I agree they'll sell, but it's a big bet by Porsche if the production run is as short as previously indicated. I wonder how many of the over MSRP people will pull out of those slots if the number is confirmed?

The scalper dealers will be depressed if in fact that number is correct.

Anyone have a photo of of a Porsche other than than the 997 4.0, with canards? Still trying to get a mental picture of how you add canards to a pre-existing p-car.
I'm actually debating the idea of using a Crawford wing on my GT3, (just on the track), I'd put my old wing back the GT3 for the rest of my driving.

If they stay on with double stick tape, they can't be adding THAT much downforce, no? Say they were adding 30 pounds of downforce total at high speed: do you think you could hang 15 pounds off of each and not have them fall off? Just curious.

how does this compare to the .2 RS?

I'm not an aerodynamicist but as I recall the function is as much about moving air away from the turbulent wheel opening as about actually generating downforce/reducing lift.
Manthey claim 7kg of additional downforce from their simple wheel arch gurneys (below).
The dive planes I showed were patterned after the ones common on the GT3R and GT3 Hybrid race cars.

The car underbody is a large area, so even a small pressure change results in significant change in total lift or downforce, and most of this force is not born by the dive plane itself. Consider how the flap or elevator on an airplane wing alters lift of the whole wing- a small change results in a much larger one.
BTW- anyone seen springs rates on the RS yet?

As quoted to Mech33 at the show today by *floor people* at the RS exhibit:
"The car is NOT a "limited production" model. They will build it for a certain amount of time, and crank out as many cars as they can. They told me they would build the car through the end of the calendar year, and roughly estimated about 1,000 cars world-wide. They suggested that this was roughly half that of the regular GT3. (I didn't cross-check their numbers) They said they did not have a breakdown by country, but did say that the US typically gets the largest share of cars."

So they're stopping production at the end of 2015? This means a single model year (2016)... I was hoping/expecting two model years (like the GT3, and the 997.2 GT3 RS, 997.1 GT3 RS, etc).

To my eye the RS looks higher & based from the specs (thanks Macca 
)it isn't an illusion; not a fan of that despite that overall it looks aggressive.
So the differences between the GT3 & RS in the motor are;
Crankshaft
Intake system
Exhaust.
Anything else?
Does the RS use rocker arms instead of tappets like the GT3?
