Check TireRack, they have stock of the MPSC.
Although a few other tire stores said they where not available anymore.
I've ordered a new set.

Looking forward to how they perform on the track in a few weeks.

When you reach the casing rubber, you will have almost no grip and slide everywhere, unlike NT01s or RA1s, which basically become like slicks when the thread is worn away. I'm no tire engineer, but if you look at these pair of 305-30-19 R888s used on a GT3, you can see some type longitudinal mold pattern in the rubber as it wears down which looks something like bonding ribs between the casing and the thread. It looks like there's still thread, and it's just a bit past the wear bars, but really, there's no grip. You think you bought 6/32s of thread, but really are probably only getting 3 or 4/32s. If running 2* or more rear camber, and depending on how much straight line or street driving you do, you'll wear away the inner 1" of the thread pretty quick and slide around on that too, not giving the tire a chance to stand up and grip when cornering. In a ~80 second autocross lap, the difference between these and a proper set of tires, these were over 10 seconds slower, back end drifting, shuffle steering in opposite lock around turns.
Empirically speaking, I have to agree with your comments. The 888s don't perform well after a while even if visually they seem ok.
It is rather strange that Toyo marketed this tire as an improvement.
In addition I have an email from the Toyo UK, where they say that the compound of the 888 is similar to the compound found in their older line. Perhaps you are right and the newer / revised construction method of the 888s has this disadvantage.

That is it and we can't do anything about it.. 18" are dead.

What is the difference between the N0, N1, N2? What was updated? I see all three on tire rack.

OK here is my understanding (which might be wrong in parts):

N0 - 997.1 MPSC compound
N1 - 997.2 MPSC compound
N2 - GT2RS 325/30-19 rears (only, there is no N2 front AFIAK)

Thanks.

Yeah Tire Rack only shows the N2 in sizing for the rears.

And they list the N0 as a close-out.

All the rep knew was first came N0, then N1, and now N2. I shall do more Googling

Can you mix N1 with N0, N1, or N2, or whatever combo?

GT2RS mixes N1 fronts with N2 rears ... .2's are all N1 ... N1 supercedes N0 for .1 cars I believe.

I think the N2 rear for the 2RS may be a stiffer tyre ... check the N1 vs N2 wear ratings ...

I believe some 3.8RS RLers are running the N2 rears with success...

dont know what the 4.0 comes with on the back ... maybe someone can comment?

I'm still trying to find those. Almost as elusive as the RA1's. I would love a set for my stock 19's.

they are likely next to the "hen's teeth" and "unobtainium" since they are only a GT2RS fitment I cannot imagine there is much if any stock given the low numbers of cars in the US ...

I'd be tempting to ping Damon @ Tirerack as they are maybe special order ...

Also, given the increased power on the 2RS ... I'd wonder if the harder compound might result in less grip on a 3/RS???

dont forget to go 245 up front also ...

Hi guys:

Here in good ole Deutschland the N1 and N2 are exactly the same price - at least from the tire shop who is doing the race service for the Porsche Sports Cup in Germany. Did not yet try the N2 but will investigate some more and see if I can find out the differences (advantages/disadvantages) for a GT3RS2
BTW: no problem whatsoever to get the tires here

The figure to the right is the price in Euro with German sales tax (a whopping 19 %)

Best regards

Peter

Your prices are cheaper than in the US. Wondering how much it costs to ship them over.

Thanks for the update on that. I don't need to read autoweek or that stuff. Just come here and it's all good

Hi there:

Since they are big and heavy it will be expensive to ship. Also not sure if you could pack a full set of 2f + 2r together. Do you need to pa duty on these when they come into the US? Maybe a container load full of tires would make sense but than you surely would need to pay tax and you can not do this on a "private basis" anymore.

It actually is the other way round the same. Some real nice parts (and cars) are way cheaper (better say not as expensive) in the US. But with shipping, duty and German sales tax on top you lose all the advantages and more
