Exactly what I was looking for, Mark! I don't live near a dealer, and I had to travel 100's of kilometres just for the tracking, as I had new tyres waiting to be fitted. The local wheel alignment people didn't have the GT-R in their software.
Thanks very much. The 2014 in the USA is the 2013 European model I think, but will be in any event the same as my 2012 car.
Thank you Mark - it is the same. The dealers set it, so I suppose it is for street use. I don't race her anyway. That's how I got more than 26,000 kms out of the first set of tyres.
The Nissan dealer told me that the tracking should be checked every year. I don't think it was the first year, but I am not sure. I think the tracking went off when I drove up the Pyrenees in the summer at a little more than a leisurely pace. Pulling 1.5g for a period of time does it, I think, but one only lives once. I had a bit of extra wear on the inside of the tyres, but the front only had a couple of thousand kms left in them, probably 4k on the rear, but all the tyres need changing at the same time, so there it is.
