A dvd of 1 track day doesent really mean squat especially if the whole thing is in japanese.
In the GTR special edition best motoring dvd they race a 34,33,32 GTR's and a G35 on a track and the G35 beats the R32 as the R32 has oil cooler problems and keeps overheating and has to keep slowing down. If it didnt have english translation you wouldnt know and would think the r32 was a piece of shit.
Then there the best motoring drivers. Gan San is a mad man and if he was driving the gtir the other drivers usually stay out of his way
