Has anyone participated? It's about $450 for entry for two days. I was wondering if that's worth it.
Depends on the club. BMW CCA, Speedventures or Trackquest (I think) are the best. Go for it, you'll learn a whole bunch and become a much better, more confident driver.
This is the first "mod" I recommend to anyone - first fix the driver, then mod the car.
