I will go for the same size the manufacturer installed , 215/45/17 . I was actually tempted by the Tirerack price , the Dunlops are 133$ US a piece .Price is also a factor in my decision .The Potenza RE-01R are much more expensive .Last year I got a set of Contisport Contact 3 but I'm keeping them for day-to day driving . I got them for 149$ US each . I will use the Dunlops for the track . I loved my original Conti's but they're just worn now so I'll have to be more careful on the track if I don't want to take the tow truck back home .
But question is : has anybody used the Dunlop Direzza Z1 Star Spec or know someone who's tried them ? I wonder how do they behave and how long did they last .
