Dynamatted hatch and doors. Installed 2" foam in hatch. Replaced Yoko tires with Pilot Super Sports. Noise is down about 6 dB. Still sounds gravely on smooth asphalt and harsher sounding on grooved concrete slabs.
I checked the firewall and there is factory 3/8" pad that goes under seats. I think some the noise is coming through door seals (they are good and tight). Too bad more can be done to cut the noise.
