Hello Tonybell_57, thank you for your input, much appreciated.
Everyone, I would like to thank you for all your valuable input, its great to see the 370z in action trying to provide a fix.
Reeps!!! I Cant thank you enough for suggesting "Good Roads" now "Elite Roads". my problem has been fixed, believe it or not, it was something so simple that i couldnt belive it myself!!!!!! it was as simple as a tire balance with an "index" adjustment!!!!! problem fix, my beauty is smooth as silk and i'm a happy 370z driver again!!!!!!
once again, thank you All for your input, much appreciated.
