+1 to everything Loren says, and an extra shout out on the subject of braking managment.

If you have a fast car and fast tendencies sometimes one of your most critical limiting factors will be how fast you can enter a turn, which often means putting your car at its braking limits over and over again.

Even if you keep the car in its handling limits you may find it only takes a few turns or a lap or two depending on your driving and the car, before the brakes will start to fade or boil. This can put you in a very dangerous situation if you quickly enter a turn and find out too late your braking capacity is gone or find the pedal going to the floor.

So in addition to trying to figure out how to properly navigate the course, don't forget that if you are fast enough and your brakes arn't ginormous, you may need to slow your pace and better manage your braking technique.
