car vibration?

[trolly]

i'm rather new to this forum, the porsche world, and owning a car. there are a few questions that i have to ask about my current car. my car seems to vibrate, though i feel nothing at the steering wheel. i dont think it is the engine, as the mounting brackets have been replaced, but can't be entirely sure. when i first began driving this car i used to believe my cellphone was vibrating and would frequently check my pockets.. any ideaS?

also, could people who've read this post read my "testing" post...it actually isnt a testing post but a post about the worth of my car to people who know nothing of cars. also toward the bottom there are a few ps's, there are some more questions there that i would like to know or read some opinions on. thanks

vibration points towards the engine mounts, but you've already checked them. It can also be the balance belt, i've had one that jumped a few teeth and vibrated at about 2500rpm, check tension, and replace belt if needed. checked out the testing page
