It looks fantastic!

It almost seems out of place to ask, but is there any verifiable increase in functionality or is it purely cosmetic? Also, if there is an increase then how would that affect the front-rear balance at speed?

I ask because on my 78 Porsche 911 SC the addition of a rear wing without a front spoiler resulted in some unwanted and rather scary behavior above 100 mph.
