Nankang CRS-V2 on 992 GT3
#16
I went for the CR-S over the AR-1 because the CR-S is supposed to be faster than the AR-1 (as per Nankang's website). From my understanding, the CR-S is more of a time attack tire - it has a softer compound and the same stiff sidewall as AR-1. According to Nankang, they say the CR-S is better in almost every regard to the AR-1; it's softer, more consistent, better wet performance, more consistent, less road noise, etc. I guess they just left a lot on the table with AR-1 and so it was easy to improve on it for the next tire. The biggest thing for me though was the greater tire life. CR-S comes delivered at 7/32 instead of 6/32 like the AR-1 so not only is there more room to shave the CR-S down and make it faster but it also should last longer without shaving. Although, I don't know why it's labeled a 200tw when the CR-S and AR-1 probably do last similarly as long, plus the CR-S is softer than AR-1. I guess they must have made a bunch of technological improvements to make what they call a 200tw faster than their 100tw offering. Hopefully they'll start offering a AR-1 V2 soon that has the updated compound of the CR-S so that the AR-1 becomes a faster tire than CR-S, as per their TW ratings.

I wonder if the OEM sizes would be better or worse than the 991 RS sizes for 992 GT3?
Technically, the 315 is supposed to be used on nothing wider than 11.5” wheels (GT3 has 12”). I posted specs above, but seems like their tread width is wider than N-Rated, so probably fits fine.

Not sure if you can tell, but the Nankangs (first pic) are more flush with the edge of the wheel than the Goodyears (second pic) Another way you can tell is the edge of the Goodyear is somewhat curved because of the way it’s stretched over the wheel. The Nankang doesn’t have this characteristic because it’s a better fit and lays flatter on the wheel.

I mean the 315 OE Goodyears will probably fit similarly to the 315 Nankangs. The Nankangs will fit a litter snugger and have taller sidewalls than the OE Goodyear. Wish I had a picture for you but the 315 Nankang will just be somewhere between the two pictures I posted

Thanks! I have -2.5° all around. You think the clearance is tight enough for you that the 265’s might rub in front with a bit less camber?
#27
I doubt it. -2.5 is a good amount of camber, especially if you're running stock ride height. I have no rubbing on the street thus far with my lowered height. I think there is plenty of clearance.

It also looks like they make OEM sizes for the 992 GT3 in CR-S:

Interesting that TireRack categorizes these Nankangs as "extreme performance summer," while all three GT3 OEM tires (Michelin, Pirelli, Goodyear) are listed as "streetable track and competition." This would suggest that the Nankangs are less "extreme" or less track-focused than the OEM tires, and yet postings here and elsewhere suggest that the Nankangs are faster and more track-focused than the SportCup2s, PZero Corsas, etc. Interested to hear more thoughts on these vs the OEM tires in a track setting.
I think use categories and TW rating are not always to be taken too seriously.

Yes, I think the categories are not very scientifically defined. I remember the old Bridgestone RE-71R was also a Summer Max tire, but faster than Cup2 on some Porsche GT cars. And these Nankangs that are 200 treadwear apparently are faster than their 100 treadwear tire (AR-1).
