Find the car launch in picture one. Then set cust off your board when the car launch is at the top. Now ride over to the boost and off your board goto cust. Make sure that the launch is still up when you goto cust. Now ride it back down then off your board jump when at the bottom. If done right you will launch really high and when you land back on the car launch the car wont be there. (I think that the car lowers before the ground actually lowers)
