NB-04

A “Jinba Ittai” feeling , more strongly
Up to date, complete facelift for NB

The buoyant ROADSTER (NB), strongly inheriting the blood of the first generation of NA, now is installed with cutting edge features with an up to date appearance as NB-04. The sophistication is upgraded while preserving the traditional sports feeling that does not fade away even in the modern standards.
‘More AutoExe like, more gracefully’ ? ? ? getting a hint from the exquisitely-chiseled sports appearances of all models of the 04 series, the front nose represents modern-style intrepidness and cleanliness. As for functional parts, the Street Sports SUS.Kit and the non-slip differential go together with direct feeling and flexibility. A two-piece type of sports brake rotor boosts up its special feature — which is brisk handling.
Moreover, even voluptuous sound, generated by the sports induction box and the premium tail muffler, pumps up the open-air motoring. A meticulous, refreshing menu to continue to love a human-like ROADSTER. Running united with a horse is hotter and more profound than ever.

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(KIJIMA-SPEC)
Height adjustable kit boosts a sporty ride, while maintaining a balance of mass production specifications. Based on the theory of the engineering dynamics of driving sensation, developed by Mr. Takao Kijima, who is an authority on suspension and the Chief Engineer in sports car development at Mazda, vehicle height, spring rate, and damping force have been well established. It is tuned for exquisite handling beyond the constraints of mass produced vehicles. Mr. Kijima himself directly inspects KIJIMA-SPEC for the FR sports-car. Twin-tube dampers with high precision.

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 (Front)
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.

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

 

■Sports Induction Box
Only the part of the genuine air cleaner cover that is of air intake resistance gets removed. Air intake efficiency is then improved by using the induction box with a genuine air cleaner element. The product sucks in fresh air and is comprised of an aluminum baffle plate that provides a thermal protection from the engine room and a funnel type FRP frame mounted in front of the filter. Efficiency can be further enhanced by combining it with an optional air cleaner. The sporty engine sound that results from removing the air cleaner cover also heightens its appeal.

■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.

■Exhaust Manifold
It is the isometric 4-2-1 type that can aim at an increase of torque from the low and the high-speed area.  The pipe diameter and the layout for smooth emission of exhaust gas are carefully selected to realize an increase of power in the entire area.  The glossy pipe of stainless and the fully machined flange are well worth seeing, too.  It not only is installed, but also is a hallmark with peculiar tastes that gives you the feeling of satisfaction.

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.

■Sports Brake Rotor
Our Sports Brake Rotor has a full two-piece structure that improves fade and crack resistance. Specifications in pursuit of functionality include the fin shaped ventilation that steadily releases heat, the cleaning slits that help maintain the pad surface in good condition, and the black finish that protects the rotor from rusting. The bell housing is made from lightweight duralumin. Only the disk rotor part needs to be replaced once the product has worn-out. Designated a sports car lineup product.

■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.

■Sports Brake Line
If you jam down on the brake pedal, the pressure is conveyed to the pad through the hose containing the brake fluid to actuate the brake.  The hose material is changed from genuine rubber to Teflon coated with low-expansion stainless mesh to convey the force on pedal efficiently to the pad, and improve the braking reaction.

Drivetrain Parts

Pull the potential of the engine completely out and convert it into traction on the road surface. A sports clutch set and a flywheel to support brisk gear change. While increasing the feeling of being directly connected with the car, Limited Slip Diff, for example, the driver positively enjoys the change of the attitude of the car in turning a corner, and the transient characteristic, where abrupt movements are eliminated as much as possible, are built in.

Parts lineup

■Sports Plug Cord
The ignition electric power of spark plug is enhanced as much as 20 to 30 times by wrapping the stainless core around the Kevlar tempered fiberglass so that the power and the fuel consumption can be improved.  For the noise of the radio that tends to be generated when the resistance is lowered, the proper measures are taken by the core wrapped around in a spiral manner for containment with twofold silicone.

■Sports Clutch Set
Optimum mass production models for street driving. Non-asbestos materials that exhibit a high μ in a wide temperature range are used as the facing materials. In combination with ductile cast iron pressure plate with an approximately 30 % mass ratio pressure-bonding force increase, it allows reliable torque transmission. Manipulation may require slight breaking actions, but the meeting point of the clutch is easer to capture than for the mass produced cars.

■Sports Clutch Line
The stainless steel mesh PTFE (Teflon) clutch line creates extremely small expansion generated by oil pressure, and very little degradation due to lapse of time compared to rubber clutch line which is used in mass-produced vehicles. The feeling of the clutch is more direct and lasts for a long time. In addition, a PVC coating is applied to protect the hose.

■Limited Slip Diff.
A mechanical (multi-plate clutch) non-slip differential which distributes and transmits effectively to the left and right drive wheels on slippery surfaces or when cornering, is treated with the AutoExe original setting that cares for convenience and comfort based on proven CUSCO.
Operated with a 1.5 way differential. By setting the cam angle at 45° on the driver side, the drive torque bias ratio can be set to 4.0 to 6.0. Initial torque is set up at 40.8 N-m, which minimizes the chattering. Feeling the grip directly, and reliable traction are appealing compared to the mass production models.
