When did they start putting an oil cooler on the rear end of a car ??? :lol: I think you got an e-mail from a secretary at DC, not a tech...

The rear spoiler is functional... Though I don't have the exact calcs. for the down force created by the wing... As I have not seen any wind tunnel tests... But based on the front/rear weight differential, I would guess the wing produces enough down draft to keep the *** end of the car on the road at speeds over 100mph...

So unless you're driving those speeds, it would be cosmetic... Unless of course they have a hidden little oil cooler in the rear turn signals... :lol:
