Mid-year update on my A052 choice. Purchase back in March/April and I've done 13 autocross events with 88 total runs. 2017 BRZ, 225/45/17, OEM allowed camber bolts with 1.3* camber in front, zero toe all around.

The tires are heavily worn on the outsides to the point you can barely see the tread. Not really surprising. They're due to be flipped to get through 12 events (~78 runs), although I'm not sure they'll make it. Beyond the outer edges, the middle is right at the wear bars. RE-71Rs, in 3 sets, I never had to flip, and I took two sets to 190-200 runs. Most surprising is on one tire the outside is so worn or heat cycled it's actually hard or 'burned'. It's weird and only on the edge.

Overall, I'm on the fence with the Yoks. Like others that have tried them in our region the consensus is "they're not he right tire for the car" when referring to street class, low camber cars. They've laid down some good times here and there. Other time like now in June/July, they're overheated and my final 3 runs are greasy - even with spraying them between runs.

I think that the RT660's might be better for an all around tire that's going to get you through 20+ events, lower camber car, and deal with temps from 50-90 degrees. I'll probably choose these next year and see how they compare.

Now, if you're in STX with coilovers and -4* camber, I do think the Yoks would be the better choice. Might have to sacrifice a bit on super hot days still though.
