If you were having a little trouble with this like I was Try doing this:
Go into the Garage > Tuning > Stunt setup
Suspension Height - Lowest
Suspension Stiffness - Stiff
Suspension Dampening - High
Gear Ratio - Short
Torque Distribution - Back
With this, I did it first try. Just reverse a little and punch the gas then pump the trigger accordingly when your front gets too high.
