same with mine... though i'm not sure if the pop/creaking is from the windws or somewhere else.

They are definitely NOT seam welded. As another poster pointed out there is always some flex in anything. Look at it this way...would you rather it flexed or cracked?

My 07 makes the occasional "crack" noise on uneven pavement, seems to emanate from the S/R area. Of course the front springs boing most times I back it out of the garage. I think it's the stiff shell intracting with other areas of the car that flex more.

Moreover, I take the fact that GT2s and GT3s lift a wheel on the way into some driveways as a sign that they AREN'T flexing — or, more accurately, flexing as much as something else would. Put under load, yes — but so many things put your chassis under load and I'm not sure you can avoid that unless you want to park the car and look at it. When I lived in SF, various 996 and 997 Carrera press cars would never lift a wheel on the way into my (fairly steep initially) driveway. The GTs all required a two-step entry/exit to avoid scraping, and all of them lifted a wheel quite a bit. For me, that confirmed that a) the non-GT suspension was softer and there was more effective travel and that b) the 996/997 shell was very, very stiff.

Yes, chassis are wear items -- a subject no one wants to address. That said, I know of an awful lot of 1970s Porsche street cars with 100,000-300,000+ miles that feel structurally sound despite starting with vastly inferior structures when compared to your 997. I suspect (hope?) you'll wear other things out on the car long before the tub!
