The concept is "More than mass production, less than tuning ".
An update program for the first NA, a timeless Jinba Ittai.
Weight distribution of 50:50 front and rear to FR layout of lightweight body.And the four-wheel double wishbone suspension ... The feeling of manipulating the steering and turning around the driver can be said to be the pleasure of pure lightweight sports.For the first NA Roadster, we insist on further enhancement of the "human-horse sense of unity" that is faithful to the original concept ... The item is a stainless muffler with polished exhaust efficiency and a comfortable sports sound, LED projector specifications. Headlamp kit converted to.And the mass-produced suspension kit, which is the highlight of the ride.We have developed an update program to pass on the existence of only one to the present age, and continue to back up the active duty throughout our lives.
Functional parts
■ Street suspension kit
Specifications that analyze the transient characteristics of the moment when the car moves and tune in to the sensibility of the owner who wants to enjoy driving more.In the nostalgia, we finished it with a ride that adds modern accuracy and a flat ride feeling.
<Main specifications> Mass production shape Twin tube Damping force fixed type damper + Mass production shape spring
Assembly product with built-in genuine upper mount and bump stopper for NB
Spring constant Fr: 36.3N / mm (mass production ratio 133%) Rr: 23.3N / mm (mass production ratio 142%)
Vehicle height down amount: -15mm compared to mass production
■ Ram air intake system
It consists of a large-capacity cleaner box with a specially designed intake path and a low-resistance K & N wet air filter that can be cleaned with the included maintenance kit.The shape of the carbon air box and the intake duct protruding from the top of the bonnet provide powerful acceleration from the moment you start stepping on the accelerator.The appearance made of real carbon is also high quality.>> More details
<Main specifications>・Special wet filter + carbon duct
■ Stainless muffler
Special specifications with a clean straight cut φ70 tail.A large-capacity straight structure silencer with low exhaust resistance and excellent response, a modest φ50.8 intermediate pipe, etc. create a well-balanced output characteristic and a gentle sports sound. Can be installed on all NA roadsters.
<Main specifications> ・ Pipe diameter: Φ50.8 ・ Tail diameter: Φ70 ・ Stainless steel
Update PROGRAM site■ Exhaust manifold
The basic design is a 4-2-1 layout aimed at increasing torque from medium and low speeds. The assembly part of 4 or 2 pieces is made longer than mass production, and the angle of the confluence part is narrowed to prevent the blow-down phenomenon (exhaust backflow) that occurs at high rotation speed.In addition, a radial shape was adopted for the joint to the first part to increase the exhaust flow velocity.As a result, the torque (power) is improved from low to medium speed to peak. >> More details
Main specifications> ・ Specifications: Made of SUS304 stainless steel ・ Pipe diameter: P = Φ42.6 T = Φ54.0 ・ Safety standard compliant product ・ Made by Maxim Works
■ Sports plug cord
Uses a stainless steel core wire with low electrical resistance and excellent noise resistance.By wrapping the core wire around the reinforced Kevlar and winding the three Kevlars in a spiral shape, the generation of the magnetic field that causes noise was prevented.Furthermore, the core wire is coated with a double silicone film.As a result, it achieves both low resistance of about 3Ω / m (ignition power is about 2 times that of mass production) and noise countermeasures that are a concern due to the low resistance.>> More details
<Main specifications> -Uses low resistance triple structure core wire
■ Street sports brake pads
The aim is "deceleration at will".Designed with an emphasis on stable effectiveness during continuous braking, delicate load transfer in cornering, and flexible control of vehicle speed, rather than simply stopping performance.Focus on the amount of change and how to change the coefficient of friction (μ), which constantly changes depending on various conditions such as pedaling force, speed, and temperature.The "transient characteristics of μ" required by sports-oriented drivers realizes a taste that is synchronized with the sensibilities.>> More details
<Main specifications> ・ Non-asbestos friction material ・ Rotor proper temperature: 0 to 400 ℃
■ Club sports brake pads
Sometimes to the circuit ...A sports pad that aims for "deceleration at will" that synchronizes with the driver's sensibility in high load areas such as continuous corners and full braking from straight.The material is a blend of carbon and a metal material with excellent fade resistance.It balances the conflicting frictional force and the suppression of rotor aggression at a high level. >> More details
<Main specifications> ・ Graphite metal friction material ・ Rotor proper temperature: 50-800 ℃
■ Street brake rotor
Mass-produced XNUMX-piece structure with the same shape FC Cast iron, but with improved strength by controlling the content of carbon and silicon.Further heat treatment is applied to stabilize the metal connective tissue.It suppresses distortion due to heat and improves fade resistance and crack resistance. >> More details
<Main specifications> ・ 6 slits on one side, 1 piece type
■ Sports clutch set
The facing material is a non-asbestos material that exhibits high mu in a wide temperature range.In combination with a doug tile cast iron cover with a crimping force increased by about XNUMX% compared to mass production, reliable torque transmission is possible.Although it requires some pedaling force for operation, it is a characteristic that is easy to handle in sports driving because the meet point at half-clutch is clear compared to mass production.>> More details
<Main specifications> ・ Genuine shape non-asbestos specifications ・ Crimping force: 5.2kN (1600) ・ 5.9kN (1800)
■ Sports clutch line
Uses stainless mesh PTFE (Teflon), which has less deterioration due to heat and aging and less expansion due to hydraulic pressure than the rubber used in mass-produced vehicles.Contributes to a direct clutch feel.In addition, PVC coating is applied to guard the hose for safety.It is a part that I would like to recommend even when installing a reinforced clutch that puts a burden on the clutch line. >> More details
<Main specifications> -Stainless steel mesh PTFE + PVC coating)
■ Limited slip differential
The mechanical (multi-plate clutch) limited slip differential, which distributes and transmits effective traction to the left and right drive wheels when cornering or on slippery roads, is based on the proven CUSCO product and is easy to use and comfortable. The original setting was applied.The operating method is 1.5 Way.Compared to mass-produced products, the direct operation feel is attractive.>> More details
<Main specifications> -Mechanical 1.5way cam angle 35 °-Torque bias ratio: 4.0-6.0-Specified LSD oil is included.)
■ Oil filler cap
The oil filler cap has been changed from genuine resin to 52S aluminum, which is fully machined and full of craftsmanship.Brilliant red alumite processing is applied to give a mechanical and gorgeous accent to the engine room.The laser-engraved AutoExe logo is also a delicate impression. >> More details
<Main specifications> ・ 52S aluminum fully machined ・ Red alumite processing ・ Laser engraved with AutoExe logo
■ Aero sports wiper blade
An aero type wiper blade is used for the main body.By adding a deflector with fins, the arm joint is aero-formed.The wind pressure generated during driving is positively received and the wiper lift is suppressed.The blade rubber is evenly adhered to the glass surface to improve visibility when driving at high speeds in the rain. >> More details
<Main specifications> ・ Driver side: 450mm ・ Passenger seat side: 450mm ・ Twin rail type
■ LED headlamp kit
A kit for replacing the assembly of a mass-produced sealed beam headlamp unit.High beam, low beam, and daylight are all LED (5 chips in total).The combination of an optic lens that diffuses light and a reflector realizes ideal irradiation.
