They look great, but I'm quite curious and knowing how much you test your products, how much extra down force can you achieve or is there more to it then that?

1. A CFD analysis will help to show benefit and an approximation of front rear downforce, the issue is that there are a TON of assumptions in a CFD analysis, ride height, rake
2. Monitoring the 991's shock travel sensors will provide some real world data as well. I have a DSC box that allows access and logging to these sensor pretty easy and plan to do a before and after.
Gurney's do add additional downforce without having to increase the angle of attack of the rear wing, so those that are dialing in high speed rear grip vs straight line drag will gravitate to a gurney.
For the 997.1 and .2 crowd a gurney was a given, especially for the RS.
The bottom line will it reduce 5 seconds from your lap times, unlikely. Will it give you another toggle to dial in the car with yes.
I still plan to get data but will likely be spring before I can get anything conclusive, unless we have really dry winter!

Gurneys work or they wouldn't be on CUP cars.
Gurneys dont void warranty.
With more front down force it makes the car faster.
Ive proven that (to myself) on the 997RS.
991RS has plenty of down force but you can run less wing with a Gurney.
Im in.

Mr. Adair: Matte Carbon RS please
I have been working on my home to coffee shop time, this should give me the added down force I need in the 45mph straightaway between Oak and Elm street...
