I have tried the z8's but they were not model specific. This is my tire of choice. First let me tell you that mileage is not the most important factor for me when choosing a tire. I never get the kind of longevity that some on here talk about. (4500 on pr2's) For me grip and feel are the most important thing and these are great. They are the most confidence inspiring tires I've tried yet. When leaned over they are very nuetral and will hold your line. Do not stand up on braking. Very sticky. Read what thier website has to say about the z8 constuction. It works.
