[Chopstick]

So after a recent trackday (I spun off the track) I've been hearing a weird clicking noise coming from the passenger rear of the car. Its definitely a clicking sound that is pretty rapid. I comes and goes independent of the road. In the afternoon when I get off work the sound can best be described as small pebbles bouncing around (This sound is significantly quieter than the clicking sound). The sound also does not more quiet when i put the rear seat up.

I've already tried the rear deck pop fix and I lubed basically every possible nook and cranny in the trunk.
I've double checked the tightness on the rear passenger coil and everything connected to the LCA and lubed everything down there.


Any ideas on what it could be? I'm out of ideas.
