New release for MAZDA3/CX-30.
Manipulate MT directly and quickly.
Shift kit for short stroke specifications.
Two pedals are now the mainstream even in super sports models.The superiority of AT is undeniable not only in terms of easy driving, but also in the speed and accuracy of shift changes.If you want to enjoy changing gears in a primitive manual transmission car, you want to pay close attention to the shift feel.What we focused on was the short stroke of the shift mechanism that connects the shift knob and transmission.Although the mechanisms of the vertical transmission Roadster and the horizontal transmission MAZDA2/CX-3 are completely different, we carefully examined the lever ratio and inertia weight.It's neither too heavy nor too light, and has been tuned to feel like the palm of your hand is directly connected to the drivetrain.Furthermore, when installed simultaneously with an AutoExe shift knob with adjustment functions, it is possible to finely adjust the shift stroke.If you change gears while imagining the operating concept, you are guaranteed to enjoy driving intelligently.
[For MAZDA3/CX-30]
By changing the lever ratio of the shift select arm on the transaxle inside the engine room, the stroke has been shortened.Depending on the driver's preference, the stroke can be adjusted to a total of 13 levels, ranging from 41% to 3% compared to mass production.Furthermore, the moment of inertia is optimized by adjusting the weight balance, and the shift feel is sensitively tuned.In addition, the rigidity-enhancing effect of replacing the mass-produced rubber bushing with a rigid mount for the interior shift lever pedestal joint cannot be overlooked.
[Product configuration]
Kit consists of a 3-stage adjustable shift select arm, weight block, holder link/bush, etc.
Recommended for use with mass-produced shift knob or AutoExe shift knob.
[Comparison of shift strokes】
Compare the amount of forward / backward movement from 1st gear to 2nd gear with mass-produced products.
■ Mass production: Approximately 98 mm
■Made by AutoExe: Approximately 58-85mm
* Movement amount at the center of the shift knob
By changing the hole position of the shift select arm, it is possible to shorten the stroke in 3 stages (AutoExe recommended value -28%). (■The figures in the table below are approximate numbers. )
| hole position | Stroke amount | Mass production ratio |
|---|---|---|
| 1 stage | XNUM X mm | -13% |
| 2 stage | XNUM X mm | -28% |
| 3 stage | XNUM X mm | -41% |
| Mass production | XNUM X mm | - |
[Balance weight adjustment mechanism]
The weight of the arm center part is adjusted according to the stroke amount to optimize the moment of inertia.
[Rigid mount on pedestal]
The shift lever pedestal fastening part has been changed from a mass-produced rubber bush to a rigid mount to increase rigidity.
【Diagram】
The shift select arm on the transmission side, which connects to the indoor shift lever, has a short stroke.
[For Roadster (ND series)]
The mass-produced version has a clever design with a built-in leaf spring and urethane bushing in the shift lever to absorb shift shock and vibration.Although it is a sports car, it is designed with consideration to ease of handling and comfort for the average driver.We pursued a sense of moderation by eliminating leaf springs and urethane bushings.By changing the lever ratio, the stroke has been shortened by approximately 24%.
[Product configuration]
Kit consists of SUS304 shift lever, spacer, mounting bolts, and liquid gasket.
Recommended for use with mass-produced shift knob or AutoExe shift knob.
[Comparison of shift strokes】
Compare the amount of forward / backward movement from 1st gear to 2nd gear with mass-produced products.
■ Mass production: Approximately 81 mm
■ Made by AutoExe: Approximately 62 mm
* Movement amount at the center of the shift knob
By changing the lever ratio by moving the fulcrum, a short stroke of 24% compared to mass production has been achieved.Furthermore, when the shift knob made by AutoExe is used together, the shift stroke can be changed by the full length adjustment mechanism. ((■The figures in the table below are approximate numbers. )
| Length | Stroke | |
|---|---|---|
| With spacer | +11 mm ~ -6 mm | 66 mm to 60 mm |
| No spacer | +3 mm ~ -11 mm | 63 mm to 58 mm |
[Direct operation feeling]
Eliminates "leaf springs" and "resin guides" to alleviate shift shocks installed in mass-produced products.Achieves a direct shift feel with little play.
[Further shorting is possible]
When installing the AutoExe shift knob, you can further shorten the stroke by removing the attached spacer.■When the mass production shift knob is installed, it cannot be used by removing the spacer due to its structure.
[Example of installing AutoExe shift knob]
The overall length is the same as the mass-produced product due to the shorter stroke by changing the lever ratio.There is no change in appearance when mounted.
