Why the Limited slip differential is a must have? Especially for RWD cars!
How does a limited-slip diff work?
The limited-slip differential offers more control over power distribution than a conventional 'open' diff. An open diff uses gears to ensure that the wheels turn at different speeds when going round corners, but it can easily it become overpowered. When the power arrives at the wheels, it looks for the path of least resistance, which in this instance means the tyre with the least amount of grip. If you're heavy with the throttle, and have a powerful engine, this means that all the power may be lost in a cloud of smoke as the unloaded tyre spins away, while the other tyre continues to grip.
In contrast, an LSD and extra mechanisms (a clutch assembly, cams, or even a viscous fluid system that's part of the diff) counter this natural flow of power to re-distribute the engine's torque to the wheels with the most grip. The result is reduced wheelspin for the unloaded tyre, and the engine's power is put to the road more effectively, which will boost grip, and therefore, cornering and acceleration.
There are many types of LSDs: Viscous, Helical, Clutch-type. We consider the clutch-type as the most efficient with the best performance. In addition, it’s the only one that can be adjusted according to your performance.
