Very similar setup. Guess I'll try some horse mats. How about these? "Utility Rubber Mat, Black, 4 ft. x 3 ft x 1/2 in."

Those look good. Half as thick as mine, but they may work well.
Plywood is a poor sound blocker. Hit a sheet of plywood with a hammer and it rings like a bell. It's resonant. Hit a sheet of rubber matting and you'll be hard pressed to hear the hit. Non-resonant. Plywood is also reflective of high frequencies.
Another place to install good noise blocking is in the B-pillars. They're right next to your ears.
