In today’s video, I’m upgrading the Toyota GR Yaris with my ultimate 2-door sound deadening package. This setup is designed to significantly reduce rattles and road noise, improving overall cabin comfort and making the GR Yaris a more refined daily driver — without adding unnecessary weight.

Doors Soundproofing
We found that the GR Yaris doors have minimal sound insulation materials. Given their size and surface area, which make up a significant portion of the vehicle’s side profile, they would benefit greatly from proper sound deadening.
Doors SoundProofing
As part of our standard process, both the inner and outer door skins were treated with STP Intrigo and STP Aero for effective sound deadening.
The door trim panel was lined with soft STP Biplast to eliminate contact points, while STP Bitplast was applied around the perimeter to reduce potential rattles and ensure a solid, refined finish.
