This thread has convinced me to go with PSS in the spring, was deciding between this and Direzza Star Spec. I can't wait for winter to be over, though it hasn't quite started yet.

Noise is somewhat increased over rough aggregate roads and sharp inputs, but I mainly noticed that after installing the monoballs. The GC plates likely have less and stiffer rubber compared to the stock mount. Stress issues? No, none.

Unless you are going to be timed against a clock on dry pavement, like at an autocross, where the Star Spec might have a minor edge (a few tenths perhaps on a 40 second course), I don't see any reason to buy the Star Specs. I had them on the M5 for 3 years -- they're great tires in performance terms but also that comes with noise and harshness that doesn't exist (by comparison) in the Super Sport. I only put 8k miles on them over the 3 years, so I sold them with 6-7/32 tread to a local friend. Oh, also, I had balance issues with them -- had them checked out on a Hunter roadforce machine, and the Dunlops were all "high" in terms of roadforce (in the 22-28lb range). They were never nicely smooth at speed.
The Super Sports on the other hand were literally perfect when balanced (very low roadforce numbers, one was 2lb) and took hardly any weights at all -- this is one of the reasons I really like Michelin high-end tires. I see no reason to buy the Star Specs as the prices of the two are very close also.

I replaced my PS2s with another set in August. I got 17,000 miles out of the first set and LOVED THEM! I had to call around to several tire dealers to find another set of PS2s and to my suprise a BMW dealer in St Louis had a set that were only slightly more than AutoTire quoted me on the phone. They are comfortable, quiet and perform well. I've been told getting that kind of wear and mileage out of them is very good! I run them at 39 psi all around.
I see that on the UK site. Looks like they are only importing 4 sizes in 18" diameter instead of the 12 sizes they make in 18". They even make 4 sizes in 17" which aren't shown in the UK. Looks like a marketing decision and hence will be almost impossible to change.
I guess is every E39 M5 owner in the UK made a request we might just get them to change their mind. If only something like a Ford Mondeo used 275/35 R 18's!
Best of luck to you folks over the pond, I just had these tires installed last week and they're fantastic. A bit more money than the Hankooks Ventus V12s I had before, but worth it. If these hold up 15-18K miles like the Hankooks, I'll be buying them again. The biggest downside is that the sizes seem to be more limited (couldn't get the 285/30/19 I had in the rear so I had to bump down one size to 275).
