Nankank CR-1 vs. A052?

I'm about to buy tires for track days and time trials. Tenths matter! Was going to get A052s but came across some info that suggests the Nankang CR-1 could be quite a bit quicker (see post #2):

Anybody here tried these?

The A052 is faster.

From reading seems like they're close to each other but cr1 may get a few more heat cycles.

I ran a052s last year and am trying Cr1s this year. A few more heat cycles is a good tradeoff if it's pretty close speedwise, in my mind.

Unfortunately not my data to share, but in a controlled environment, the A052 is consistently faster by a small margin.

What type of track work?

Sprints and Laps are two very different situations.

3-lap time trials, usually there's a full warm-up lap, sometimes half-lap warmup.
But I'd also like to be able to pound around for 15-20-minute sessions...

Ah. I can't help you there. I also see now that the 52s are not the successor to the AO50s like I thought so I have nothing to offer really.

Either of those tires are not durable enough for any longevity questions. An A052 set I had with some Solo Nats runs on them lasted ~4 hours before total the tire had no tread left.

If you want a fast 200tw tire, it will not be durable.

Both are not suitable for full wet conditions, PS4S or ECS
