Shaky trouble..

Alright so im getting some vibration at anything above 90mph after i let go off the accelerator but when im on it, either just cruising or wot, it wont vibrate but as soon as i let go the whole car begins to vibrate and its pretty bad.. i mean if i have some coins in the cupholder the coins will jump around..
it seems like its coming from the rear area or the rear half of the car... Any ideas what this could be?

Could be a long list of things, To include Tires need balancing, Driveshaft needs to be balanced or has debris on it, Transmission mount torn or bad, Motor mounts shot...

Could also be a bad u-joint.

Bro i have the exact same problem. I know for a fact its not tie rods or front end alignment. Cause I have had them changed. Mine started out at high speeds like yours now its at 60 & up. Whatever fixes yours let me know.

I was also thinking something with my driveshaft... My tranny mount and motor mounts are good and my tires are balanced, barely put em on a few months ago but i guess ill balance them myself at school... How would i go about checking my driveshaft? Could it be that the car is a little misaligned too? kinda pulls to the left..
