Cusco Type MZ 1 1/2 Way LSD Mazda Miata NA / NB

Description
Type MZ LSD; 1.5Way
The Type MZ LSD had been greatly improved using most parts that comprise the Type RS. Its has evolved as well through countless R+D tires, tests and races to create the most balanced LSD for your specific use. The Oil Through System uses the same forged parts used in the Type RS. The Type MZ differs in the way the initial torque is developed. The clutch plates have been increased from eight to ten plates one each side increasing the LSD performance. It responds more to the high power with higher durability. There are three ways to set your Cusco Limited Slip Differentials: 1 way, 1.5 way and 2 way. * 1 way LSD: Specially suited for front wheel drive cars and AWD front axle cars. Activates under acceleration, and acts as a true LSD when the throttle is off. This CUSCO 1 way LSD will improve lap times without a doubt. * 1.5 way LSD: Activates under acceleration while the under-steer under deceleration is less than on a 2 way LSD. Recommended for those who have a hard time with under-steer. * Two way LSD: Recommended on rear wheel drive cars and AWD rear axle cars. Activates on both acceleration and deceleration. Recommended for those who prefer aggressive driving and big angle drifting.

Type RS LSD; 1.5Way

The Cusco Type RS LSD had proved to be capable of competition use in the All Japan Gymkhana Championship without overhauling a single time during the season. With all drivers and teams finishing with good or championship results at the end of the season. According to Cusco's in house research, initial torque is 50 to 70% lower compared to the conventional cone plate type LSD enabling lower drive friction and better response. * Low power loss means better lap times for even the mild tuned of cars * Chattering is kept low * Improved durability as clutch plates are low pressured * The LSD efficiency is higher with smoother oil flow between plates. * Special precision springs, set in the pressure plate, assure steady coil movement * Clutch plates do not stick together like conventional cone plate type LSDs. Therefore less clutch plate wear or deterioration occurs. There are three ways to set your Cusco Limited Slip Differentials: 1 way, 1.5 way and 2 way. * 1 way LSD: Specially suited for front wheel drive cars and AWD front axle cars.

Performance driving and high output engines puts strain on the drivetrain and can sometimes lead to failing components, such as broken gears or input shafts. The goal of the OS Giken Close Ratio Gear Kit is to reinforce the transmission internal components while maximizing an engine’s potential by providing custom gear ratios for performance driving. Each OS Giken gear component is designed and created from high-quality forged materials, and then undergoes hard shot peening, resulting in increased strength and durability. Furthermore, the gears are helical-cut, rather than straight-cut, to maintain a quiet and smooth operation, accomplishing full comfort for street driving as well as reliability for racing.

Description
Super Lock LSD; Spec-S

The OS Super Lock LSD is the culmination of over four years of extensive research and development that led to a revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total). Combined with our patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it suitable for both street and racing performance. *Superior Design* * Miniaturized pressure ring and a superior spline-through-side-gear design allows for fitment of more friction plates (up to 2x as many as competitors versions), offering true 100% lock capability. * Patented pressure ring design allows for smooth, progressive locking * LSD case has a relief cut-out for the cone spring, resulting in minimal cone spring degradation and enhanced durability. *Superior Construction* * All components are chemically heat treated for maximum durability * All components are constructed from a high-grade steel alloy Gears are raw-forged for maximum strength * Clutch disks are precision-machined simultaneously on both sides to extremely tight tolerances resulting in minimal warpage. * LSD case is machined from a single billet piece to ensure uniformity. *Superior Overall Performance* * The OS LSD standard spec allows for low preload while still retaining a fully progressive 100% lock capability; basically, the vehicle will feel like driving on an open diff in slow turns / street driving, but can still transmit maximum power to the drive wheels under load. * Operation is ultra quiet, and the progressive locking allows for smooth, predictable locking. Especially when replacing an open diff, equipping OS LSD will completely improve the driving experience while maintaining everyday drivability. * Due to the precision manufacturing, high-grade materials, and unique design, a break-in period nor rebuild is required for OS Giken LSD’s. OS LSD is purposefully over-engineered to offer the best performing, most durable clutch-type LSD available. * Aside from the performance advantage and stock-like feel at slow speeds, vehicles equipped with OS LSD are more stable in all road/weather conditions, allowing for a safer driving experience. *Tunability* * Initial torque can be adjusted by using thicker / thinner cone springs * Lock progression timing can be adjusted by using stiffer / weaker pressure ring springs, allowing the progression of full lock to be fine-tuned to the vehicle/driver. * Ramp angles can be customized by swapping the pressure ring and iron cross for even more tuning possibilities. * TCD spec disks can be installed for increased oil cooling and even smoother operation. *Super Lock LSD – Spec X* For vehicles that are heavily modified or are particpating in specific forms of motorsports, we offer the Spec-X LSD. The custom order Spec-X is available in 1-way, 1.5-way, and 2-way configurations and can be made with custom cam angles, lock timing, and initial torque settings. *Traction Control Differential (TCD)* The innovative TCD system uses specialized oil channels and pathways to provide maximum oil flow and minimal noise, resulting in exceptionally smooth locking.

Combined with our patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it suitable for both street and racing performance. *Superior Design* * Miniaturized pressure ring and a superior spline-through-side-gear design allows for fitment of more friction plates (up to 2x as many as competitors versions), offering true 100% lock capability. * Patented pressure ring design allows for smooth, progressive locking * LSD case has a relief cut-out for the cone spring, resulting in minimal cone spring degradation and enhanced durability. *Superior Construction* * All components are chemically heat treated for maximum durability * All components are constructed from a high-grade steel alloy Gears are raw-forged for maximum strength * Clutch disks are precision-machined simultaneously on both sides to extremely tight tolerances resulting in minimal warpage. * LSD case is machined from a single billet piece to ensure uniformity. *Superior Overall Performance* * The OS LSD standard spec allows for low preload while still retaining a fully progressive 100% lock capability; basically, the vehicle will feel like driving on an open diff in slow turns / street driving, but can still transmit maximum power to the drive wheels under load. * Operation is ultra quiet, and the progressive locking allows for smooth, predictable locking. Especially when replacing an open diff, equipping OS LSD will completely improve the driving experience while maintaining everyday drivability. * Due to the precision manufacturing, high-grade materials, and unique design, a break-in period nor rebuild is required for OS Giken LSD’s. OS LSD is purposefully over-engineered to offer the best performing, most durable clutch-type LSD available. * Aside from the performance advantage and stock-like feel at slow speeds, vehicles equipped with OS LSD are more stable in all road/weather conditions, allowing for a safer driving experience. *Tunability* * Initial torque can be adjusted by using thicker / thinner cone springs * Lock progression timing can be adjusted by using stiffer / weaker pressure ring springs, allowing the progression of full lock to be fine-tuned to the vehicle/driver. * Ramp angles can be customized by swapping the pressure ring and iron cross for even more tuning possibilities. * TCD spec disks can be installed for increased oil cooling and even smoother operation. *Super Lock LSD – Spec X* For vehicles that are heavily modified or are particpating in specific forms of motorsports, we offer the Spec-X LSD. The custom order Spec-X is available in 1-way, 1.5-way, and 2-way configurations and can be made with custom cam angles, lock timing, and initial torque settings. *Traction Control Differential (TCD)* The innovative TCD system uses specialized oil channels and pathways to provide maximum oil flow and minimal noise, resulting in exceptionally smooth locking.
