So the rattle source was the long control arm that connects the suspension to the body down the side of the car. I found a guide to repair the ball joint and spent a couple hours last weekend following that process. Tapped the sleeve that the ball sits in and injected some new grease into the joint and the noise is gone from that side completely. I noticed now that the left side actually makes a little bit of noise as well when warm but the right side eliminated 90% of the noises the car made over bumps. SO much nicer to drive without that noise.
The best way to describe the noise to determine if you have the same part going bad is a loose bolt shaken in a cardboard box right behind the passenger seat.
I also got my Michelin Pilot Super Sports installed up front and they make the falken tires I had feel like they were made out of plastic as far as grip and ride quality. An alignment and the new tires with balance completely eliminated my steering wheel shake at 70-75ish.
