cups - Page 4

Agree with Mike and i've said it before. Cup2s are not a patch on old cups or anywhere near the times of the Dunlops or Pirellis.

Cup2s come on quick, but fall off a cliff even faster. Better road tyre than the others but for outright laptimes you need to look elsewhere.

I also drive the car hard.

No chance I'd sell them at any price with current situation.

So let's go with the assumption for now that different platforms perform quite differently with the same tyre.

Last week I tried the Yoko AD08R on a 800kg XBow at Spa. They were really good. Faster than an older set of mixed R888 and R888R. Also much cheaper than the other usual suspects. I see they are available in CSL sizes. Anyone tried these?

(Incidentally the Germans are reporting R888R failures on the KTM - torn sidewalls - hence I didn't use those. Perhaps the higher G loadings on the XBow put more pressure on the tyres in the corners?)

Another point on tyres. Majority of us non professional drivers are always on a learning curve. So comparing views of cup 1 from two years ago to a modern tyre today is risking the rose tinted affect. I'm certainly many seconds quicker today and would be putting many times more demand on my tyres today than two years ago.

fair point. How much is a set of AD08R in CSL sizes and from where?

Search for Ben Patey on Facebook - he is the main man for AD08s (see my thread about the tyres for more info)

In principle I agree with you. Unless you max out the potential of a setup, it's pointless to compare as you get better.

I am going to compare the cup 1 with the cup 2 tyre in a track that I have over 1400 laps with car (~1000 with the CSL) and 150 with bike.
The only option for me to go faster in this track is if I cut through the grass and skip parts of the track

This is how fast I drive the CSL there.
I have the consistency too; I can drive lap after lap within 200ms.

Going in this track with the cup 2s is what I am going to do and I will compare the corner speeds between the 2 tyres.
I hope this makes sense.

Superb, that should finally confirm what most of us have been saying

Great. I'll save you the write up.

They're shit.
