Tramlining: on my '17 R (which were worse for tramlining than the '20s, which got a revised steering knuckle), a set of PSS virtually eliminated tramlining, even with a track-friendly alignment.
Street-friendly tires: PSS or PS4S, or Continental ExtremeContact are all good. 325s will fit in the rear, but I actually went 305s all around on my R. The rears were slightly stretched but they were nearly as wide as the stock 315 Cup 2 tires, because of the more square sidewall profile of the street tire. I think a lightly stretched 305 is better in the back than a 325 with some sidewall bulge.
Seats: can't help you there; Recaros for me
Rebound: I think the non-R is a little under-sprung, with damping to match. Sport mode is probably best for most street use. No experience with the DSC controller.

I run the 325-30-19 rear on my R. No rubbing at all. I think there are suppose to be a few more size options coming... At some point.....

I would still buy a 2019/2020 GT350 over an older 2006-2012 Porsche GT3 today (a 997.1 and 997.2).
It is no doubt that you will pay almost 50% more to get into a Porsche GT3. I would also mention that the Porsche parts (they are old cars) are very expensive to service. If you need them to service your old 997 GT3, the service department will hang you out. Big Time.
The Porsche computer will not allow you to reset the maintenance schedule. You can re-rest your your Ford service in 20 seconds.
I own both so not exaggerating my post.

I'm in a visual love affair with 997 GT3s...just love looking at them. Price though...I bought an R for the second time. I just cant justify $125k+ for a 10 year old car that in turn will be somewhat expensive to maintain. Everyone talks about how GT cars hold their value and it's true to a degree....until you drive them. You cant put 60k miles on a 997 GT3 and then get your money back out, no way - the reason is that there are tons of people NOT driving them who just resell cars every few years. The only way I could consider it is if I invested in some porsche tools and did my own work on the car...which I can do but I already have a 964 project waiting...so that's enough of a money pit.I would still buy a 2019/2020 GT350 over an older 2006-2012 Porsche GT3 today (a 997.1 and 997.2).

All,
A delayed entry after another trip through the hills. Had a revelation last weekend; as long as the pavement isn't complete garbage, Track Mode is the ticket. Used it for the first time. Big improvement in body control, bob and weave, head toss, whatever term you like. It was very, very good, and a real competitor to the GT3. I loved it. My wife wasn't with me, so I'll repeat the process with her sometime to get her opinion. From my seat, the car was more planted and more fun to throw around. Looking forward to another run when the latest arctic blast moves on.
Also decided this one will be a permanent addition to the fleet and sprung for an extended warranty through Anderson and Koch Ford. Now I just need another garage stall...

I also had 5 previous Porsche cars including this 1973 Porsche 911 2.7 RS replica (air-cooled).
#1 When I roll into a Ford service bay with a new GT350, they figure I know my car.
#2 When I drive into my Porsche dealer, the poorly trained idiots assume that I have no clue about cars. These idiots are trained to upsell you for stuff that is really not needed.
Porsche North America and the Porsche dealers think we are stupid. They hire a bunch of idiots that are only trained in adding stuff on the bill (most have 6 months of experience). I say no.
I have one of each car:

I don't know about Porsche because I never bought one, but so far I have had the same experience with my GT350.I also had 5 previous Porsche cars including this 1973 Porsche 911 2.7 RS replica (air-cooled).

Took both cars to Hallett, OK for a track day. Only 4 or 5 cars on track at a time, and we were in flights based on lap time, so very little interaction with other cars. You could lap for twenty minutes and only interact with one or two cars. Lots of fun (and thanks to Perfection Plus in Little Rock for arranging the day). I'm a decent but not great driver, so I asked someone with racing experience to drive both cars for a fairer comparison at the limit. All times are on the same track with the same driver and same conditions. The GT3 has lap times on a used set of Cup 2 tires (about 9,000 miles but plenty of tread) and brand new PS4S tires. The Shelby was on the OEM Cup 2 tires with 3,000 miles. For those of you really into these things, it was roughly 60 degrees and sunny at the track.
GT3 w/ Michelin Cup 2 - 1:26.1
GT3 w/ Michelin PS4S - 1:26.7
Shelby w/ Michelin Cup 2 - 1:28.7
So, 2.6 seconds between the two cars on equivalent tires.
In case you're wondering, the other driver was 1 second faster than me in the Shelby (I ran 1:29.7) and 2.5 seconds faster than me in the GT3 on PS4S (I ran 1:29.2). (I ran 1:29.4 on Cup 2's, so go figure...) I asked him to drive because I was pretty sure the difference between the two cars was greater then the 0.5 seconds I experienced, and therefore the limiting factor was the driver (me), not the cars.
His commentary mirrors my own though. The GT350 was loose until the Cup 2's got warm (which took more than 1 warmup lap). After that, the car was balanced, easy to coax through a corner and has simply tremendous brakes. It was very forgiving when I overdrove some approaches and lifted mid-corner. In those cases the nose just tucked in and pulled the car around. No lift off oversteer or other bad behavior.
Lastly, I used Auto-Blip when driving. It's not perfect like the rev-match in the GT3, but it definitely helped. He turned it off and used 'heel and toe'. I need more practice, and lessons...

PS4Ss are very wide tires (even more than PSSs). If you look up the tread width for 295/30 and 305/30 it is identical to the 305/30 and 315/30 respectively Cup2s. I am seriously considering getting a set of PS4Ss in that spec (295/30 and 305/30) and try it. For the street I have had it with the Cup2s.
