So given all the tires that are out in the marketplace right now (Nov. 2017), which would you put on your GT for street use? I’m about due and would definitely consider not purchasing another set of Goodyears.

The answer is still the Bridgestones.

Just put new rears on my car (Potenzas). I've always used tire rack, but this time I bought from Simpletire - $60 less per tire than the other guys, free delivery, and date coded 42-16. They arrived the day after I ordered, I'm sold on this outfit!

Just ordered a set of new Bridgestone rears from them. Mine are down to the wear bars after my 3600 mile walkabout to Wyoming and Utah. Thanks for the link!

After researching the optimal sizes on the Bridgestone Potenzas (RE050A), it looks like I’ll be doing the following setup on the optional BBS factory wheels:

Fronts: 265/40/18 - N1 Porsche

Rears: 345/35/19 - Scuderia

From what I’ve read, there doesn’t seem to be any downsides to this setup.

Who else has this setup, and what are your thoughts compared to the stock tires?

I thought that was THE combination to have.

They have been excellent tires. Quiet, handle well in all weather and dependable. I've got 20K on them total. I think running them at 28 psi will stop them from wearing out in the middle. Have your alignment checked beforehand.

I'm on my second set of this pair. I used them for street, long distance highway (to the Left Coast and Rally 12, then back to the Right Coast this summer), and on the track at UMC at Rally 12. Great all-around tire for these cars. I've driven them back-to-back with the Goodyears. They aren't particularly noisy--about the same as or less than the Goodyears. I run 32 Psi and don't have any problem with them wearing out in the middle, however, the front and rear tires will wear out on the inner edges with the stock camber settings.

I moved the front and rear camber settings to almost zero camber to improve tire wear and life (actually about -1/4 degree), and on the street that works great. On the track, the tire will slide just a bit more easily, but it also slides more predictably, IMO. Unless you are actually RACING, you I doubt you'll notice the difference, and you'll get 5000 more miles out of your tires before they are down to the wear bars. Fair trade-off for me.

Better straight line traction also.

Has anyone ran the Toyo Proxies R888R in size 265/35/18 front and 345/30/19 rear?
If so how do you have photos and how did it change ride height or look?
My car is pushing over 900hp so i need meat and traction.

A 345/30 size tire is going to be almost 1.5" smaller in diameter than the 345/35. On radius ~.75. So, car will sit about .75" lower and your wheel well gap will be about .75" larger.

A different circumference will alter the handling characteristics & speedo/odo reading.

Yes, and the ABS module may be very unhappy as well.
