If you go to Hoosiertire.com they have the new compounds and sizes posted. Looks like a close size for the 997 GT-3 that will fit on the 19 X 12 rears.

hmmm that's interesting...

Dr. Car

The 265/35 and 325/30 are a possible fit for the Carrera. They could be squeezed on the OEM wheels by a determined tire mounter, and would fit well on the optional 19x8.5 and 19x11.5 rims. The question is, will there be rubbing and is there a downside to the slight gearing change and 9-10mm higher ride height with those wider, taller tires?

I'd be concerned that on a GT3, the combo of 235/35 and 325/30 would require some aggressive and somewhat self-defeating sway bar adjustments to avoid understeer, namely, more rear bar. I'd try to match the 325 with a 265 on the front.
