I am going to try this next. The real issue is Treadwear. TrofeoR is 80. Whereas Cup 2 is 180 and PS4S is 360. So from that you can see that PS4S has twice as much tread wear as Cup 2. And Cup2 just over twice as much tread wear as TrofeoR. Less tread depth = less tread squirm, better feel, better handling. Less miles.

(1) . They are terrible in the wet
(2) . They have a UTQG rating of 60
(3) . Better than MPSC2N1 in dry - but not by much

I'd be rather hesitant to trust those Pirellis in the wet because of the tread pattern and lack of water displacement grooves. I ended up having to make room in the trailer for another car while we were on the road and had to drive the GTS home 500 miles from Road Atlanta so I unmounted them and went back to the stock Michelins; I was too nervous about a wet ride home. Given how soft they are I didn't want to put 500 highway miles on them either or pick up a nail somewhere.
The ride home was nice and comfortable. With the full monoball suspension there's a tiny bit more road noise but it wasn't harsh by any means. I'm rather happy about it because I still want this to be something you guys can have as a track weapon that can be driven to/from the track. With the PSE off and PASM off, it's quiet and comfy.
I met a really nice guy at the gas station who follows this thread and came up to say hi. If you're following, please send me your contact info. I wanted to spend more time chit chatting about the car but I was in the middle of changing Cobb maps and I didn't wanna move til it was done flashing. I didn't have the battery charger with me so I was doing it at the gas station and when you install/uninstall it takes a few minutes so I was scared to get out and kick the OBD cord! Thanks for saying hello and I hope to see you at the Roar in January.
As for the performance on the trip home, the car gets 29mpg on a 500 mile drive that was half back roads and half highway. It's a great machine and probably the most well rounded Porsche I've ever had the pleasure of owning!

I removed my wheels today and the Caliper size are as follows for base Carrera and T:
Font: 34mm thick, 330 mm Dia., hat offset is 39 or 40 mm. Sorry about not being more accurate but this should get you too another Porsche standard size. Other Porsche rotors in size 330 x34 mm have hat offset of 35 mm.
Rear: 30mm thick, 330mm dia., hat offset is 51mm. This is the same as rear of the 997 turbo and many other sizes and same offset as 996 GT3. Brembo list hat offset as 47 mm for the GT3
Can anybody verify hat offset for the base model ?
also, the T comes with really nice and big brake cooling ducts and channels. Look efficient.

Too right, the MPSC2 N1 aren't that great either - just did a hill climb, first half of the day it was wet. Lots of fun but slow and often sideways. PM, dry surface boom off to the races with tons of grip.
