hi im pretty new to the forum and i was at the track recentley with my 03 350z and its completley stock and when i get to about 100+ mph the car seems to rattle alot or feels like it shakes. Any rememdy for this or likley causes???

 

sounds like you need to have your tires balanced or maybe a bent rim?? go faster and maybe it will go away......lol

 

+1... plus, turn off your hydraulic system when driving at that speed...jk

 

get a mercedes?

 

Can be worn tires, improperly mounted wheels or alignment.

 

yea i was actually thinking tires cause my backs are starting to get alot of wear i just wasnt completley sure if it was normal for 350z's to do this.

p.s the new audi R8's are not that much faster around a track than my z haha!!! videos later!!!

 

I think you need more power. If all else fails close your eyes and smash down the throttle
That would probably fix your problem 8)
