370Z handling

[HerOuji]

hi to all Z lovers

i had a question for years since the day i owned a 370z(2009).

Everytime i drove her, i felt the steering wheel is acting wierd compare to other vehicle. It feels like the steering is moving to its own direction left or right when i enter to some minor uneven road and i have to really keep an eye on my arm because i need to react as soon as the steering turns( it doesnt turn much just a tiny small movement) but if i drive it for a long journey like 1h30mins it really bother me because my arm will be cramp controling the steering. sometimes really annoying.

so i wonder do any of you had experience with these problems? or is there anyway to solve these?

thank in advance
