Join your local PCA or SCCA and run as many autocross events as you can. Great way to learn car control, improve as a driver and meet some great folks. Usually at the PCA events there are instructors that can REALLY help you learn your cars limits. Don't take this the wrong way but just your asking on this forum what happened tells me you are NOT ready to go out on a road course at high speed. Get as many AX's under your belt at relatively slow speed and learn your car, suspension, brakes and tires plus yourself ! Then go out and get on a road course. Ultimately the goal is to have fun, be safe, become a better driver and above all return home in one piece
