LSD - Limited Slip Differential

• For Honda FF (1.5-way) and Honda S2000 (2-way and 1.5-way)
• Developed using an enormous amount of data from actual races (endurance, sprint & drag races)
• The definitive locking power. Feel the traction while cornering.
• Excellent durability
• Superb controllability

ATS Carbon LSD    (New)
Developed for Formula Nippon. Absolute minimum mechanical noise and superb maintenance of initial torque. Used for Formula Nippon since this season. Available for S2000 .

The release of Carbon LSD for Integra & Civic has been postponed.

Carbon composite LSD development background
          Formula Nippon - the ultimate battle ground for the Japanese formula car racing. The LSD for formula cars requires the highest standard. Effectiveness, durability, and controllability - in every respect it has to be the best. In addition, due to the dry sump method used for formula car, LSD operates with only tiny scattered oil particles. A normal iron plates cannot achieve its objectives in the race under these conditions.
          ATS took this challenge and finally after long research and development has released its carbon LSD for formula racing this season (2001). A higher friction coefficient and heat resistance of ATS carbon composite disk leads to the revolutionary performance. ATS' carbon LSD maintains its initial torque setting and locking ratio under the severest formula car racing condition.
          Applied this technology beyond formula car racing, ATS carbon LSD bring you unparalleled durability and maintenance of initial torque under any driving condition without mechanical noise usually associated with a mechanical LSD.

What is LSD?
LSD, Limited Slip Differential, is a mechanical device that allows an automobile to drive faster by limiting the difference which happens inside the wheel and outside wheel rate at different speeds. An automobile usually is equipped with a differential to absorb the difference between the outside wheel rotation and the inside wheel rotation on a corner. However, a normal stock differential has a disadvantage when you want to go faster. It slips and the automobile can become unstable. LSD limits the slip which makes a car unstable. ATS-LSD lock the slip close to 100% resulting in superb stability.

An automobile with ATS-LSD drives faster and has higher stability. Because of this high stability, the limit of the speed in corners is increased significantly. ATS-LSD works effectively not only in corners but also in straight courses such as in drag racing.

Even in a straight line, rapid acceleration makes one of the wheel slip.

Impact of the ATS-LSD on a FF Car
An FF Car always has an under steer problem when it is accelerated too hard during a turn. Therefore, it is critical to reach the clipping point with the angle at which the full power acceleration is available as soon as possible.

A car which is equipped with an ATS-LSD can approach the clipping point smoothly and then obtain dramatic acceleration from that point. (See the red car in the accompanying diagram).

Attention!
With ATS LSD oil, the mechanical and chattering noise of the ATS racing LSD is reduced to minimum level. We do not find the noise level annoying at all. However, each individual has his/her own tolerance level. We recommend using ATS LSD oil with your ATS LSD to minimize any such issues.

To avoid a surprise, we recommend you visit the shop and experience the noise level yourself. We also attend PDA (Performance Driving Association) events and EMRA time trials frequently. Visit us at one of these events and check out the LSD noise levels on our very own cars. We think you will agree the ATS LSD is a great addition to your racing car.
