Various elements laid on a track to test your mod car's suspensions : speed reducers, kickers, waves, cones.
You can start with the car floating in the air like it was lifted in a garage and watch the suspensions fall. It can help notice problems. You need to press start then press escape then restart, then F5 to rotate around the car.
I hope you find a use for that !
