Linking a video. The noise is produced during throttle inputs or braking. Forward and backward movement of the car. It is bad, and does it constantly. It will do it infrequently over sharp bumps. The issue has been there for a while and gotten worse over time. Car has a BMR adjustable UCA + mount. Stock shocks and LCA. Torque is to spec on the mount. Jam nuts on the UCA haven't moved based on visual inspection against a photo taken at time of install. I went over most of what I could get at easily with the seat cushion out. Car also has a DSS aluminum drive shaft. This is maddening. I hope it isn't an issue with the sheet metal. Anyone here have a noise like this before?
