AutoExe original setting. Mechanical type with best street specifications.
The mechanical (multi-plate clutch) limited slip differential distributes and transmits effective traction to the left and right drive wheels when cornering or on slippery surfaces, and is based on the proven Cusco product, with AutoExe's original settings designed for ease of use and comfort.
The 1.5-way operation method is 100% effective when the accelerator is on and 50% effective when the accelerator is off. The drive cam angle is set to 35-45°, and the torque bias ratio is set to 4.0-6.0 on the drive side. The initial torque is set to 40.8-51.0Nm, providing a direct operating feel and reliable traction. This item accentuates the handling characteristic of FR vehicles. Also, with street driving in mind, the specifications minimize chattering (the metallic sound that occurs when the clutch plates slip). The product comes with the specified LSD oil.
Below is an overview of the "aims" and "technology." Because differentials are a black box for most readers, it may be difficult to imagine how they work, but if you're thinking about tuning a differential, it's best to at least understand the basic principles. This is because the usability can change significantly depending on the design intent.
First, some basic knowledge: a differential is a device that changes the rotational speed of the inner and outer driven wheels when a vehicle turns. This is because, when turning at a fixed angle as shown in the diagram, the radius of the path traced by the inner and outer wheels is different. Naturally, the outer wheel must travel a longer distance than the inner wheel, and must rotate faster. Otherwise (if they rotate at the same speed), the inner wheel will slip and consume excessive rotation, preventing smooth turning. In short, a differential is a mechanism that creates a difference in rotation between the driving wheels. That's why it is also translated as a "differential device" in Japanese.
Of course, there is no need for differential when going straight, and differential is not good either. If there is a difference in rotation between the drive wheels, it will change the direction of travel. So how does the differential know when it's time to turn? The basis for this judgment is resistance from the road surface.
