I live in Japan, and have seen/interacted with 4 generations of skylines (R31-34) and 4 of GT-Rs (R32-35). They are great cars for what they are built for, which is to tear it up on the racetrack. In any other motorsports situation (Winding road, Gymkana, Autocross), there is better options- such as the STI or Evo. I don't like how much they weigh, or that they are so complicated. They are not as supported by the tuning community as the 34 was due to the complexity of the platform.
