■Differential lock force less than 1 / 10th of metal LSD
The locking power of the ATS carbon LSD is very strong as perceived, but actually it is less than 1 / 10th of the metal LSD. The differential locking force of the metal LSD is much stronger than the tire grip force and the possible maximum force is larger than the strength of the drive shaft and of the internal gears of the LSD. In order to avoid the harmful effects of the very strong differential lock, the other manufactures set the cam angle and the initial torque of a metal LSD significantly reduced with a result of slowed down throttle response. But since carbon LSD does not have the excessive lock force problem, it can bring out the full potential of the driver by responding to the driver’s input directly and quickly with a high initial torque and with an optimum cam angel.

■Resist persistently to a sudden differential slip
Although the metal LSD has a very strong differential locking force, a large slip could occur suddenly due to changes in the road surface condition and in throttle operation. This is due to the extremely large difference between the maximum static friction coefficient and the dynamic friction coefficient of the metal plates in the LSD oil. Since ATS carbon LSD has small difference between maximum static friction and dynamic friction, it resists slipping continuously.
■LSD locking force vs the tire gripping force
The locking force of the ATS carbon LSD is smaller than the tire grip on the dry road surface and is close to the tire gripping force on the wet road surface. For this reason, on a dry road surface, a carbon LSD does not disturb the handling even during acceleration. Moreover, it is easy to find grip and enjoy the LSD’s performance on wet road surface due to its controllability of the throttle response.
■The Best and Ideal LSD
The differential locking force value close to the that of tire gripping force and the sticky friction characteristics of carbon eliminate most instability factors caused by differential movement. For this reason, the carbon LSD not only can provide a very fast lap in races and competitions, it also demonstrates an excellent stability in driving stability on a highway in a rainy weather. Moreover, even with a very high initial torque for an outstanding throttle response, it is super quiet and you even do not feel the existence of LSD on the street.
