Some things I've learned from the track.
1. Listen to your tires.
2. Brake early.
3. Don't overestimate how fast you can enter a turn.
4. Be on the throttle or on the brakes. Don't coast.
5. Be smooth with your throttle pedal.
6. Don't lift throttle in a committed turn.
7. When you go off, don't try to be a hero and fight momentum in an attempt to get back on track. You'll flip.
8. Don't drive on the street like you do on the track.
Umm... none of that is from personal experience, of course, oh no no no!
