Hello all Gs owner i have a 2006 G35 coupe 6mt, so the noise i am experiencing happen a few weeks back and i finally have time to post about it. While i am in first gear driving to about 1800- 2500 RPM i hear a slightly scratching noise it does not happen constantly just once in awhile and it usually happens almost if not all the time in the morning. I will post a video of the noise once i get my camcorder back as for now hopefully i can get some sort of help. Thank you
