Sorry, I missed this in your original reply but just saw it with the recent bump of this thread.
Here are my alignment #s including corner balance. Tire wear is actually very good and with the suspension upgrades and everything being locked into place, haven't needed to change anything since I originally had this done about 14,000 miles ago.
The car was standard cabrio with PASM suspension. So let’s start from basics. For you that have the basics you can skip this part. (Following is for 2WD with manual gearbox. 4WD and PDK have different settings)
997GTSsweden great thread, appreciate that you covered all this with such detail. Also, it is a relief to find information on a GTS Cab.
I recently got a MY11 GTS Cab 2WD -PDK. The car came with H&R springs. I would like to raise it a little - perhaps switching to Eibachs or M030 springs. For M030, might you know the OE part #'s for springs I would need? I note you mentioned PDK settings differ from the manual model.
From one Karl to another, greetings from the Northwest. Thanks for the link and lists.
The factory doesn't seem to list an OE M030 option for the cabriolet. The same is echoed by my long time trusty parts manager at our local Porsche dealer.
(note - rear springs the same for cab and coupe, in both 475 and 030)
Stumbling on this thread regarding a similar model cabriolet, I feel closer to some conclusive advice. Well, except for the OP's remark that what worked for him is specifically for the 6sp. Maybe the coupe parts work on the cab, and 6sp/PDK use the same spring rates, etc...
nwGTS offered the initial advice that I could look into switching to either Eibach or SPASM (which I am sure is M030). I am leaning toward SPASM. Would be great to have confirmed part numbers for what will fit my cab.

The convertibles was never delivered from factory with M030 as an option unfortunately so you have to use the coupe parts
Ok. That makes sense, since aftermarket (ie. H&R, Eibach) seem to use the same for coupe and cab.
According to the "parts list" GTS (coupe) PASM
Front spring: 997 343 531 495 04 (030)
Rear spring: 997 333 531 865 04
The rear spring is the same for PASM and SPASM. Does this sound correct?
May it be better I order using 996 numbers? According to Elephant Racing, the M030 "stock equivalent" springs:
Front: 996 343 531 125 04
Rear: 996 333 531 625 04
Are these what you used, on your 6sp cab? Perhaps I use the same parts and setup, even if my cab is PDK, maybe?
Thank you for the advice. Awesome to read how well your cabriolet is handling.
I used following springs that is M030 in Europe for C2 MY 2009-2012 that I ordered ;
99734353149504 front silver/silver marking
99733353188504 rear silver/silver/yellow marking (should be 99733353173504 but replaced in PET by 88)
US M030 is a little bit higher ride height than RoW rideheight. Elephant provides a mix of US and Euro spec and it is still for 996. I would go for the ones i ordered than it covers MY2009- for 997.

997GTSsweden - Thanks for confirming these parts are what you used on your Cabriolet. Sorry, I see you already posted these part #'s earlier.
I realize your original post (#1) was posted nearly 4 years ago. Would you kindly repost your pictures? For some reason, the images no longer open or enlarge. If easier, please feel free to private message me (just hope I can receive PM's).

But certainly from the 997.2 (and maybe the 997.1), US cars have the same springs as RoW spec cars.
This means US M030 springs for a 997.2 are the same as what you listed...
wjk_glynn - I've read the same, in a few places. I changed over to RoW spec on my 996. I liked it a lot.

997GTSsweden - please disregard my request. I trust it is not so convenient to gather and repost old pictures.
I remain curious, if you are using OE RS Spyder wheels - center lock and original offsets?
Are all your suspension mods and alignment settings the same as coupe?
