If you have used 888R? I would say grip of 888R is slightly better than ZZR.

All other attributes I would say ZZR is better : turn in/sidewall stiffness, endurance and wear rate.

 

Probably not much good...you now need someone to compare 888R against A052!

I had zzr on front and have v70a on front now. Zzr is to stiff on front. On rear sidewall stiffness zzr is ok.
I have read many very positive reviews about a052 but I would like to make sure that they are doing good in vx220.

When I had ZZR’s I found they went off (hard) quickly with heat cycling so while they had good tread the grip dropped off after the first couple of track days.

I race my Caterham on AO48’s and they keep putting in the lap times right down to the canvas (although warm up time increases but that’s not a problem for track days).

If the price was similar I’d go for the Yoko’s.

If I recall correctly ZZRs not "legal" for road anymore so I switched to ZZS. Did not feel much difference in the dry, but in the wet they are night and day and as I can be driving 250-400 miles each way to a track day I think the ZZS is a much better option to ZZR unless your car is track only mostly.

I can confirm now that the A052s are faster than the R888Rs. Our local track washed away in a flash flood earlier this summer and they luckily rebuilt quickly .
Got out on track for the first time since running with the R888Rs last season, which my best time posted was 1:07.5.

I knocked a full second off that time almost immediately, 3 laps into the first session, and followed it up with multipl 1:06's. Then knocked another full second later that day as I settled in.
The alignment is worse than it was too, I have to keep the front end of the car higher than it should be to clear the front tires with the very aggressive offset that the wheels have. So I think there's another 1.5 seconds to be had likely too.

The G Meter on my fastest lap with the R888Rs was 1.1 sustained and barely touched 1.2G in one corner versus the 1:05 lap where it's 1.2-1.3 sustained and touched 1.4G

Fastest Lap with the A052s:
