【Custom】Installed on the inside of the interior panel! Achieve a “silent drive” with the application of the tuning sheet
If you want to quietly enhance the interior of the Copen──what you want to install is the “ADVANS Tuning Sheet” created by D-SPORT and BEWITH. With a three-layer structure, it aims for overwhelming quietness and improvement in audio quality.
The Copen's roof enhances the cabin environment
Equipped with an electric opening and closing roof in a compact body, the Copen allows you to enjoy open driving with ease. Since it's a car meant for enjoying driving, there are times when you might think, "I want to make the interior a bit more comfortable" after having it for a while.
What caught my attention was the "D-SPORT × BEWITH ADVANS soundproofing sheet." This is a vibration-damping and soundproofing sheet developed by D-SPORT and the audio specialist manufacturer BEWITH, designed to be installed on the roof of the Copen.

3-layer structure to reduce unpleasant noise
The contents of this sheet have a three-layer structure. It consists of a sound-absorbing layer that absorbs sound, a sound-insulating layer that blocks sound, and a vibration-damping layer that suppresses vibrations. The sound absorbing layer uses a material with a semi-continuous bubble structure, designed to handle a wide range of noises from muffled low sounds to bothersome high sounds.
With a thickness of 9mm, it's slim enough that you won't have to worry about the interior of the car feeling cramped after installation. As the quietness increases, you can even hear the finer sounds of the audio that you didn't notice before. It's also a concern for those who want to cherish the music during drives.

Custom shape specifically for the Copen makes installation easy.
It is also characterized by its custom shape designed to fit the resin roofs of the LA400K/A and L880K. Installation involves removing the interior panels, adjusting the size of the sheet to fit the installation area, and affixing it. The reference installation time is approximately 1 hour for the LA400K/A and about 2.5 hours for the L880K. A standard utility knife or scissors can be used for cutting.
Additionally, an important point not to be overlooked is that the roof's opening and closing mechanism can be used as is after installation. You can enhance the interior environment without sacrificing the unique open-top driving experience of the Copen, which is quite appealing.

Enjoy the drive even more in a quiet cabin.
Customizing the exterior is fun, but customizing the interior for comfort is also a mature choice. In a quieter cabin, the heartbeat of the engine and your favorite music should feel even more vivid. Owners who want to make their holidays in an open car even more comfortable should check this out.
