My MPSS are at 5mm with 12000 miles done so far, including a trackday so I'm hoping for at least 20k miles before they need changing. Although I wonder if I could wear a set right down to slick to use for trackdays 
The F1A2's on my previous RS6 also did about 18000 miles including trackdays so on par with the MPSS I'd say.
