Very good point, and fortunately (or unfortunately) for me both cars were/are equipped with very similarly used OEM Pirelli Tires. I am with you on placebo, and am extremely **** about such details. Have tried to factor in all of that
before sharing such a (what I consider to be) strong and definitive statement. Thanks in part to cover-19, I had plenty of time to drive, evaluate and come to this conclusion.
Both were CPO and my OCD required both of them to have a Post-purchase inspection at local dealer. Neither car had/has any aftermarket parts.
On paper, other than slightly wider track of GTS +and slightly different/more pronounced sound, there should be almost no difference in drive or feel... YET, the GTS has loads more steering feel and feedback, and seems to have endless rear end stability..where the C2S used to at least begin to give rear end warnings on same exact piece of tarmac, the GTS just stays planted. I am convinced that Porsche, between the years 2012 and 2015 upgraded Steering software and made geometry changes to the GTS without advertising it. Either that or there have always been an undisclosed difference in suspension setup between C2S (with SPASM) and GTS. To be fair Porsche has always advertised C2S cars with S-PASM as having the same hardware, the exact same PASM suspension can easily be "set up" differently without having to disclose changes. All I know is that the difference is beyond noticeable and impossible to ignore.

I'm not trying to challenge what you felt at all. It's always good to hear experiences!

The 12 and 13 dont have rev match (which I prefer). There were cov failures on some cars but these are just cheap plastic valves. The early cars have not surfaced any inherent specific flaws. They all have a design flaw on the door panels but a dude in florida named pedro can fix them permanently for reasonable. 3.8 is the one to have.
