Pete I was there yesturday and I liked the car. My freinds liked it too and said it was loud. I heard that the driver of the S2000 was sent to the hospital to be checked out because he said he was felling dizzy. Thats all I know about him.

The '10 RS "far more stable" than the '04 GT3 ... that was just the pure talent of the driver ... : )

I hear you now ;-)
You are right about the kind of noise.
Just drove 4 hours straight. The car is very loud, much louder than my GT3 with sharky.
The Sharky exhaust is a bit louder, but not much, bet the RS lets in all the other noise from the tires, engine and maybe even wind a lot more. I could swear the rear window was cracked open an inch.
Still, with the plug plugged in and sport mode off you can keep it livable quiet if you stay below 4K RPM..

I think it's a combination of engine noise, induction and exhaust.
At 72 mph (slow enough to pass a speed trap in a 65 area) the cabin noise is absurd. But, fine by me, the car is not meant for touring.

Agreed. After a day at Laguna with -2.0 in front and stock rear, I think the car needs better front tires and tire pressures, not camber. I'll keep tinkering, but I think this 911 is an entirely new game, not just an incremental adaptation of previous 911 metrics for suspension and tires.
"My sense is that most reviews of the 10 GT3 understate the changes to the suspension. One test that contained a more thorough detail of changes was published in 911 & Porsche World magazine. If you search online you'll find part of the article but not the full suspension change detail covered in the magazine itself. The comments on suspension changes came from Karsten Schebstad, who works with (for?) Preuninger and is in charge of Development of Performance GT Derivatives. I don't have a scanner to post the whole article but an abbreviated summary of changes noted includes:
Altered pitch, lowering the front 5mm and raising the rear 4mm.
Raised outer bushing and track rod end locations on front axle 10mm (in line with GT2)
Reduced agility of front axle (considered too excessive) by lowering front roll center from 94mm to 55mm and raised the rear from 24mm to 30mm.
Overall roll stiffness unchanged but ratio front to rear changed significantly (from 49/51 to 43/57) by making front anti-roll bar 30% softer and rear 30% stiffer.
Front toe-in reduced from six minutes to zero.
Negative camber slightly increased at front and slightly reduced at rear, by 10mins in both cases, making it minus one degree, 30mins all around.
Damping characteristics changed to increase initial response.
Rear damper bushings stiffer.
Stiffer springs.
Again most reviews only picked up on the anti-roll bar and spring rate change. I can't speak to the validity of the everything listed above but the source seems credible."

Thanks, good stuff.
I certainly feels different, even on the road, but not stiffer at all, it feels softer to me.
When I corner balance it, I think I will just lower it overall, but keeping the factory pitch and allignment and see how the tires wear first, and mess with sway bars only.

Pete:
Very nice meeting you at the track yesterday. I was the one who had the white Cayman S. I tried coming back for a demo of the sport buckets but either you moved or were on track every time I looked for you.
After seeing the car in person, I can say it is absolutely beautiful in person. I love the color and the graphics on the new car. Now I just have to save for a couple more years. Enjoy the hell out of your car. Buttonwillow is a great start.

This is a true statement...haha
It was quite comfy to me on the long trip. Not jarring or harsh at all. Just rock solid.
