If you need the absolute best in traction for your Miata, a Cusco LSD (Limited Slip Differential) is what you seek. Cusco LSDs allow you to chose 2 of 3 settings with each unit just with a simple overhaul.

In the Type RS, it's springs absorb the initial torque. Compared to the Type MZ, the Type RS' initial torque comes on more gently. The response of the RS has lower friction and in turn, is better.

The Low Initial Torque means Less Power Loss. This equates to lower lap times, even for a mildly tuned vehicle. The low pressure on the clutch plates improves durability and lowers chatter. To top it off, the reduced pressure allows the driver to change the LSD oil less frequently.

Steady coil movement is assured by special precision springs set in the pressure plate. These springs are made to be resilient and allow for stable operation. Because these plates do not utilize a cone clutch, they do not stick and allow for increased longevity.

The Type RS transfers extreme power without slipping and responds quickly with pedal inputs. This differential is perfect, whether you're drag racing or going for huge drifts.

Three Ways To Set Up Your LSD

• A 1 Way LSD is specially suited for front wheel drive cars and the front axle of AWD cars. It activates only under acceleration, allowing the better handling when you lift off the throttle. This is a great way to improve lap times.
• A 1.5-way LSD activates fully under acceleration, but does not activate fully under deceleration. This decreases understeer compared to a 2-way LSD. This is recommended for drivers having difficulty with 2-way LSD understeer, or the braking on a one-way LSD.
• A 2-way LSD is recommended on rear wheel drive cars and AWD rear axle cars.. Because it activates on both acceleration and deceleration, it is recommended for those who prefer hot driving action and big angle drift.
