Look at this table, please choose your optimal LSD depending on the budget and preferences and use.

Except for the drag race, in all of racing and street use, we strongly recommend the hybrid type of carbon LSD.
This hybrid, carbon LSD was able to increase the durability. In addition, type DD of LSD have dramatically increased the durability of the ATS LSD.
Carbon LSD has caused the market claims in 2006. However, product since 2007 by the improvement is in popular selling without complaint.

Carbon LSD has a miracle performance that does not cause the understeer. This is the proof that the necessary minimum of a limited slip differential. Since there is no understeer, you will be able to increase the acceleration time. By the same principle as the features of the above, you will be more safe driving in the wet road surface.Metal LSD has a huge differential lock power by the friction characteristics. Carbon LSD is, with a minimum of order to run fast the car, and will have a strong enough differential lock power. This is due to the friction characteristics of the ATS made of carbon.

LSD having such friction characteristics, only ATS in the world manufactures and sells. Type of LSD to limit the opening and closing of the cam in the coil spring that recently has increased in the market, can not be accurately accelerator control the LSD. ATS is not to develop these types of LSD is due to the fact that they avoid this drawback. This disadvantage, gives anxiety to the driver. In such a LSD, it does not win possibly the carbon LSD-equipped vehicles.

Carbon Hybrid

Carbon hybrid LSD is LSD with increased durability with a partially metal plate in place of the carbon plate. Performance will not be able to distinguish between the carbon LSD. To prevent wear and tear of the carbon chip by contacting the cam the metal instead of carbon. As a result, even the smaller reduction in the initial torque. Setting of high initial torque is also available.

If you further increase the metal plate, it will replace the carbon plate and the metal plate from the cam ring surface toward the outside. Metal plate and carbon plate, and arranged so as to be symmetrical with respect to the cross shaft. Since the metal plate and carbon plate there is a difference in thickness, and adjust the difference in the thickness change of the spacer and the disk spring.

Initial torque is determined by the built-in number of cone spring. Initial torque will be adjusted in the range of 15 ~ 20kgm. Front LSD of FF vehicles and Lancer Impreza is a carbon hybrid LSD is the best choice.

Price of carbon hybrid will drop significantly to carbon LSD. For example, the retail price drops 10,000 yen by changing the two carbon into two metal.

(please note)  Please to measure manage the oil temperature. Please cooled the LSD oil from when the oil temperature exceeds 140 degrees Celsius. Carbon tip is more likely to peel off from the steel plate when you continue to use the carbon LSD at a high temperature.

Carbon LSD Spec1

SPEC1 the initial torque at the time of shipment is 8 ~ 10kgm. Unlike metal LSD, carbon LSD can differential lock in the initial torque 1kgm. So silence and soft rock feeling, you will not be able to feel the presence of carbon LSD. However, you can experience a linear rock performance with very sense of stability at the moment of attack the corner. Since the feeling at the time of a new article is long-lasting, rarely feel the need of overhaul in the use of the street. It does not cause as many of the changes in the occurrence and rock feeling of abnormal noise has been adapted to the oil stocks.

The FR car of high-power ultra-light type lap times within one minute of the Tsukuba circuit, there are many examples of SPEC1 is used in order to avoid understeer. In addition, in the short-circuit, the measures of the missing drive by in-lift in such as riding the curb is required. For the purpose of this measure is essential for a good suspension of the follow-up. Optimal LSD in FF cars and 4WD vehicles front LSD is a carbon hybrid LSD instead SPEC1. The next to it is recommended SPEC4 / SPEC5 of carbon LSD.

(please note) Please to measure manage the oil temperature. Please cooled the LSD oil from when the oil temperature exceeds 140 degrees Celsius. Carbon tip is more likely to peel off from the steel plate when you continue to use the carbon LSD at a high temperature.





Carbon LSD Spec3

SPEC1 the initial torque at the time of shipment is 8 ~ 10kgm. Unlike metal LSD, carbon LSD can differential lock in the initial torque 1kg · m. So silence and soft rock feeling, you will not be able to feel the presence of carbon LSD. However, you can experience a linear rock performance with very sense of stability at the moment of attack the corner. Since the feeling at the time of a new article is long-lasting, rarely feel the need of overhaul in the use of the street. It does not cause as many of the changes in the occurrence and rock feeling of abnormal noise has been adapted to the oil stocks.

The FR car of high-power ultra-light type lap times within one minute of the Tsukuba circuit, there are many examples of SPEC1 is used in order to avoid understeer. In addition, in the short-circuit, the measures of the missing drive by in-lift in such as riding the curb is required. For the purpose of this measure is essential for a good suspension of the follow-up. Optimal LSD in FF cars and 4WD vehicles front LSD is a carbon hybrid LSD instead SPEC1. The next to it is recommended SPEC4 / SPEC5 of carbon LSD.

(please note) Please to measure manage the oil temperature. Please cooled the LSD oil from when the oil temperature exceeds 140 degrees Celsius. Carbon tip is more likely to peel off from the steel plate when you continue to use the carbon LSD at a high temperature.

Carbon LSD Spec4

SPEC4 is the standard specification of carbon LSD.SPEC4 you add two cone spring to SPEC3 is, initial torque at the time of shipment is 20kg · m. In the race, the competition Street, is the ultimate LSD that can be intoxicated by the speed and rock feeling. Silent performance, natural handling, wet performance, etc., gives a high satisfaction to the driver even in urban areas is also on the track.

Consider how to accelerate how quickly in the corner for the time up, you need try for opening the accelerator from clipping point forward. "DEEP BLUE" of ATS of LSD oil for the oil temperature measures, to strengthen the lock is recommended ATS LSD oil "Hard-Locker." High initial torque is in the agility of the communications-operation between the driver and the vehicle, this thing will lead to victory by accumulating time in hundredths of a second. The regulation in order to maintain a high initial torque, please deal with it to add a shim plate with a thickness of 0.2mm of ATS.

(please note) Please to measure manage the oil temperature. Please cooled the LSD oil from when the oil temperature exceeds 140℃. Carbon tip is more likely to peel off from the steel plate when you continue to use the carbon LSD at a high temperature.


Carbon LSD Spec5

SPEC5 is, the clutch plate is an increase of four to SPEC4, cone plate is using two. Initial torque at the time of shipment is 20kgm. It is the strongest model of carbon LSD. Wonderful properties of the carbon LSD in the same manner as the SPEC4 are equipped with all. SPEC5 because not only can be installed in a large vehicle LSD case, the lineup is only 5 and 6 models. As for FF vehicles, there is a SPEC5 for "HONDA-FD2, DC5, DC2, EK9" "SUZUKI-ZC32S". As for the FR vehicle there is "MAZDA ND5RC" "Quick Change LSD".

SPEC5 was developed for quick change 10inch of Winters, Inc. (USA) and the SpeedWay, Inc. (USA). In Time Attack department of the 2013 Pikes Peak (total length 20km), Darren Bach won equipped with SPEC5 to quick change.This LSD is being quite useful in the D1 series and FD series of drift.

(please note) Please to measure manage the oil temperature. Please cooled the LSD oil from when the oil temperature exceeds 140 degrees Celsius. Carbon tip is more likely to peel off from the steel plate when you continue to use the carbon LSD at a high temperature.

Metal LSD

Metal LSD has sharply powerful differential lock performance. Since FF car has no power oversteer, metal LSD is particularly effective in the FF vehicle.FR vehicle, you must have the oversteer measures at the corner exit. It is measures by car settings and driving. Understeer measures at the corner entrance, is possible by the selection of 1way and 1.5way cam.

Compared to carbon LSD, metal LSD is inferior in the lap time and noise. However, to the oil temperature management may be a rough than the carbon LSD, it is inexpensive. In order to avoid the abnormal noise, you must be careful in the selection of LSD oil.







Carbon LSD Spec1

Silent LSD is, new clutch plate with reduced significantly abnormal noise, has adopted a 45-degree and 55-degree or 60-degree cam. Standard specification, use the 45 degrees of cam start of the differential lock is slow, we are arranging the clutch plate so that the lower the differential lock force. Abnormal noise will disappear in the run-running of this for about 20km.

Although the silent LSD, abnormal noise is generated by wrong selection of LSD oil. Standard specification is the most abnormal noise occurs less specification. Standard specification of 74mm type of metal LSD is silent LSD. When ordering a race specification, please be presented with the "strongest specification".
