Detailed Description

If you own a Toyota GR86 or Subaru BRZ, you may have heard a loud crack or pop from the window when opening or closing the door — right when the glass automatically drops slightly. 

This tiny washer provides just enough spacing to relieve the stress, stopping the cracking noise instantly.

Installation Overview

You’ll need to remove the inner door panel — search “GR86 / BRZ door panel removal” on YouTube for visual reference.

Install the washer between the two metal brackets — not under the 10 mm nut you remove.

Reapply Loctite, as the factory washer had.

Reassemble and test — no more cracking noise when the door opens or closes.
