AutoExe original settings. Mechanically designed for street performance.
The mechanical (multi-plate clutch) limited-slip differential, which effectively distributes and transmits traction to the left and right drive wheels during cornering or on slippery surfaces, is based on a proven CUSCO design and features AutoExe's original settings that prioritize ease of use and comfort.
The operating system is a 1.5-way type, with 100% engagement when the accelerator is on and 50% when the accelerator is off. The drive-side 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 40.8-51.0 Nm, achieving a direct operating feel and reliable traction. This item enhances the handling characteristic of FR vehicles. Furthermore, with street driving in mind, the specifications have been designed to minimize chatter (the metallic sound when the clutch plates slip). The product comes with specified LSD oil.
The following is an overview of its "purpose" and "technology." Since the differential is a black box for most readers, its mechanism may be difficult to visualize. However, if you are considering tuning your differential, it's best to understand at least the basic principles. This is because the usability changes significantly depending on the design intent.
First, some basic knowledge: a differential is a mechanism used to change the rotational speed of the outer and inner wheels when a vehicle turns. This is because, as shown in the diagram, when turning at a certain angle, the radii of the trajectories traced by the inner and outer wheels are different. Naturally, the outer wheel must travel a longer distance than the inner wheel and therefore needs to rotate faster. Otherwise (if they rotated at the same speed), the inner wheel would slip and waste excessive rotation, preventing smooth turning. In short, a differential is a mechanism that creates a difference in rotation between the drive wheels. That's why it's translated as "differential device" in Japanese.
Of course, there is no need for differential action when driving straight, and differential action would be problematic. If there is a difference in rotation between the drive wheels, the direction of travel will change. So how does the differential recognize when it is "turning"? The basis for this judgment is the resistance from the road surface.
