Ahhh, left out the Goodyear Eagle F1 GSD3:
Quite a good tyre for the money, the compound is harder than the BS S03 and Dunlop SP Sport Maxx.
Due to the harder compound, these tyres should be very durable; which is also indicated by the 280 TWR of them.
Grip is very good, and the tyres hold up very well, even on the track. With the long and thin tread pattern I would expect them to squirm a bit under hard cornering though.
If given the choice, i would take the Dunlop SP Sport Maxx or the BS S03 over the GSD3.
I've heard unconfirmed stories that the German GSD3's are better than the Australian made ones.
