This is a one Day Challenge - don't miss it at 18th April
You have to drive a (short) distance with two wheels.
Good Locations are the three ramps at the Airport.
Just drive minimal diagonal and not to fast over a edge of a ramp, and you should get a two wheel skill, this skill has no cooling down time (or a very short). You have to do this 3 times.
When your to fast you will performe a barrel roll (does not count).
