More than mass production, less than tuning.An update program for out-of-print sports cars.
In the early 90's, when the bubble economy did not cool down, the flagship of a large displacement 6-cylinder engine armed with a turbo competed for high power, and a full-time 4WD homologation model that seemed to escape from the competition venue ran around the city.Japanese car makers were competing with high technology, and car lovers in the world enjoyed the golden age of sports machines.

It was our Mazda RX-7 (FD) and Roadster (NA) that purely pursued the enjoyment of driving a car in such an era.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 ultimate in Jinba Ittai that cannot be obtained with a passenger car.It is a stoic design concept even in light of the standards of the time, such as a tight cockpit that is hard to say comfortable and a steering that is completely fixed without any tilt or telescopic mechanism.Many people continue to be fascinated by the solid handling that is not found in modern cars, which are equipped with a skid suppression mechanism and a driving support system as standard equipment.
However, it is unavoidable that the running will fade over time.Together with the owner who has been close to his car for many years or has acquired a new feeling of the past, we at AutoExe also want to clearly bring out the charm of the cars of that era!That's why we are now tuning for out-of-print sports cars.

As you know, our consistent concept is street vest.In order to pass on the originality of mass-produced cars to the present age, we will make the latest updates to key points and pursue "Kansei tuning".The items are a stainless muffler with polished exhaust efficiency and a comfortable sports sound, and a headlamp kit converted to LED projector specifications.And we have set up a special menu such as a mass-produced suspension kit, which is the highlight of the ride.Regular menus such as intakes, brakes, and drive trains are also substantial.The program was initially planned for limited-time production by the end of 2019.However, in order to respond to the hot love call from the enthusiast who loves both models, he decided to continue production and backed up his active life. "More than mass production, less than tuning", our FD & NA update program.I want to go on the path of evolution with you.

Street suspension kit

The aim is to restore pure sports and further enhance Jinba Ittai.
The mass-produced suspension kit, which is the highlight of the program, has undergone our own "Kansei tuning" in order to inherit the concept at the time of the release of both models to the present age.In the actual setting, the specifications are synchronized with the sensibility of the owner who wants to enjoy driving more by analyzing the transient characteristics at the moment when the car moves.In the nostalgia, I am proud that it was finished with a ride that adds the accuracy of the current style and the feeling of flat riding.The product is an assembly specification that incorporates a genuine upper mount / bump stopper into the original damper and spring.The details, development story, and comparison with mass production specifications are summarized in the spec sheet.If you attach it to your car ... I want you to imagine a sophisticated cornering scene in your mind.

Brake parts

To the effect synchronized with the sensibility, which goes beyond the ability to simply stop.
The first performance required for brakes is safety that can be stopped reliably.However, the ideal brakes for sports-oriented drivers, such as delicate load transfer during cornering and flexible control of vehicle speed, are not ON / OFF like a switch, or they do not work hard with emphasis on initial braking. , The performance that the required braking force can be obtained naturally and accurately, that is, the "effect that synchronizes with the sensibility" that slows down at will.To achieve the street vest, we at AutoExe are also sticking to the sensitivity tuning of the brake system.The lineup of this update program includes the roadster (NA6CE) in addition to the well-established street sports brake pads and street brake rotors. With the mainstream grade not equipped with ABS, we are assured that you can enjoy the desired effect purely.
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
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

Fine tuning rebuilt engine

To an ultra-smooth feeling that goes beyond mass production.
Handmade RE assembled with high precision.
A high-precision handmade rebuilt engine that achieves an ultra-smooth rotation feel that surpasses that of mass-produced engines.When assembling, take advantage of one-item production and thoroughly control the clearance of each part to 1/100 mm or less.The latest genuine Mazda parts are used for all replacement parts, and the reused parts are also rigorously measured and modified.The effect of the tuning is not only the improvement of output but also the acquisition of ultra-smooth rotation feel and response with stability and quietness.So to speak, it is finished in an RE-like engine that exceeds mass production.Furthermore, for the RX-7, the stepped correction of the exhaust port, which is directly linked to the performance difference, was made to improve the instantaneous power of the RE turbo. * A trade-in engine without modification is required at the time of purchase.
