For this you need to land a jump of 200 yards or over after smashing through a billboard, this can be unlocked with the beginning car the Porsche 911 Carrera S with Standard Burn Nitrous only but will obviously be easier to unlock with a faster and more upgraded car.
There is a very easy spot to achieve this which is in Downtown on 'Gunderson Avenue South'
With a full bar of nitrous drive towards to round stadium at the area marked on the map and boost (
) on the straight before it, make sure to smash through the billboard on your way and providing you land
a jump of at least 200 yards the trophy will be yours
Here's a video to demonstrate.
