I don't mean this as a commentary on this wing, but I'd like to see the data that the 991 GT3 wing doesn't really do anything. It's hard for me to believe Porsche would add something so ostentatious without it providing real improvement. That's not really what Porsche does.

The GT3 Wing is an improvement over no wing at all.
But the larger wing that will be used on the GT3RS is a much larger improvement.
I fully understand that our GT3 performance is constrained by both manufacturing costs and the necessity for leaving room for the improved and far more costly "RS" models of the basic GT3 which will follow. If an alternative performance improvement is available now, I saw no reason not to develop it - hence my enlisting help from Crawford's Racing Group.
More Rear downforce also reduces the tendency to snap oversteer and, IMHO
enhances Track safety.

Did Crawford also make a revised front splitter? The reason I ask is that, on my prior 997 Cup I installed the Crawford Grand Am wing. It worked great when paired with the Crawford Grand Am front splitter. But if you used the Grand Am wing with the OEM front splitter, the car pushed like a pig.
Just food for thought. If the rear wing increases rear downforce appreciably, then the balance is likely to be off. Porsche is very unlikely to sell a car to the general public that has a tendency to oversteer due to an imbalance between front and rear downforce. If anything they'd do the opposite (for safety/liability reasons).

I think what needs to be understood is that the GT3 is a street car, is styled like an aggressive street car, but happens to have the heart of a race car (engine power on par with prior CUP cars), and can provide us all with incredible on track performance, yet has limitations due to it's street design. In general, Porsche does develop a car that is designed with aero to avoid snap oversteer at speeds greater than 130 or so, and it is called a CUP Car. But no one here besides MOOTY would drive one on the street. The RS will be a "closer to CUP car" design, and I tend to thank the trailblazers with these cars, like SAMfromTX and FastLane for their efforts to make this STREET car safer and faster on the track.

I never said the GT3 OEM Wing didn't do anything. On the contrary, If we can believe Sport Autos's measurements, it generates 65 Lbs of downforce at 130 MPH. For a true Racing wing, that is VERY low - which is why Race cars use larger more effective wings which allow them to reduce lap times by going faster around corners. 65 Lbs @ 130 This means that on a 65 MPH average corner (half the speed) it would generate only 16 pounds of downforce, (1/4 the downforce).

One of the links that FastLane posted shows the wind tunnel testing of a CUP car, and you would be surprised to see how the shape of the 911 directs airflow. That wing needs to get high to find clean air!!

Stated another way, Crawford might sell a rear wing with no matching splitter to street drivers. But it isn't going to sell a race team a rear wing with no matching splitter and say, "you're good to go."

Really appreciate all of your assistance and thank you so much for sharing the drawings. Much appreciate. You are a true gentleman and first class act. People like yourself are one of the reasons, I enjoy spending time on the Rennlist. Thank you so much and God bless you. If you ever need any assistance in manufacturing or fabricating any custom parts for your GT3, please don't hesitate to contact me. It will be my pleasure to assist you. Mark

LOL. Lane this is so true. Unfortunately these young engineers think they are God's gift. I love their confidence but every once in a while I make a point to bring them down to earth. This should be an interesting project. Hopefully they don't nag me too much, to drive my car at the track to test out their proposed design ![nono](https://rennlist.com/forums/graemlins/nono.gif)

My Wing project for the Street GT3 started out as a personal project based upon
the outstanding performance increase of the Crawford Wing on my GT2 993 Race Car, the last of Porsche's Air-Cooled and Turbo-Charged Race Cars. It was far above and beyond what Weissach had delivered to me and kept the car Podium competitive for 10 years in serious Club racing, which I thought was pretty remarkable.
I was delighted that Max Crawford was willing to assign the R&D resources
that he did to a street car project after decades of building professional Race Cars
for well-financed International Race teams and be willing to further extend those
resources to my fellow PCA Club Members and the Rennlist community.
I sent an E-Mail last night to Max Crawford asking for pricing of additional "Wing Kits" and received this reply:
The wing kit comprises;
· One 60” element with a 12” cord
· One 3/8 gurney that is removable
· Left hand and right hand wing end plates
· Left hand and right hand aluminum mounts with carbon covers
· Hardware for the wing to the mounts with an adjusting tool.
· Brake lights in the back of the mounts with a wiring loom
The price of the kit is $2960.00.
Thank you again for your continuing interest and kind comments, and Best Wishes for a Happy and Healthy Holiday Season.
Lane

^Wow, great deal for such a nicely engineered piece!

Great price, I've always run all cars with Max wing + Gurney flap.
I'm partial to the nicely shaped .2RS wing and 991RS wing as opposed to this look, CUP and .1RS but it should work great.
Looks like a great option for someone liking the CUP look and / or more down force.
For me the biggest advantage would be that I can see out the rear window!

Lane. Being a 993 man at heart always loved your old ride and never thought that wing was outta place - just need to look at the spiritual predecessor to the RSR ( we all go Gaga over) - the 993 GT2 EVO to realise it fitted right in. Short memories we have...,
