Ass Jessrayo describes with tires you have to compromise. You can't get all in one.

The PSS might be an overall better summer street tire than the GY's but I still doubt that the PSS will be better on the road course .
First they have a softer sidewall and second based on feedbacks from the Porsche community they tend to overheat and become greasy quickly ( i have personally experienced it also in a GT2 on the ring).

Before I jump on the PSS bandwagon I would like to see some data which supports the statements about them being faster than the GY's.
Use what you like.

If you use the Goodyears as a track tire, then I am speechless.
It's a street tire, not a track tire.

Don't jump on the PSS bandwagon. But remember that GM did on the Corvette C7. Like you said, "there is a reason GM choose them."
