Installed the GCS Shark Fin, I should've set the 3m tape all the way to the edge. I don't like how the base was flat because the roof has a slope.
Installed new doorstops to stop the door shutting on me.
Found 2 sources of rattles whenever I accelerated/braked:
Used a cheap endoscope from aliexpress taped to a magnetic stick to find that black bolt in there ~
