From a small spoiler that can be casually fitted with an add-on, to a front nose that replaces the entire bumper and renews the image of the car, we offer options according to the user's preference.


ND-07 Styling kit

Commercially available aero parts for sports cars tend to have wild designs that emphasize flashiness, but ND styling kits maintain the quality of mass-produced specifications and provide total coordination for the entire car. Front under spoiler and trunk spoiler that do not require painting and can be used as is from the bumper of a mass-produced car. In combination with the rear side cowl, it creates a sporty form with a light feel. By installing a spoiler, the clearance with the road surface will be reduced by up to 15 mm, but this will not be a problem unless there is a large step.

Obtaining an agile and stable ride

For example, at the corner of a mountain pass or a lane change on a highway, the car reacts as the driver wants and turns in a stable manner.Suspension tuning to maximize such ride quality is not just to stiffen your feet, but to flexibly grasp the unevenness of the road surface and stabilize the posture of the car.We have a lineup of nostalgic items for drivers who want to actively enjoy driving, including the Street Sports Suspension Kit.

Street Sports Suspension Kit (KIJIMA-SPEC)

A height-adjustable suspension kit that embodies the best street ride, supervised by Takao Kijima, who was the authority on suspension development during his tenure at Mazda Motor Corporation.A balance between sportiness and ride quality is achieved by combining a damper that exerts damping force firmly from the moment the car starts moving and a spring that is about 10% stronger in hardness.The vehicle height can be adjusted based on -15mm, which takes into consideration both the low center of gravity and usability.There are plenty of options such as stabilizer links to further refine your driving.

Roadster Street Sports Suspension Kit Kijima Spec
Damping ratio data

Well balance of sportiness and ride quality
* Damping ratio (conceptual diagram) is the ratio of the effect of the damper to the hardness of the spring.By increasing the rise of the damping force in the very low speed range of the damper, which greatly affects the initial roll control, and gently lowering the subsequent range, the deterioration of riding comfort is suppressed while suppressing the roll feeling.

A sense of unity that trains the body

A solid sense of stability that is transmitted to the driver through the steering and seat.The source of driving with a sense of unity is the body reinforcement parts that train the core of the car.Various items that strengthen the body in all directions, such as the strut tower bar in the engine room and the member brace that solidifies the entire floor, suppress the slight distortion of the body that occurs while driving and bring out the full performance of the suspension and tires.


Tower brace set / member brace set

Even with the high-rigidity body of modern cars, slight distortion occurs during driving, and human sensibilities have the ability to perceive it as a delay in reaction when the steering is turned off.For the Roadster, we have set up a brace set that reinforces the front and back of the body like a sandwich from two directions, not just the general strut tower bar.Not only on the pass and at high speeds, but also on the streets, you can fully feel the hard and firm response that does not make you feel the open body.We also paid particular attention to the functional design of the bright red color, which is expected to have a tuning effect from the appearance.

Instant power up & well sound

From the moment you step on the accelerator, the engine will blow up linearly with a nice sound.In the streets where frequent stop and go and delicate control in the normal range are required, not only peak power but also instantaneous response is important.An air filter that suppresses intake resistance and a highly efficient muffler that creates a sporting sound that suppresses tunes the invisible air and makes the engine react lively.

The feeling of stopping at will

It stops exactly at the stop line as you imagined.In a scene where you approach a winding corner at a speed with plenty of room, it is important not only how the brakes work, but also how they work.The aim was to feel that you can decelerate at will no matter what speed you step on repeatedly.Brake pads with carefully selected friction materials and items that increase the rigidity around the pedals provide the effect of synchronizing with the sensibilities.


Street sports brake pads

When I stepped on the brakes, the car ran idle more than I expected, and I felt a little sick.Also, even if you step on it a little, the brakes will be too effective and the body will be crushed ... This is an extreme example, but even if safety is ensured by ABS or automatic braking, the driver thought If the brakes do not work on the street, you will not be able to concentrate on driving.The aim of the street sports brake pads is to feel that the vehicle speed drops as the driver presses the brake pedal from the usual intersection to the highway and the pass.It has a reputation for its natural effect, with less aggression to the brake rotor and less unpleasant squealing noise that are typical of sports pads.
