Hey guys, I recently, well ,last year, bought a g35 coupe. I didn't really pay attention to it that much until now.

Squeaking sounds emerge every time i drive thru the vi-dock which is pretty bumpy.

Here's some info on the car,
2004 G35 Coupe 6 M/T w/ 48k miles.
It's got Tein H Tech lowering springs and a Motordyne VQ exhaust..

Is this noise caused by the springs? (They were already installed)

Thanks
