Need some advice on tires for my RS?
I'm not new to tracking/ racing but new to the Porsche side of it. I have a 2010 GT3 RS and have taken it out twice on the track. Still learning the car, but need some advice on tires. So far I have GMG center section, GMG roll bar, Harnesses, BMC air filter, stainless brake lines, SRF fluid, track alignment. I have run it only on the stock tires but just ordered a set of 18" BBS wheels. What size/brand tires you you guys recommend? I did a search and lots of different opinions.
Thanks,
SW

I think you need to clean your garage. 
Pirelli Trofeo R's have been getting some good reviews. Some still use the cups. Do you want a combination street tire or a track only tire? Some people swear by hoosiers R comps. just depends on what you want. I'm sure others with more experience will chime in.

I put an open-to-public for editing google spreadsheet out there to compile the options for tires and recommended alignments.

It's missing the Tofeos....

I would suggest running a stock tire or R compound until you get used to the car. You want a tire that has lower grip so you learn the dynamics of a Porsche at a lower limit. Slicks will give you more grip, but less warning. So if you're experience is limited in the Porsche, it will be much harder to control and stay safe once you reach the limit. Don't waste more $$ on mods. You've got a solid set up... good call on safety. Now get used to driving the beast and pushing yourself at your own pace. Your RS will be harder to drive at the limit vs. your Ferrari/Vetter, but will be more rewarding once you tame the beast.... some even prefer the driving dynamics of the rear-engine vs. mid-engine.... there are benefits once you know how to work it.

If they produce NT01 rears for our car, that will be the best DE tire bar none. Excellent grip, lasts forever, and doesn't need to be shaved. 1 heat cycle and your good to go....
Good advice above on running Super Sports or Trofeos. GT3 is a different animal to drive, so are good audible tire will help with learning. DeputyDog runs SS on certain track events, and he speaks very highly of it. Hoosiers will give you zero warning if they lose grip.
About setup, best to run Hoosiers at 30-32 psi HOT. At least that's what I remember people saying. For a good R compound, 33-36 is a good sweet spot. It really depends on the specific tire and how stiff the sidewalls are. For alignment, again matters greatly what tire you run. Hoosiers require more agressive camber infront. Say -3.5 to -3.0. Rear is good at -2.0. For a R compound, -2.2 to -2.5 is the average. Rear is -1.7. Toe should be 0 degrees front, -2mm each side rear.
I'm throwing numbers that I have played with, and also what other members have run. Really, it depends on how you drive, and what feels best for you....

R1's Are not that great IMO.. I feel Hoosier R6 are better.
I have limited experience on the new R1's though...
Nice Garage BTW!!

I use Hoosiers they stick like glue but if you are prone to spins you will flat spot them.

SW You'll be fine on R6s, you have more than enough seat time in your other cars to have the "feel" to make proper adjustments.
Get some RSS Toe Links for the rear to help keep things in alignment. If you're going to track it a bunch and want to go all out (like you usually do) check out some of their control arms and other suspension bits that are a great addition if you're going to be on slicks.
