When flying through the air press, hold Circle and tilt the Analog-stick in whatever direction that applies to the situation. For example, if you are going to land on the rear, tilt the Analog-stick Forward to level out. Some cars have the ability to do spins, flips, and spinning flips. Note: Bikes and trucks cannot do the aerial stunts. Tuners are recommended for these stunts, though weight transfer works for all vehicles.
