[M&Ms]

There's the PS4 and the PS4S. The latter is the replacement for the Super Sport, and exceeds the SS in performance and longevity. The PS4 is also a great allrounder, but not considered to be UHP. I went through 2 sets of Michelin Super Sports on my GT, but found they wore quite quickly, and lacked the straight line grip from zero, with an awful screech to boot (they did perform well driving the Putty road corners though!)

I had the PS4S on my XR8 for about 10,000 km before I traded it in, and they still looked and drove like new. They did take around 1000km to fully bed in, but once done, grip and drive was phenomenal. Highly recommended as I believe they are the best of the best when it comes to performance tyres.

I'll be trying the Goodyear Eagle F1 Supersport on my Alfa when the time comes, as unfortunately the PS4S does not come in 285 width. I hear these new Goodyear's are just as good.
