Quantifying the aerodynamic impact of lowering a car? (drag coefficient Cd)

I'm aware that lowering a car can improve the fineness (Length to height) ration, and also drops the cD of the car..

Its also not normally an economically viable thing to do..

However...

The golf's suspension is shot- very little damping up front, and the bottom arms are clanking. It will need replaced sooner rather than later.

there are two options (both roughly similar in cost..)

1. Replace with standard parts (dampers/springs/arms)

2. Replace with a coilover kit to allow for a 40mm drop


Would the impact of lowering provide any tangible savings that I could use to justify the work?

or am I better just going with original/pattern parts?
