■Upper mount bush set
Mass-produced product with 127% increased rubber hardness. A set of 8 for one vehicle, to be attached to the top mount of the damper. It suppresses the bending of the rubber from the moment the damper starts to move, supporting the quick rise of damping force. It is recommended to replace it at the same time as replacing the suspension. >>Learn more
■Suspension bush set (upper)
Mass-produced product with 125-146% increased rubber hardness. Set of 8 parts including front and rear upper arms, lateral and leading links. While ensuring practicality, it suppresses the bending of rubber in moving parts, supporting accurate handling. Individual parts can also be purchased separately.>>Learn more
■ Suspension bush set (lower)
Mass-produced product with rubber hardness increased by 109-140%. Set includes 8 front lower arms, rear trailing/toe control/lateral link, and 14 rear axle parts. While ensuring practicality, it suppresses the bending of rubber in moving parts, supporting precise handling. Individual parts can also be purchased separately. >>Learn more

More than a sports car, but not quite a racing car. A mass-produced product with tuned rubber hardness.
To actively enjoy driving, it is important to communicate closely with the car. When the driver senses input from the road surface and steers, the car's movement is corrected. The driver then senses that movement and repeats the next steering... this closed loop must be completed swiftly and accurately. To achieve this, we have released a number of body reinforcement parts, but we have focused on rubber bushings that are installed in the moving parts of the suspension.
The rubber bushings used in mass-produced cars, even in sports cars, must be made softer to ensure comfort, and vibration absorption must be prioritized. This means that when driving on winding roads, there is a momentary delay in response to the driver's input. The ND Roadster, which is equipped with a double wishbone front suspension and a multi-link rear suspension, has more than 30 bushings scattered throughout it. It is easy to imagine that making these bushes harder would have a major impact on handling.
The key is to get the hardness just right. If you replace it with a metal ball joint or hard urethane like those used in racing cars, the rigidity will be maximized, but in exchange, vibrations and operating noise due to aging will occur, making it unsuitable for street use. On the other hand, if it is too soft, the response will be dull.
Our suspension bushings maintain the mass-produced shape while increasing the rubber hardness by 110-140%. They ensure practicality while suppressing the deflection of moving parts, creating solid handling that is more than that of a sports car, but less than that of a racing car. The lineup is based on the upper mount, which enhances the movement during the damper's small stroke, and the lower arm side, which bears the load, and includes all the moving parts of the suspension up to the upper arm side. We hope you will identify the points to strengthen according to the driving stage. Of course, we also recommend them as a way to refresh your beloved car that has accumulated a lot of mileage and to tune it up to be more sporty.
