Droaning and resonance in the chassis

got a chance to ride in the rear seat of my car during daughter's learning curve.

I noticed that the back window vibrates pretty good and that the droan I hear in the driver's seat is not the same in the back. Its almost like the driver's position is perfectly placed to pick up the resonance. The glass vibration only started at around 35 mph and up.

After parking I checked the body and the rear quarter panels vibrate pretty good as does the trunk/spoiler. All this resonance vibration seems like it could be eliminated with some cleverly positioned dampening material.

Beyond rear shock mounting bracing, has anyone tried other things to quell the vibrations????

i know what you're talking about...

i get even more rattles and stuff when i roll over bumps

only thing i did to prevent trunk from rattling (especially w/ the subs) is extend those little rubber bumpers out a bit more

other than that.. not a clue...

I bust ARP bolts by hand...
