After using a few different trucks the ones with the van body styles worked better. So I got it with Boogey Van Grave Digger.
Quick Event
Circuit Racing
Gecko Flats Airfield
Difficulty: Beginner
Event Length: Extended
Truck upgraded to T5 for acceleration and top speed.
As you get to the big jumps try to flip and land on your roof. That will knock off a lot of it. When you get to the finish line hit the pole with the dead center of your front end and it will knock off other random parts. Hardest bit to remove on GD was the roof bit but just landing on the roof enough had it come apart.
Also you can't use 2 controllers, gotta be single player.
