In this paper:
Evaluation of the Aerodynamics of Drag Reduction Technologies for Light-duty Vehicles: a Comprehensive Wind Tunnel Study 2016-01-1613

They tested a range of cars model year 2013-2015 and found a 2-3% reduction in drag by lowering the nose by 20mm and a 5-6% decrease with a 40mm front and rear drop.

Based on this I would say definitely test first. Sandbags or otherwise. If you ever load the car down the rear will sag and have a reverse rake if you level it out. If that is something you do often it would be something to consider as well.
