welll today the weather was to great to pass up so and some freinds decided to go for a sprinted cruise around the city. well i got up too 100mph and my steering wheel started to shake a little. I mean 350z arent that old of a car. so i don think it should be doing that. does anyone know why it might be doing that? maybe my tires or suspension or alightment?

 

Probably the road is bumpy or the tires are out of balanced. What are you doing going 100 in the city?

 

try getting your tires balanced.

 

Very stiff suspension could be reacting to the little bumps and humps on the road at those speeds.....that is if you aren't running the stock setup.
