We all know that you can't get ES02JZs for love nor money these days - but it looks like S02JZs are still available and in 245 width for the rear. A little down on the speed rating maybe (but still just within the actual top speed of the car - unless you have a supercharged S2K on an autobahn this isn't going to matter), and the sidewalls may not be quite the same on the rear. But the compound and width are OK so these tyres may well be the way to go if they really are available as the website states.

 

i think those are Porsche Fitment
