Tapping/Rubbing Noise driving me crazy

I have a tapping noise (6+ months now) I hear it while driving on or off the accelerator. It's a steady clicking/rubbing sound, almost like the sound a baseball card would make attached to bicycle spokes (old school). On inspection everything is clear of the drive train and wheels.
At first we thought it was the tires rubbing the wheel wells from it being lowered because the springs have sagged over time. I returned it back to stock but the sound remains.
Anyone aware of a known issue or have an idea where I can look. It's a 2016 Hellcat Charger with 36k miles on it.
Otherwise the car has been a dream to own and drive!

The sound is like Chinese water torture and is driving me crazy! Thanks!
