We are very pleased to have received so much positive feedback and anticipation for the "door stabilizer" that we introduced the other day.
At the same time, we've been receiving a lot of inquiries such as, "How exactly will it change things?" and "Will it fit my car?"
So, this time, I'd like to explain in a little more detail about the "changes in driving performance," the "mechanism," and the progress toward the launch.

The goal of this product is to significantly increase the rigidity of the body and make the car's response to steering inputs more linear. To put it in more familiar terms, it's about improving the feeling of oneness between driver and car. The aim is to create a feeling of being able to control the car exactly as you intend, without the car's behavior being delayed or, conversely, excessively reactive to the driver's expectations.

For example, it feels like the car changes direction by the exact amount you turn the steering wheel. This dramatically reduces the need for "unnecessary operations" such as turning the steering wheel further or straightening it when changing lanes or going around curves, making it much easier to stay precisely on your intended line.

In order to create that effect, we focused on the "tiny gap" between the door and the body.
Last blogAs I mentioned earlier, when the door is closed, it's actually a rubber product (weatherstrip) that's in contact with the body's frame itself. It may look like it's firmly attached, but in reality, it doesn't function as part of the body (frame).

The solution we adopted was to incorporate a unique "spacer" into the striker section and implement a mechanism that automatically adjusts this gap to zero.
This allows the doors to function as "part of the frame" connecting the pillars without modifying the vehicle itself, thereby improving the overall rigidity of the body.

This mechanism allows for flexible adaptation to individual vehicle differences and is widely compatible with recent Mazda vehicles (generally from 2012 onwards).
However, there is one regrettable point. Due to the different shape of the mounting hardware, it was physically impossible to install it on older vehicles. We sincerely apologize to everyone who was looking forward to it, and we hope for your understanding.
