It is common for a vehicle to be displayed so that its undercarriage detail can be appreciated by the public and judges alike.  To elevate the vehicle means using either wheel ramps or axle stands.  Some entrants disguise ordinary ramps and stands with cloth or material, others construct custom units.  However it is done, the units must be secure and sturdy.  Once elevated, wheels can be removed to display brake and suspension detailing.  Mirrors are often used when the vehicle is elevated.
