I've been running the Yok A052s on my Cayman this year. Grip is great! Including in the rain (at least when they're new) But life is very short... I only got 4 track days (one of those in the wet!) out of them before the tread started separating on the fronts. I've only run clockwise circuits and at the end of the last one I saw that the outside tread of the left (outside) front was delaminating. At first I thought maybe -2.9 isn't enough front camber but then discovered that the INSIDE of the front right tire tread was also delaminating! I had to take slow roads home as I could hear and feel the fronts trying to come apart above about 55mph

Meanwhile I'm now dailying the BRZ on RE71Rs that have 10 track days (2 wet) on them. They're slicks now, but not corded or delaminated!

Conclusion: A052s are quick, but short-lived and fragile
