saturday at Lovelock. The next (and last) weekend at stead is the first weekend of October. Full schedule
here ... look for all the "solo 2" events,
The stock WRX wheels and tyres are bad for going fast ... but great for learning on. I did several events on those last year, no problems at all. You just need to pump them up a few psi over normal pressures to stop the sidewalls rolling over during hard cornering. Lots of us have electric pumps so you can pump them up at the event.
