Excellent point, thank you. Since the engine is now out and being replaced wouldn't they have to now align it?

Clutch chatter is more than 90% of the time caused by an issue with the friction surfaces of the clutch (clutch disc, pressure plate and in some extent the flywheel.). When this happens on new cars it has to be where the clutch wasn't installed correctly or their is a lubricant contamination on the pressure plate or the clutch disc itself. If it isn't contamination the only thing I may consider is the motor mounts. If those are OK its a clutch issue. I drove a brand new 2009 Shelby GT500 and the car had it pretty bad. A lot of the time on a new car the chatter will somewhat diminish. When I bought a new 01 M3 at the time I test drove another car that maybe I would switch into..the clutch chattered so bad I passed. Has it done it since new?
I would switch out the clutch as this isn't a warrantable item anyway and get a new flywheel not one resurfaced and see how it goes. This would be a great time to do a LWFW.

Pics
Two pics, one from today's visit to the dealership and one before the engine meltdown (and no, I don't drive around with the spoiler up 
, it was done for the picture). I did not realize that the entire bumper and side covers needed to be removed; I guess it's to clear the exhaust? I asked to see my old engine but it was gone already. I mentioned the clutch again and my SA assured me he would further investigate a potential cause other than the usual suspects so to speak...

Hey 500, thought I would get you an update, my engine arrived yesterday....They are booking me in week after next. I guess they have x2 other engine replacements to do on cars that aren't driveable and asked me if I could wait an extra week....I am not overly inconvenienced so I said ok, would like to see another p-car driver get on the road as I am still enjoying mine.

How come the dealership did not have to tear down your engine like they were instructed to do on mine? Apparently internal inspection is part of standard Porsche protocol prior to replacing an engine.

Wonder how this can vary when it comes to replacing an engine; can anyone with specific knowledge chime in here?

The wider 305's are standard on C4S's (they have 8.5 inch rims), the C2S's (even with the turbo wheel option) like mine have 295's with 8 inch rims in the rear.

Correct, thanks for catching that...but the C4S fronts are also 8.5 just like the turbo, or so I thought?
