65+ on highway car starts to vibrate it feels like my 2 back tires are not balanced, but i assure you i balanced them and thought it would fix the problem bu it didnt, starting to get annoying, i rattled the bolts on my exhaus loose and i had o tighten that up, jus annoying..when im on the expressway goin around 65 or 70 theres a vibration u can see my passenger seat shimmeing a litle bit, butwhen i get going around 80-85 it kinda stops....anyone have a clue? maybee shocks? or warped rotors?? i know i jus redone my front brake and the rotors were warped and i had to freakn buy 2 new caliper brackets b/c one of the bolts seized in each bracket, wierd, i would think thats a defect in the camaro, but who knows??hey were 125 a piece...ridiculous for having o change your brakes for the 1st time...anyways...lemme knowon the back?

rule of thumb:
"if it shakes the bottom of the seat, its a problem out back"
"if it shakes the steering wheel, its a problem out front"
I would check the rotors, u-joints, check your rear tires for uneven wear. Even over or under inflation.

If you find out what it is please post. I have the same issue and have rotated tires, done alignment, etc. and hasn't changed. Ever since the clutch and transmission went in. It's not as bad as your but still noticable. It's not dependent on rpm but speed otherwise I was thinking it could be the poly motor mounts. Driveshaft maybe?

I think you might have a bent wheel(s). I have been experiencing the same problem. When I had my BFG KDw's mounted last week the tech called me over and showed me the wobble in a couple of my wheels. Apparently they can still be ballanced even though they are slightly bent. I am taking my wheels to have them possibly repaired.
