High rigidity comparable to a steel shaft, in a palm-sized package.
A new concept in body reinforcement that integrates the door and body.
When it comes to actively enjoying driving, the body is the key to supporting the driving experience. It's like the core of an athlete's body. That's why we've pursued the creation of a strong, unyielding frame by suppressing body distortion and twisting through reinforcing parts using high-rigidity oval shafts made of steel, which offer advantages in terms of rigidity.
The essence of it all is to allow the suspension to perform at 100% capacity and minimize the discrepancy between the driver's intentions and the car's behavior. That is the fundamental principle of body reinforcement as we see it.
The new approach they focused on was the relationship between the door and the body. While it might seem like a strong bond, in reality, the weatherstripping is tightly attached. To put it dramatically, the door is essentially hanging on the hinges, with a gap between it and the body, and it doesn't function as part of the frame.
This is inherently necessary since doors open and close by rotating on a hinge, but conversely, it can be said that a large opening in the shape of the door is created in the body.
When not installed
Therefore, a reinforcing part called a "door stabilizer" was developed to fill that gap and allow the closed door to function as part of the body.#1This led to the development of [the product/service].
The key to the mechanism lies in the plate with a sliding mechanism integrated with the striker. When the door is closed, the body-side and door-side plates overlap, automatically adjusting to eliminate any gaps in a wedge shape. The door and body become one, and the door, which was previously a panel separate from the frame, instantly transforms into a reinforcing bar.
This creates a robust body that suppresses even slight distortions and flexes that occur during driving.
When wearing
However, some might wonder if such a small plate, smaller than a business card, can really securely connect a large door to the body of a vehicle.
The key to this is the force pressing the plates together and the static friction force generated at the contact surface. When the door is closed, the wedge-shaped plates slide into the gap, creating a tight seal between them. The plates, with their high coefficient of friction, are pressed firmly against each other, preventing slippage and allowing even small parts to firmly connect the door and the body.
As a result, the vehicle's response delay to steering input is reduced. The initial sluggishness when turning is lessened, making it easier to stay on the intended line when changing lanes or entering corners. Corrective steering is also reduced, resulting in a more on-rails feel with less need for additional or corrective steering. In addition, the vibrations from going over bumps subside quickly, and any lingering vibrations after a jolt are softened, resulting in a firmer ride.
Installation requires no modifications to the vehicle; it's a custom-designed product. The striker side is a direct replacement, and the latch side is a bolt-on installation. Furthermore, the mounting screws are hidden after installation, achieving both mechanical functionality and a high-quality feel. As a part that catches the eye the moment the door is opened, attention has also been paid to its visual appeal, subtly enhancing the sense of ownership.
This product is compatible with a wide range of recent Mazda vehicles and comes in a package of two (one for each door). Two sets are required for 4-door and 5-door vehicles.

*The displayed price and estimated installation time are per set (for two doors, left and right). One set is required for the Roadster (ND), while two sets are needed for other compatible models that have four doors (front and rear).
*This product has been thoroughly tested for safety (ensuring proper door opening and closing function) when installed on compatible vehicles. If installed on a vehicle other than the compatible models, the doors may not close completely, potentially leading to damage or malfunction of the vehicle due to insufficient door closure while driving, or in the worst case, the doors opening while driving, resulting in serious accidents.
