Excellent posts R32 & ADC...
To the OP, you may want to check out NASA's HPDE/Open Track calendar for events happening near you.
They put together some really great events that are safe, educational, and more fun than a barrel of monkeys.
Afterwards, you'll drive back home a better driver with newfound skills, and a lot less urges to try risky/illegal things on the streets. You'll drive safer on the street and have a better appreciation of the skills you've learned, not to mention knowing your car's handling capabilities in a more intimate way.
