Has anyone turned a 981 into a more track/race car looking setup. Im curious how the 981 looks with a big/cup wing. Havent seen any really yet.

John, Nice looking car and build. I'm curious about how you chose this wing. The spy shots of the GT4 show a different shape wing for the Cayman and I was wondering if this wing is a better fit for the Cayman body?

What's the rationale of having a T wing like that? I am not an aerodynamics expert but...
Dont you want the downforce on the sides of the car near the tires for more traction as opposed to the middle of the car?
Specially when turning

The vertical parts obviously give no downforce. They may help in cornering a tiny bit for their sideways grip in the air. Or they're just there for looks.

As for the horizontal part, it doesn't help if you move more surface out towards the sides. The car is mostly rigid so a symmetric change makes no difference. A bigger factor when placing the wing is probably the shape of the airflow created by the rest of the car body.

We did a fairly extensive buildout of this car in March. We are however prohibited from professionally campaigning the new 991 or 981 for that matter, so this is just a track day / DE car.

How come?

300 miles on the OD - although these have probably not been "easy" miles :)

This is a 987 and not 981.

Look at the TechArt thread here and the GT4 spy photos for some additional racier wings.

We actually installed the 3.8L x51 engine in this car. I know it's seemingly expensive but this was a race car that Geoff invested in to create the most built out Cayman for road racing. Big slicks. Big brakes. Big power. Hopefully someone wanting a 450hp 3.8L Cayman race car will take it!

My choices made in March 2014 were based less on preference (the base at least) and more based on availability. No one had anything at the time and while im not a fan of wing bases and while I'm sort of a fan actually of a lack of a wing base and seemingly factory uprights, we went this route because at the time we didn't have options so I had to chose the Techart base; not preferring that Techart wing design I chose the Crawford GT wing similar to the one we all ran in the Rolex 24 and Rolex Series. Crawford has been making real carbon aero parts for the highest level of motorsport so it was an easy choice due to an existing relationship and the fact that my go-to guy was not done with his 981 parts. NOW, my favorite maker of wings and body parts for Caymans, Getty Design in So Cal has already started and is mostly complete on his 981 parts. Mark's RS style wing that you see on most 987.2 Caymans should be available by now. I can post pics below of the Getty style wing on a 987.2

Also, below is a wing/upright design on a customer car that I really like that is more similar to the GT4 setup. If I could ever do all the projects I wanted, I was going to have an active wing that the owner can raise and lower like the factory one but bigger!!!

How come?
It's a long story that I could probably shorten by saying "they did not want us to" but the ultimate and sad answer is politics. Over the last decade Porsche Motorsport has tried to stop teams like us from building street cars into race cars by sending letters and alluding to verbal threats. If you follow our series you will know that a GT3 Cup Car does not fit racing against 400ish HP street cars so the series never allowed the GT3 Cup purpose built race cars and furthermore never allowed a manufacturer to dictate what teams can and can't do when they were not supporting them with funds or parts. During the series merger the staff changed and the new regime had the quiet voice of Porsche in their ear when we took a 991 street car and enhanced the safety of it by adding a 1.75" * .095 mild steel cage in it, and anchored to the remaining sheet steel in the unibody of the 991 and tried to homologate it for GS racing. We did the same safety modifications we had done to any street based car over the last 10 years and bells and alarms went off, I got calls, emails and ultimately it was said that the "cars are not safe based on my improvements."

In a matter of months, the only revenue source we have ever had over the last decade was killed dead in its tracks. This is the single biggest reason we were forced to find another way to survive after 10 years of promoting the brand; if you consider the fact that we campaigned Porsches for 10 years culminating in Porsche's winning a Driver Championship a Team Championship, 2 Manufacturer's Championships and a Rolex GX Championship against the Mazda factory, it makes the ginger hairs on your neck stand up. I need to remind myself to shut up and go back to work and bite my tongue and keep quiet but sometimes I can't. Sorry for the venting folks!

On the aero: no difference in handling, loads or downforce between center and side supports. If side supports are used they can double as end plates (see last iteration of Lotus Exige S). The aero trades are pretty complex. Here's a snippet from COMPETITION CAR AERODYNAMICS by McBeath.
