Porsche does not approve of lowering a vehicle height. Lowering a car may constitute a violation of Federal Motor Vehicle Safety Standards as well as a violation of various state laws regarding height of lights and chassis height.

Lowering the vehicle height may also result in damage to fuel pressure line, which could cause a fire with the potential for injury.
