It seems clear to me that the Blackwing-spec PS4Ss lose a fair amount of grip well before the tread wears out. I have 16.5k on mine, rears will probably make it to 20k before the wear bars and fronts 25-30k, but ever since 10-12k I've had much less grip esp. in the rear. I used to hook up pretty well in 2nd (straight, decent temps, and on a good surface) and even in 1st if all the conditions were right, but lately it's a much different story. I've even waited until nice warm temps and went on a spirited drive to get the tires "Warm" according to the cluster, but it's still pretty different from when they were fresher.
Anyone else have this experience? No track miles on this set. I think it's due to the Cup 2 compound that's put into part of the Blackwing-spec version (I read somewhere that it's about 60% of the tread, but not sure if that's accurate). I will say I'm impressed by the treadwear at least. 20k out of rears is downright amazing with all the torque and weight. In the past I've gotten 9k out of rears on a 2011 M3 and just replaced my Lotus Elise's rears at 4k (both ~200 treadwear).
