A&Q about 350Z
Q:
it defenitly would not hurt.
A:
it may sound l silly, but the road noise and the whole trip sometimes gets on your nerves and this could be it too. Other than that maybe putting a thicker tranny fluid might help.
A:
The noises I hear are my bones cracking when I get out of the car. It is very nice driving around town, but I certainly dont want to take my track model on any longroad trips.
