lowering to reduce drag

Reduced height springs are used primarily to lower the vertical center of gravity in race cars to improve handling in circuit racers Not reduce undercarriage airflow.

Undercarriage air flow is reduced somewhat but that is better achieved by air dams and chin spoilers in the frontal area.
Drag reduction is better achieved by the use of undercarriage slipstream modifications by using bolt on flat panels of a suitable materials.These can be attached in such a way as to reduce he under carriage air mass ( road clearance ) by the use of stand offs. this requires no modification the suspension or ride.

The cleaner aerodynamics also contribute to lower overall drag for better performance and gas millage. If the panels contact the ground they are a cheaper sacrificial donor than your exhaust system or other expensive components.
