Introduction of noise was prevented by inserting urethane foam inside the centre pillar.
Introduction of noise was prevented by adding acoustic foam materials inside each pillar, side roof rail and wheel house arch interior.
High rigidity foam materials were added inside the front sidemember (right side) and rear floor sidemember to heighten panel rigidity.
CAUTION
The foam materials may burn when heated. Always observe the following instructions.
Never use a gas burner or burn the areas using foam materials.
When cutting the parts using foam materials, ensure to use tools (air saw, etc.) that do not generate fire.
If there is residual foam materials remaining on the cut section (body side) then weld after removing the foam materials from periphery of the welding area.
