By utilizing the CC composite disks, the ATS carbon LSD posses the superior transitional characteristics from free to differential lock, enabling control that feels quite natural.

The Carbon LSD type Street is designed for street driving with only 4 internal disks. For a competitions which push the vehicle to the limit, please choose the standard ATS Carbon LSD.

Principal characteristics of the Carbon LSD

* Gentle transitional characteristics that yield ease of handling from free to lock
* Small degree of slipping which provide a greater flexibility
* Super durable
* Stable differntial lock performance which is unaffected by oil temperature changes
* Quiet operation without chattering noise
* The performace of carbon LSD is not infulenced by a choice of LSD oil
* Very high adaptability to many LSD oils from different manufacturers

An inevitable drawback of a clutch type LSD has been the undesirable chattering noise. Even though the performance advantage of a clutch type LSD are well documented, many people have resorted to a "gear type" or "viscous type" LSD to avoid the noise during daily street driving. You no longer have to make that trade off!! The new ATS Super Silent LSD offers the best of the both worlds, the performance of clutch type LSD and the quietness of a gear type LSD.

By completely redesigning the internal plates, from material to the grinding and by utilizing a new cam angle, ATS has successfully eliminated the chattering noise without negatively impacting the excellent locking performance you desire. The new SS LSD provides the driver a very comfortable and smooth ride during street driving and exceptional traction when needed.

ATS SS LSD comes with a cam ring with both 45 degree and 60 degree (or 55 degree in the case of 87 mm & 82mm diameter plates) cam angles. The cam angle is set at 45 degrees at the factory unless it is specified at the time of ordering but the cam angle can be easily changed by your mechanic.

The drift category features increasingly high-level competition and so the evaluation criteria are also becoming increasingly rigorous. The LSD's potential to skillfully control and vehicle plays a decisive role in the high-power and weight-reduction specifications.

Deftforec is a dedicated, reinforced LSD that was developed by taking into consideration loads obtained during drifting when an LSD is subjected to its severest use conditions, and by reviewing all performance using the competition data from D1 drivers. As is to be expected, durability is of greatest concern of the LSD, which is abused frequently in both preliminary and final races. After extended use in drifting competition, the conventional LSDs wear out in several months. Even during excessive use, ATS Deftforce ensures 1 to 2 years of long-life performance with simple regular replacement of the differential oil. In addition to the super durability and powerfull locking performance, it also provides outstanding controllability.

Principal characteristics of the Deftforce
* Power and toughness from a non-grinding clutch plate with the world's largest diameter
* Five times the durability of conventional models
* Optimization of performance based on technical feedback from D1 Grand Prix drivers
* Controllability that enables the control of vehicle angle and travel distance

In the racing world where winning is everything, excellence without compromise is required for all components. The differential is certainly not an exception to this requirement when it comes to part selection and setup. Performance and reliability are paramount in the single-minded pursuit of victory. The ATS LSD supports this requirement in many ways, with its high quality and high performance based on considerable race data accumulated over many years. ATS LSD is for drivers who demand the outstanding features and the powerful locking performance of a metal LSD. Their focus on quality will steer them directly to victory.

Principal characteristics of the metal LSD
* Uses a non-grinding clutch plate that features high lubrication performance and tough surface hardness
* Equipped with a maximum-diameter clutch plate that enhances locking performance
* Stabilizes accelerating response by applying the appropriate initial torque
* Quick transitional characteristics from free rotation to lock - indispensable for drag racing & drifting
