They shot the orange one a year ago, so if they want to keep a secret they can.. Maybe Porsche will introduce the real details so coincide with the anniversary of Post 1..

I am not so much concerned about lap times and performance improvement - whatever he is after is fine, that is a personal goal. However I am deeply concerned about the safety factor. First with balance (for safety reasons), but MORE important with the strength parameters for the suspension parts. Increase/change any of the items mentioned, i.e. downforce through aero, spring rates, wheel size, tire size, and you greatly increase the stress imposed upon the whole suspension system. I would not do any of that before investigating what parameters Porsche has engineered into the stock system. I suspect Porsche has over-engineered the stock system to error on the side of safety. BUT changing the stress levels by increasing the down force, and possibly other items, starts to eliminate that safety margin. Things/parts break all the time racing and those parts are purpose made for those anticipated increased stress levels. I associated with the Corvette Racing team for a while and I can tell you that every single part on their cars has a time certain to it's "usable" life - after so many hours of use they were changed out. Parts are constantly changed on those cars all the time and still they have breakage issues. Pushing the car on the track is a serious business and needs to be approached with as much care, preparation and caution as possible. I just want him to be safe and not wreck the car or himself...
That's obviously more of an extreme as many other forms of racing suspension pieces are checked and if they're not damaged and/or stressed, will go right back onto the car. That being said, street car suspensions are designed for longevity and sacrifice some performance and weight in exchange for durability. I Don't think an RS style wing is would put the types of stresses on the car in which you've pointed out. If it were one of those giant wings that you see in many of the upper levels of motorsport and during an endurance race, then yeah I wholeheartedly agree with you. But for a HPDE event with an RS Style wing, I just don't see forces being too great for the stock suspension. While we agree on some of these points and maybe not others, I want to say. I do enjoy the conversation and like that it's civil and not name calling. I appreciate that and hope you feel the same. Cheers
Best looking snow plow I've ever seen!
Hahhaha that would be so funny if they did that internally as a joke! BTW, that orange is gorgeous! Anyone know what color it is? Reminds me of a Persimmon.

New Wing Tests at Sebring went very well with faster lap times, no detectable difference in understeer, faster corner entry speeds and more stabilized High Speed (146+ MPH) entry with maximum braking into T17 (no more tail-wagging)
Wind Tunnel Testing of the Brumos GT3 Cup Car Wing show raised Wing catching more air:

The Crawford Wing was designed only after a careful intensive 3 Day investigation of my own GT3's construction at their Race Shop. Several weeks of computer-aided Suspension, Engine, and Drivetrain analysis by some of the best Race-Car designers on the planet followed. That is what Crawford does. They design and build Race cars and have been doing that for a VERY long time.
For those of you unfamiliar with Crawford,These Links may be interesting and enlightening:

I appreciate my fellow Rennlisters comments and concern for my safety in this thread, but can reassure them that substituting a more effective raised GT3RS Style Wing will enhance rather than diminish safety, both on the road and track.
Surely the enhanced Safety of unblocking the view through the rear window will be obvious to anyone who has had an unseen child or car appear when backing out of parking spaces, or been surprised by an unseen Police Car, Truck or Race Car appear suddenly behind them.
After 35 years of instructing and racing with Car Clubs and Schools, I have observed that most track accidents are caused by the rear wheels suddenly losing their grip, launching the car into unintended areas. An effective Wing reduces that tendency to “Snap Oversteer” by increasing the grip of the Rear Tire’s Contact Patches, and thus is a very useful safety device.
My student, in his ’06 Viper learned that last Sunday when his enthusiastic throttle foot took us on an unexpected excursion into Sebring’s off-track acres of concrete in T16 Fortunately, only his pride was wounded.

Exactly how I smashed my 997.2 GT3 on the Nürburgring Nordschleife last March...
