I just got a pair and they are great. If you don't drive in wet conditions or in temps 45 degrees or below, I would get a set.

NGNG, I thought the same thing also that the N spec is just a tax on the tire to get a Porsche designation. However, after getting my first set of non N spec, then a set of N specs and seeing the physical differences, I could only wonder if there were also some other differences that couldn't been seen with the naked eye. That sent me down a rabbit hole and one article that I read got me and has convinced me that the N Spec, M0 Spec and any other spec tire is actually a different tire than their non designated counterpart.

i'm sure there are some differences, but i suspect most people won't come close to feeling those differences. and if you are pushing the limits, a street N rated tire isn't going to compare to a dedicated performance tire

@RAudi Driver I just checked again and it was for a 991 GT3 RS and not a 997. Doh! At any rate, I'm not too worried about it. Good to know for next time though! I'd love to try both N spec and non-N and see if theres an actual difference in performance.

No worries, I only got my N spec for the look of no rim protection bead. Didn't really know about any other performance difference between them when I was looking for tires.
