I figured out that we need a differential thread in this forum.
Please share your opinion.
What differential you have?
Do you like it?
Will you buy it again in future? (if not, what would you get?)
Here are some of aftermarket LSD available for our cars.
Quaife Automatic Torque Biasing (ATB) differential
Quote:
BENEFITS- Maximizes traction and minimizes wheelspin
- Proven in drag and circuit racing, rallying and road use
- Eliminates torque steer and snatching in fwd cars compared to conventional LSD
- Maintenance free design and retains standard axle lubrication
- Produced from CORUS steel billets throughout
- CAD designed and CNC machined then inspected to ISO 9001 standards
- Used by Ford, GM and Daimler-Chrysler as original equipment
- Massive range available, from Alfa Romeo to Volvo
- Beware of cheap imitations!
Reliability is total; the ATB Helical LSD units are designed using the latest CAD techniques and are CNC machined to ultra-tight tolerances from the very best CORUS steel billets. The completed units are then subject to rigorous in-house inspection on a tri-coordinate measuring machine before being dispatched to the customer.
Such quality means that unlike a conventional plate-style LSD the QUAIFE ATB Helical LSD unit requires no special maintenance or rebuilds, long lasting and it retains the standard method of lubrication, making for an easy, pain-free upgrade.
Proven in rallying, racing and on the road, the ATB Helical LSD differential offers safe, reliable, winning performance – everything you’d expect from a QUAIFE product.

Nismo GT Pro Clutch Type Limited Slip Differential

The GT L.S.D. Pro is the ideal solution for drivers who are spending too much time working on their LSD. Otherwise identical to the standard GT L.S.D., the GT L.S.D. Pro adds one unique feature: you will be able to re-set your initial torque with just a turn of your socket wrench and without disassembling your LSD. With a low, middle and high setting (6.5 - 8.5 - 14.0kgf·m), easy adjustments can be made for changing driving styles, tires, suspension, tuning or track conditions. As initial torque decreases with aging parts, changing the initial torque setting -LOW two times, MIDDLE once- will save you money on overhaul costs.

Carbonetic Carbon LSD
Quote:
The CARBONETIC LSD (Limited Slip Differential) responds to the demands of the novice or the professional driver seeking the most dependable control when competing in road racing, time attack, drifting competition or a rally event.
A vehicle’s kinetic performance is largely determined by the potential of the selected LSD. CARBONETIC release the Carbon LSD and the Metal LSD. Those LSD have different character. You can choose the best one for your vehicle.
Benefits
• More than twice the differential lock strength of metal LSDs
o High carbon friction material increases the coefficient of friction
Friction coefficient of metal plate in oil: 0.05 ~ 0.15
Friction coefficient of carbon plate in oil: 0.25 ~ 0.35
• Low initial drag resistance with reliable performance - surpasses more than 5 times that of metal LSDs
• Acceleration control range in excess of 10 times that of metal LSDs
o Vehicle will remain on track in and out of turns for exacting driving control
• More than 30 times the thermal decomposition resistance of metal LSDs
o Promotes increased driving skill - repeated time attacks or under loads of performance cars
• More than 70 times the service life of metal LSDs
• Virtually noiseless performance
• Compatible with automatic transmission vehicles

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.

Cusco LSD Type RS
Quote:

The Cusco Type-RS differential is made for both the manual and automatic transmissions. Available in 1, 1.5, and 2 way variants, this diff is customizable enough to suit any of your needs. The Type-RS features a spring setup that is designed for low initial torque to be transferred to the wheels. Allowing the torque to be transferred more gradually keeps the plates from being damaged through shock and makes the differential more sensitive to user input. This results is a longer lasting, more durable differential. Ideal for mildly tuned vehicles being used for drifting and circuit racing.

Cusco LSD Type MZ
Quote:
Then there's the Type-MZ differential available for those of you with automatic transmissions. The Type-MZ uses cone plates and increases the number of clutch plates over the RS (from 8 on each side to 10) to increase initial torque. Due to the solid engagement characteristics of the Type-MZ, it is more suited for drifting and drag racing.
Features of the Type-MZ:- Better transfer of power from the engine to the drivetrain with minimal loss of power
- Cone plates for high initial torque
- Increased number of clutch plates = increased response and torque transfer
- Forged internals for high durability

FAQ:
What's the difference between 1 way, 1.5 way and 2 way LSD’s?
1 way lsd: An LSD is activated only when the throttle is on and when the internal cam rings has an angle on only one side.1.5 way lsd: The angle of the cam rings for the off-side is very close to 5-20 degrees which will make the LSD ineffective when the throttle is off (during deceleration).The Across 1.5-Way LSD will work similar to 1-Way LSD during deceleration.
2 way LSD: The 2-Way cam rings angle are cut in the same degree on both sides (throttle on and throttle off sides). A 2-Way LSD will activate during both acceleration and deceleration. 2 way is a popular choice for drifting.
