LS.D. refers to Limited-Slip Differential Gear, used in the center and final-drive, differential-gear section of m automobiles. While standard "open-differential" is commonly used on mundane production vehicles to allo rotational difference of outside and inside wheels, in motorsports application requires that the driving wheel power to the road surface regardless of condition, surfaces, driving style, and automobile design weaknesses

The purpose of LSD is to limit the free-wheeling' of any wheels that are slipping, or airborne, and otherwise p power from transferring to the ground. LSD system does this by providing a certain controlled amount of lo each of the driving wheels, so that the power is transmitted to all driving wheels affected.

Common and generic discussions about LSD systems, floating around the modern Internet, stress that the LSI simply increase traction. Or, simply claim to provide grip for "better performance." However, we at Cusco bel design our products based around principles that are much deeper than these simple generalizations. Our rac background and deep R&D experience goes back nearly half century, and as a company founded in 1977, our have always stayed true to advanced motorsport benefits and on-going development.

We believe that the LS.D systems should work to provide drivers with least amount of compromises, and fine-aspects to cater a precise character that a driver might need for a very wide variety of motorsport stages. It sh simply lock the differential, but be available to lock when needed, and not lock when it isn't optimal to do so. provides many elements that can be tuned and tailored, and have multiple system configuration to match the how it locks, when it locks, and releases, and adjustability of strength of the lock, and responsiveness of each of factors.

Cusco also understands that the Limited Slip Differential systems can affect the overall handling of the car, there the chassis and suspension requirements and optimization will also change accordingly. It is the cumulative ov of every component of the car, which will determine the settings and needs of each of these items. This is why a full-line of chassis bracing, suspension systems, and dynamic alignment correction components to setup a car potential, counting on each element to achieve the best balance, and closer to the goal of the driver and teams competitions, or provide more tactile road cars for the discerning owners.

At Cusco, we call this adherence to constantly strive for total balance, and relentless tuning to be ever closer to p with a single Japanese word, "TAKUMI."
