I'm curious about that as well. Frame less mirror looks nice. Wish it had the mirror option to use as a camera to make it easier to see out of the back windshield like some of the newer Nissans do.
I've been using a set of blizzaks for the past few years but there are lots of other options. A good place to start would be looking on tirerack website. That's where I got mine.
I personally like putting some extra weight in the hatch just to settle the backend down in winter weather. Life's too short to not drive this machine year round. So throw some winter tires on and have at it. That's my plan!
That's my order as well. Wanted the gun metallic until found out it doesn't come with the black roof. Just don't like the way the new Z looks without the black roof. Maybe gun metallic and black roof will be an option on the Nismo.
Sounds pretty good. Definitely seems to have the performance down. Hopefully the same can be said for the traction. Hate to have all that power and not be able to get it to the ground.
