The air exiting those vents changes the overall aerodynamics towards back of car, in comparision to normal GT3. There are a lot of factors at play besides just the fender vents but the engineers can do a lot with that particular airflow. If they can manipulate where that air ends up it makes the entire car more efficient which they have done on RS.

AP is a really really really really good spokesman, err salesman. Actually I thought he did a convincing job of talking up the car. I'm really quite intrigued by his description of the aero (compared to RS 4.0) and weight redistribution (new Mg construction, etc). Good job AP and PAG! Stiff competition for COTY in the form of 675 LT etc, so I'm curious to see these reviewed on the road and track. Wow, what a great showing at Geneva. Wish I was there!

I think it's just marketing talk,just as a few other bits and pieces in that interview. Maybe it makes more power,so why hold it back? As soon as someone takes delivery they can take it to a Dyno and verify. And BTW,you can shove as much air as you'd like thru those openings using high powered fans,even at standstill.

Not a secret...but they are quoting dyno'd results of engine while static in dyno room. The reports from Motorsports program is this engine is producing much more than 500hp at higher speeds because of new intake design. The front fender vents are said to be evacuating air directly at both the engine air intakes located in rear fenders and also making rear wing more efficient than in 997 RS.

So let's assume that the car is weighting 1.420 kg including club sport package since it seems standard in Europe the roll cage. Then detract the lighter battery and PCCB and we arrive at "about" 1.392 kg.This seems the lighter configuration until you delete the roll cage.
..
..
Using noted and/or approx weight savings:
Lion Battery: -30lb
PCCB: -40lb
A/C delete: -35lb
Radio Delete: -7lb
That's an additional 110ish lbs that could be taken out of the car if not included in the 3,124lb (1420kg). But I suspect some if not all is already included in quoted weight.

This is the configurator that you come to in Europe if there is no localized configurator.
Not sure if it is the same as the US or not:

The front fender sir vents play a critical roll in down force and works in conjunction with the rear wing. I saw an interview this morning about it- very functional

I would not expect it to keep up with the 997 cup. I drive at Sebring quite a bit and the pros are able to get the cup times down to around 2:05. The 991 gt3 are 11 seconds slower easily and I'm guessing the gt3 rs will be around 7-8 seconds slower.
Don't quote me, this is just an opinion based on previous knowledge.

IDK what the 996 cup time at sebring is, given the time of the 991 gt3, I bet that in the hands of a pro a 991 RS will leave it behind at sebring lap after lap. Must be Lava Orange though
