There has been a lot written and a lot talked about the LSD and its function. KAAZ-SPORTS has been developing Limited Slip Differentials for many many years and over this time they have learned all of the best practices in LSD design and performance. Below explains how LSD works and the benefits using a KAAZ LSD. Much of this has been translated from the Japanese catalogues and also form time that members of Limited-Slip.com have spent with KAAZ Engineers both in the UK and in Japan.

A standard differential in your car is known as a "free" diff. This means that each wheel is free to rotate on its own. Should one wheel spin or go onto a muddy surface all the power is transferred to the wheel in the mud because as it is the easiest route for the transfer of power. The down side of this is that you lose traction and forward momentum. This is not an ideal situation in a competition event as you are looking for forward traction at much as possible.

Inside a KAAZ limited slip differential or LSD are a combination of special flexible plates and a pin in-between them. Then as the car accelerates the pin is pushed between the plates moving them out and in turn "locking the diff" With a diff locked if a wheel go onto a muddy surface then the plates work to put the power to the wheel that is not slipping.
Also when you decelerate the pin moves to a new position and again presses the plates to give you good control under braking.
