Purpose of the Wing

Fair enough on the vague nature of "spoiler" since by definition it's: any aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion.
For all intensive purposes though, Gurney Flaps aren't a great description for what you are referring to. And unless a car has ground effects, the profile of a car's body almost always generates LIFT

The 911s shape isn't ideal aerodynamically and generates a lot of lift. Combined with a large rear polar moment from the entire engine behind the rear axle, rear downforce is needed through wings, which is why base 911s have had deployable wings for decades.
The rear engine layout isn't ideal for packaging diffusers, which is also a problem for Porsches motorsport racecars. I guess those two major inherent issues are reasons Porsche is going mid-engine with their new 911 racecar.

But with anything including women. Sometimes it's the flaws that make them more appealing.

911s do have great traction out of low speed corners and when launching from a start. I agree the front end gets light when on throttle, but due to the polar moment of having the entire engine sticking out the back makes the car inherently less stable when off throttle. Balancing the aero and mechanical grip with these traits is pretty difficult due to the inherent flaw of the engine placement.
911 racecars rely mostly on the wing for downforce since they don't have the packaging room for large and efficient diffusers like most other cars.
That's. Acommon misconception since the Vipers V10 is almost entirely behind the front wheel centerline and the car has a REAR-weight bias of 49/51.
