Proper Driving Position
Optimal seating position
You want to sit low enough so that you just barely see the top of your hood. If you have a long torso, you may not be able to get low enough, so just set your seat as low as possible.
The top reason you want to be low is it allows you to see further ahead, which is advantageous when you’re planning out your racing line on the fly. This may feel uncomfortable at first because you can’t see directly in front of you, but when you’re moving so fast, it’s more important to focus on what's up ahead.
Another reason you want to be low is it decreases the center of gravity of your car, which improves handling.
This one is easy - recline your seat to a comfortable position. No gangsta lean like the picture in the right, but also don’t sit stiff and upright.
Slide your seat back to a position where if you fully press down on the pedals with your feet, your knees are slightly bent. This ensures that you have good leverage when working the pedals.
Steering wheel position
Proper steering wheel position is important because it allows you to employ proper steering technique, which will allow you to apply force over the widest steering range possible.
How far should the wheel be from you
Place both hands on top of the wheel with your back to the seat - your elbows should be slightly bent. Most wheels can be telescoped in/out via a lever at the side or bottom of the steering column.
How to hold the wheel
Most professionals recommend holding the wheel with your hands at 9 and 3 o'clock because it lets you steer almost 180° in both directions with control and speed.
This means you will almost never have to take your hands off the wheel while steering, which is very advantageous because 1) you know precisely how much you've turned the wheel, and 2) you save more energy.
