Are body modifications like flared rocker panels and ground-effects spoilers just for looks, or do they have benefits like increased traction and/or reduced drag?
I'm thinking they just change the looks.
I've been comparing the Boxster S to the Boxster S Anniversary Edition and notice that the anniversary edition has all the options that increase performance, like stiffened suspension, shorter gearshift throw and larger wheels.
But no aero kit. And I postulate that if it helped performance, they would have included it.
However, the anniversary edition also includes the PSM (Porsche Stability Management) which probably *reduces* performance in some situations (in the nicest possible way, of course), so my posit could be wrong.
Sorry to bring up nitty-gritties. I am in a phase of life known as Boxster Waiter and have 3 more weeks to kill before taking delivery of a Boxster S Anniversary Edition (silver exterior, black top, dark-grey interior, Bose, CD changer, cruise, and seat backs painted silver). :-)
