Help me get rid of the annoying vibration

>600lbs, thats incredible, that must hurt your cars performance a lot. My car would run so slow with that much added >wieght.

Its amazingly fast actually. It gets better with age. I didn't hardly notice the weight because it is made to cruise carrying  a full load at around 100-140mph in europe. But I personally know that it can go at least 20mph faster though Nothing like the desert when you need to blow out the cobwebs.

I did install new stock springs in the rear so it wouldn't sag.  

Good deal man. Ha, my car is lucky to see the governed speed as it is, a measily 118mph. My suspension is rock hard, i have bilstien coil overs all round and they dont allow hardly any bounce, but i like grippy race car like feel so its all good.

You would not need near that much. I would estimate 1 bulk pak/36sq ft of Dynamat Xtreme. Anything else, get 70sqft.

FYI:One bulk pak of Dynamat -X weighs 90lbs
