DIY - Improve the quiet ride of the NX! (Video Before After)

[corradoMR2]

The NX is quiet, as quiet as the 3RX I had, but in the spirit of kaizen, why not improve it even further?

Sharing with you this video that includes a comparison in sound differences as well as sequential pics that outline the steps to the work. Not nearly as detailed as previous DIYs but hopefully it's pretty clear.

In scope:
~ 60% of the cabin floor.
~ 85% of the cargo sub floor.

Not shown but also done is the passenger side which is a repeat of the driver's side.

In short, tested like for like (same speed, road, day) I noticed a quieter cabin and am very happy with the result!

In case anyone is wondering, the Eco Cork Foam meets the Federal Motor Vehicle Safety Standard (FMVSS 302). I also installed it above the existing (should be fire retardant) underlayment so nothing directly on the floor near the exhaust or other heat sources.

In short, I'm comfortable with this setup, but of course if someone follows my video and has issues, I have to throw it out there that I cannot be responsible and that the person assumes the risk. Common sense disclaimer...
