There are dozens of organizations that run HPDE events. One of the very best is: nasane.com/ They love newcomers, and have great instructors. You can check all the HPDE events out at: www.motorsportreg.com/ Just sign up, make sure you read and comply with their tech inspection sheet, and show up. It is loads of fun and addicting. If you're driving a faster car like a Corvette, best to replace brake fluid with hi temp racing fluid, and replace the pads with racing pads.
