To determine whether your car is tight or loose upon entry into the corner, roll through the corner at the beginning of practice and note the turn angle of the steering wheel (tape on the wheel is a good way to gauge this). Work up to maximum speed through the corner, again noting how much steering input is needed. If it is much more, the car is tight. As an example, on data-logging IRL cars, a driver usually turns the steering wheel 8 degrees into the corner. If the driver gets to 15 degrees, the crew will bring him in to make chassis changes for fear the rear end will break loose, crashing the car in the middle of the corner, since the front has so much grip.
