Functional Parts

▶Suspension Parts

“A New Driving Sensation” – Suspension is the core of full running sports sensation.Our aim is handling at will, beyond the boundaries of mass-produced vehicles. For drivers who want to actively enjoy driving, not only the matter of simply stiff or soft feeling, but to be provided the best street driving specification which has refined the dynamic sensitivity performance such as the initial responsiveness at the time of steering and the transient characteristic of rolling.

Parts lineup

■Low Down Spring
The roll is placed under control by the spring rate intensified within the range that has less impact on a ride quality, so that the vehicle height can be brought down by approx. 20 mm.  For the riding taste, the car stability is improved by bringing its center of gravity down, which provides a desired tendency to the “person who enjoys driving.”  Moreover, the clearance of tire house becomes reduced, which makes the whole car look low.  As a result, a dynamic feeling is provided to the styling.

■Sports Damper
The damping force of the rebound side in particular increased in comparison with the standard car controls the postural change.  The damping force of the bump side that causes the unpleasant jolt to worsen is almost as same as the standard car.  Further, the adopted dead low speed valve that moves smoothly when it starts to work controls the car posture properly from the extremely low-speed area.  As a result, the comfortable ride quality with less roughness and the sporty driving feeling go hand in hand.

■Street Sports SUS. Kit
The best street model anyone could ever think of for AutoExe. Based on dynamic sensitivity engineering, twin tube damper quickly initiates damping force at a very low speed region and controls the rolling response. Vehicle height is set for a 15 mm standard which realizes linear handling without impairing riding comfort.

Adjustable Stabilizer Link
The length of the stabilizer link is designed with using the factory standard car as a guideline.  Due to this, when lowering the car height, at which time the angle of the lower arm changes, there is a tendency for arm angle of the link and stabilizer becomes more acute than the appropriate value, which spoils the true stabilizer effect.  The Adjustable Stabilizer Link is an item which allows the true stabilizer functionality to shine through by adjusting the link length when lowering down, so that the arm angle of the stabilizer is kept at the appropriate setting.

Sports Stabilizer
The spring rate increased by the pipe diameter greater than that of the standard car reduces the roll at the comer.  It is not supposed to work as a spring when the right and the left tires go up and down simultaneously during straight-ahead driving, etc.  Therefore, worsening of ride quality is minimized.

Body Parts

In order to increase the sense of unity between the driver and the car, tuning to train the body is fundamental. By decreasing the slight distortion of each part of the body generated by, for example, the force on the road surface while turning a corner, the motion of the initial operation of the suspension which was absorbed by the distortion is pulled out, enhancing handling with a sense of direct reaction from the moment you turn the steering wheel with no delay.

Parts lineup

■Strut Tower Bar
It is a welded one-piece type with cylindrical rib that binds together the upper sections of the right and the left suspensions tightly with the strong steel pipe and plate.  It reduces the distortion of the body applied from the suspension to ensure the movement of the suspension.  As a result, it creates a zippy feeling of driving a car.  All the more because it is part of the basic item, we stick to the function-oriented stance.

■Floor Cross Bar
It is a newly conceived reinforcement part that reinforces the floor by binding the right and the left sides of the rear floor with a steel pipe.  It produces the effect close to the tower bar without almost sacrificing the ease of use of the luggage room.  It concurrently uses the high-intensity bolt, etc. of the seat for installation, and won’t cause any annoying burden on the body, either.  We particularly recommend that it be installed together with the front strut tower bar.

■Lower Arm Bar(Front)
It uses the steel pipe to reinforce the right and the left bases of the lower part of the front suspension that greatly affect the steering.  Reducing the opening of the section where the suspension is attached to control the alignment change, it increases the secured sense of steering.

Intake & Exhaust Parts

For intake / exhaust tuning which has a direct impact on comfortable driving, improvement of peak power has no significance, but the reaction to instantly transmit the driver’s intention to the car.  Accelerator response is improved based on the air filter and the muffler with moderately reduced resistance. A discreet sports sound deepens communication between the driver and the car.

Parts lineup

■Air Filter Replacement
Used to replace the filter components but which allow utilization of the original air cleaner box. Dry nonwoven fabric that does not affect air flow sensors is used for the filter material. The specifications provide a good balance of ventilation performance and dust filtering. In addition, stainless mesh, which is not available with the original products, reduces any deformation of the filter medium at high engine speeds, while also easily and effectively improving accelerator response. Its disposable design also makes it easy to maintain.

Ram Air Intake System
It is structured to take in more fresh air as the car runs more distance with the air intake directed forward the car.  Fresh air is not only efficiently taken in through the dedicated efficient filter, but also the insulation-efficiency and high-grade carbon is used in the main body.  Therefore, it produces the effect close to an incensement of engine displacement.  The sound of air taken in that you can hear even inside the car is comfortable, and your feelings of driving also run high.

■Premium Tail Muffler
Profound feeling with sophistication is the fascination of this series. An oval shaped tail end of 110X95 mm is exactly what is needed for a refined touch. The gentle sport sound that is controlled and muffled for driver and passengers, and improvement of accelerator response within a practical range, are coexistent with the large-capacity, straight-through silencer, in which a slightly smaller main pipe and inner structure are carefully tuned.

Brake Parts

The cardinal point of the brake is to stop the car safely. The secondary expected function of the brake is easy control for the driver to freely reduce the speed of the car so as to enjoy driving as one wishes. As for sequential braking, it performs so as to synchronize the sensitivity of the driver using the brace for which delay reaction of braking can be solved by strengthening the rigidity of the mounting section for the pedal and the brake pads with a small change in the coefficient of function.

Parts lineup

■Street Sports Brake Pad
“Deceleration of at will”, it is our goal. Not just for the performance in stopping, the design focuses on the stable effectiveness at the time of continuous braking, meticulous load shifting while cornering, giving very flexible control of the vehicle speed. On the assumption of driving on the road, the coefficient of friction (μ) is constantly changing depending on the conditions such as breaking actions, speed of the vehicle, and temperature, etc. The variation of such changes and how it changes became our interests. Sport-oriented drivers’ sweetheart, “transient property of μ”, generates spice which synchronizes the sensibilities.

■Street Brake Rotor
Street brake Rotor has the same one piece structure as the mass produced rotors.
Content of carbon and silicon have been changed to strengthen the component.
Moreover, metallic bond formation is stabilized by a thorough heat treatment process, which is abbreviated in mass produced rotors. This results in restraining heat distortion, and improves fade resistance. Other remarkable features are as follows: function to let out fade gas generated from heated brake pad, or cleaning slit that planes the surface of carbonized brake pad and enhances brake operation.
