(The opposite happens when you lower a car* - Cd, CdA and Cl all tend to decrease. *Road cars, with normal ground clearance.)
I know of at least one University study at MIRA in which the opposite was found to be true.
I'd lose the word 'will' and replace it with something about 'statistically significant.'
