New GT3 on street

Since my investments have ruled out a 997.2, I am stiffening the springs and shocks with the Damptronic B16s. I wonder if Porsche will be selling the magic motor mounts and what the price might be? If they are available for a reasonable price, I will be happy for this year. Unless I also find a set of GT2 seats...

If I were buying a new GT3, I'd definitely get the active mounts and the lift system.
The mounts are a brilliant idea. I hate it how everything resonates and buzzes at 3,000rpm in the interior and how the engine feels coarse until 4,000rpm. This is due to a harder than required street mount and a softer than desired race mount. My 993TT was much smoother in this regard, but the engine moved around a lot in that car on the track.
I have full poly engine mounts on my racecar and can tell you that it introduces a whole suite of problems on a car that isn't checked over every week. Everything, and I mean everything, comes loose due to the vibration.
I'd love to have a mount that transmits less NVH through on the street, and that stiffens up to produce less movement on the track. I love advances like this, you get to have your cake and eat it.

Agreed. It suggests they didn't have enough R&D time. Or there's some engine strength issues. Theoretically, the 997.2 case is a lot stiffer ... are they getting ready for DI in that case?
"993TT was much smoother"
Again, agreed! When I start the 993 (usually standing outside the car reaching in) the exhaust sounds like it's ready for a fight, but when you sit in the car, there's no NVH. And my 993 has solid mounts and hard bushings. I haven't had "nut and bolt" issues, but it is held together with loctite and I don't track it much -- to my shame -- at all.
"The mounts are a brilliant idea"
Hardly brilliant (since it's a licensed technology, I think from GM) but now that Porsche is using the electromagnetic "goop" technology, I hope it tells us that's the harbinger of the next PASM. I'm not looking forward to a 911 that uses lasers and sonar to "read" the road surface and tweak electronic goop dampers, but if they're going to put active suspension in a GT3, let it be the smart stuff (sans "forward looking" aperture radar, etc.) at least it will be light and fast.
I want to make this promise to myself -- the next GT3, I'll pull the PASM and put some good, simple, old-fashioned coil-overs on it.

Carrera GT, some impressions...
IMO, the 993TT was horrific on a track or otherwise. Vague steering and vague handling to the nth power, to be blunt. A failed marketing experiment in 4wd and the result of insufficient R&D investment (merely better comfort than the 964's). With 2wd, perhaps proper tuning would've overcome its enormous compromises.
The 997, be it GT3 or otherwise, is light years better dynamically. The 993 TT was, as the professor so eloquently put it -- great for a trip 'round the block to pick up a bottle of milk. In all other respects it was a handful and not competitive, much less confidence-inspiring by any measure without loads of modifications.
Of course, back in the day, it was ok, but we're speaking in terms of present day. All of this just MHO.

why not just get solid or semi sold motor/tranny mounts. they make a big difference in feel.

man can't wait too hear with respect to that dynamic engine mounts- too harsh on soft setting and too soft on sport setting. I'm waiting. I check off on that option and lift option too. For u guys to discern engine moves too/fro we got f1 drivers out there. Mike

Hey SCSS98, glad to see you are using the pic I took of you at Summit Point from last year as your avatar! Looks pretty cool. It was fun to photoshop it. I immediately reccognized it. Nice to see some pics go to good use.

Gents, I say this with some cheek but I think we need to harden the f#k up about the rear wing...
Unlike many other manufacturers, Porsche put it there to fulfill a purpose... increased downforce, not bling-bling... As was clearly indicated in the podcast interview on DR republic (link in other thread), downforce was increased nearly "3" fold... thats a big difference (more so than even the previous generation RS) and the only way to achieve it is through a combination of surface area and shaping... A concern with the 997.1 was downforce and high speed stability and so many guys here have upgraded splitters and wings for the track which confirms this... they've attempted to address the issue... Who here has seen a discreet wing on an F1 car or a touring car??? I think not...
Simply put, it was used to fulfill a purpose-downforce, not for show... and the size is the compromise...

for this significant improvement in F/R downforce ...

Now I just have to find out how much I can peddle the 996 GT3 seats and the unused stock seats for.
