Worst thing I did? Race foolishly on the streets. Never, ever, ever, ever engage anyone in a race on the streets, even if it is at a stoplight with zero traffic. You race, the other guy crashes his car and dies, and you go to jail for manslaughter. Life over. Also, the fact you're driving an Integra automatically means you're guilty to the cops.
Best thing? Getting involved with SoloII and HPDE's. Lot of great guys there. A bit $$$ for the average student though.
