Two more thoughts based on my track experience. First, be sure your
oil system is up to any prolonged G's you'll pull in turns or braking. You don't want the engine to go dry when the
oil sloshes in the pan. Second, be prepared to resist the urge to catch the car ahead of you or stay ahead of the car behind you. That's a sure way to exceed your capabilities. I think of it as trying to push no more than 80% of what I think is possible in terms of braking and cornering. ... One bonus thought. Keep in mind that the place where drivers of most high power cars lose it is exiting the turns. It's tempting to lay down on the gas while completing the turn and exceed the grip in the rear tires. Instant oversteer.
