..More hours than I wanted on two bolts..

As for new what did I do with my Z:
Put some hushmat on license/frame, looking to add some sound damping material to the whole hatch area next.

I just did the hatch area with their Onyx product, and I am incredibly pleased for the price; I still need to do the doors, which should decrease the road noise even further. For now, I can actually hear phone calls in the Z at highway speed. Check the link in my signature for pictures of my install. PM Pintsize or GT Mat for information on the product and pricing
