The setups are created by Laland2k according to data taken from the game files.
The car’s showing: no shaking; enough grip, without too much sliding, little tyre squealing when turning corners, smooth landing after jumping, no sudden spin-outs and unwanted heaviness with "Ram" powerup turned on.

Tip: to fit the top overall in the class, raise the level of details around the edges. Starting with engine-tires. If not enough, raise the induction-brakes. This method distorts the behavior of the car minimally.
