Just a few days ago we got some lo-fi images presented as a video of the 2013 Nissan GT-R testing on the 'Ring. Now we've got hi-res spy shots of the same session.

The new car is rumored to be packing 570 horsepower and the carbon-fiber trunk and wing signify that Nissan is finally taking care of that little weight problem everyone's been mentioning since 2009. There's also a new front splitter with additional cooling ducts and side skirts.

The wheels on this car are also different front-and-rear which likely means that they're playing with new wheel sizes. Currently the GT-R sits on 20-by-9.5 inches front and 20-by-10.5 inch rear wheels running P255/40R20 and P285/35ZR20 respectively.
