Underneath bumper/spoiler damage

1. Recent passenger cars have low ground clearance and larger air-dam under the front bumper.
2. If the vehicle proceeds to end of ramp or knuckle part of slope way with excess speed, air-dam may touch the underneath of vehicle.
3. For some OEMs, specific ramp approach angles might be required.
4. To prevent front under carriage damage, rubber mats and/or proper materials (e.g., wooden & steel plate) should be laid on the entrance or exit of ramps if needed.

Example of rubber mats on internal ramp
