I suddenly realized that somehow the full rear picture somehow makes the tail look wider than it actually is. It is 54.5" which is only 3/4" longer than the GT4 tail per side. Here are three photos that provide more perspective. It is over 5" inside of the outer edge of the tail light. I will be selling for $875. The car is a TPC turbo with 428 hp at the rear wheels. Quaif differential, RS steering wheel and H&R suspension.

Cool stuff. One thing to consider with the side scoops is that the function of the respective vents on a 987. On the 981 they were changed to both be intakes, and a scoop will aid with the "intaking" 
On the 987 the driver's side vent is an intake, but on the passenger side it's an exhaust vent for the engine compartment. If you stand next to your car on a hot day when the fans come on you can feel them blowing air OUT of the right vent.
It may well be that while diving, forcing air into that vent will make sense, and while stopped, the scoop won't have much impact, but if the fans ever come on while under way, a scoop could be pushing air against the fans. Again, no idea if that would be a problem.

You are right about the function but it is definitely an intake not an exhaust site. There was a big forum on this back in 2006 and the factory definitely designed it and the intake scoop as an intake. Yes, when hot it does have a fan but it is an intake not an exhaust and these scoops are designed to help reduce temperature in the engine compartment. Jon 954 931 0319

Hrm. I track my car, which means I spend a fair amount of time in the garage sitting next to the toasty car after it comes of the track, fans blowing away. They are blowing air OUT of that location. Maybe they are smart and change direction while under speed , or when the key is in the car??? It makes sense that while stationary they would want to vent off the top of the engine bay and not try to force hot air down and out the bottom. I'll try to take a video of it next time (in a couple of weeks).
When the car is off and the fan is off, it's not unusual to feel air coming out of the right-side intake. That's just natural air circulation, coming in from under the car, being heated by the engine and then escaping anywhere it can.
But, when the car is moving, those ports on the sides of the car are definitely intakes. And, the cooling fan on the right side should be wired to assist the natural intake by pulling air into the engine compartment. I've had two 987s prior to getting my GT4, and both of them would pull air into the engine compartment when the fan was running.

GT4 type wing on a 981 GTS
Hello All -
I purchased the GT4 wing from Jon at Composite Concepts. First off the wing arrived wrapped and packaged very well. It will not get damaged in shipping unless something really crazy happens. I have purchased quite a few carbon parts for lots of different cars and the carbon on the wing was excellent, perfect weave with no flaws. It's a very nice Carbon piece.
I installed the wing this weekend without issue in a couple of hours following the directions provide by Jon.
Everything went together without a hitch. I did deviate in only one aspect as I decided to attach the front mounts with rivnuts since I had the right sizes. I'm sure the supplied hardware would have worked just fine.
I am on the fence about painting the winglets body color white. A decision for another day. I will also get the new GT4 winglet design that Jon is manufacturing now.
Thanks to Composite Concepts and Jon for the great wing at very good price. I also have a GTR and a few others and you will not touch a wing of this quality for the price on those cars.
Here are a few pics of the car with the new wing.

Composite Concepts GT4 Wing
I've also purchased the Composite Concepts GT4 Wing for my 987.1 race car and have nothing more to say than its the best wing for the money available! Install was straight forward and it honestly looks like the stock OEM wing from Porsche for a fraction of the actual cost. Jon was very professional to deal with, answered all my questions and shipped the same week it was ordered. No hesitation in recommending to anyone interested.
