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:

Po polsku będę pisał. Google przetłumaczy. Jeździłem na cup2 z tyłu potem zmieniłem na zzr z tyłu. Zzr jest dużo fajniejsza opona na tył. Bardziej stabilna, łatwiej wyczuć początek uślizgu i nad nim zapanować. Zzr ma więcej też przyczepności. cup2 się na tyle nie przegrzewa tak samo jak zzr. Dodam tylko że mam katy ponad -3 stopnie i z przodu i z tyłu. Dodam tylko że miałem na tyle 225/45r17 a64. Cup2 za to lżejszy i bardziej komfortowy i przyjemniejszy na codzien. Nie męczy tak twardością jak zzr. No i cena świetna. 2/3 ceny zzr. Ale jak mówię czasy plus 1-2s na 2 minuty do zzr. Ja bym ich jednak więcej nie kupił. Zzr na tyle są lepsze. A na przód chyba pójdę w a052 215/40r17. Podobno ma miękki bok i super trzyma na suchym i to od strzała co na codzien na ulicy zapewni nie blokowanie przednich kół podczas hamowania na zimnej ulicy czy w deszczu i dzięki miękkim bokom nie zmęczy w odczuciu na kierownicy ( nie będą drgania przechodzić na kierownicę) a na torze też da dobre czasy. Miałem na przodzie 195/50r16 zzr a24 to koła się odrywały od asfaltu, za twarde opony na przód a po drugie spaliłem je szybko. A64 jest dużo lepsza mieszanka i od startu trzyma podobnie ale wytrzymuje dużo większe temperatury. Żeby oponę na przodzie spalić? No cóż a24 się spaliła. Nawet w r888 tego mi się nie udało zrobić na przodzie. No cóż. Teraz mam na przodzie kumho v70a k91 czyli twarda 215/40r17 to trzymają po nagrzaniu świetnie ale jak są zimne są bardzo sztywne i twarde no i na deszczu wręcz tragiczne i niebezpieczne.
Co do zzr a64 i cup2 na deszczu to chyba bardzo podobnie się zachowują. Avon 7mm głębokości a cup2 5,5mm ale na deszczu na mokrej jezdni całkiem podobnie. Da się z nimi żyć.
Więc jakbym ja miał wybierać między zzr a64 a cup2 wybrałbym zzr na tył i cup 2 na przód.

new tracks are generally faster anyway, look at Croft lap times, 1'34/35 before the resurfacing and now cars are 1-2 seconds faster on the same tyres. 

 

i ran ZZR's on a couple of trackdays and found they took quite a while to warm up, but when they did they kinda stayed good and never went off in the 20 or so mins i was on track, but the ultimate grip level was lower than that of the 888's i had previously, the problem with the 888's were they warmed up fast then started to slow down the hotter they got.
