Vibration at certain speeds

Hey guys, my 07 coupe manual has a vibration that occurs at 60km/h and then disappears but at about 90km/h it comes back with a vengeance and doesnt go away and just gets worse the faster you go. Nothing is shaking but a pretty solid vibration that is hard to ignore. It's got fairly new Pirelli P zeros and i've had the wheels balanced at Bob jane. I took it back after that didnt fix it and they they thought it was hub spacers/rings missing but that didnt fix it either. Anyone had anything similar? I'm guessing its driveshaft related as it feels like the rears are where the problem is. Any help or a place to take it to that knows what they are doing in Brissy area. Cheers guys

Could be the bearing on the hub that is becoming more prominent with increased speed.

You say you feel like it's coming from the rear.

Any noise? Feels like it's on one side or both? 

Are you able to jack it up?

 These symptoms could also be caused by any one of these:

warped rotors, bad shock, bad bushes, an alignment issue, bad body mount, trans or axle mount or even too much play in the drive shaft or diff..

I know when it happen to me, it started only when driving but it took a while then it started to get worse when braking..

For me it was just warped rotors in the end..

It feels like both sides. There's no additional noise as the exhaust is very loud anyway, but it gets pretty bad over 120km/h as in cant see out of the rear view mirror. How do i go about checking the bearings?

Driveshaft.

Get it to a mechanic and up on a hoist.

It would suck diving at 120km and the driveshaft comes though your passengers foot wells
