this isnt anything new from nissan. Chevy called them out on the r34 times when they supposedly broke and set a record on the track. They ended up finding out that the car that broke the times wasnt a stock gtr it was one with modified suspension and racing rubber. They proved that some version of the corvette was faster then the GTR. Nissan has been doing this for years with their GTR. To be quite honest I dont see the hype behind the gtr. The R32 was bad ass for its time the 33 was ass and the 34 was pretty good.
To this day I will take a rx7 over a GTR
