Thanks Robbie - I'll check them out. How long is not long? Generally I'll be happy to get 15,000km out of them.
I had them on another set of rims for track days only and after 5 track days there pretty much shot, but one of those days was at Winton and consisted of 200km distance wise, which really took alot out of them.
On the street you should see 15000ks out of them if your frontend is in good condition and aligned correctly.
I don't have any expirence with the other tyres you listed so can't really comment on them other than that no one i know uses them for whatever reason.
