Asphalt 8: Airborne

This is one of the easiest achievements in the game. Start up a CLASSIC race (Like Nevada Classic, the very first race), not an elimination or another type, from what I remember, the achievement won't pop there.
After that hold the brakes for about half a minute. The other racers should be way ahead of you, and then drive to the finish line, and make sure you remain in sixth place.
