A limited slip differential is one of the most transformative mechanical upgrades available for a rear-wheel-drive Porsche 964 Carrera 2. Where a standard open differential allows power to escape through the wheel with the least resistance, exactly the wrong wheel at exactly the wrong moment, an LSD distributes torque to where traction exists, keeping the car planted, stable and controllable under power in every condition from damp roundabouts to fast track corners. The DRS Development OS Giken LSD for Porsche 964 C2 is the professional choice: a multi-plate Japanese differential with a proven motorsport pedigree, installed and set up by Porsche specialists to deliver the precise balance of street civility and track aggression that fast 964 owners demand.
Driving a Porsche 964 C2 on an open differential is a fundamentally different experience to driving the same car with a properly set-up LSD, and the difference is most pronounced in exactly the situations that matter most to an enthusiast driver. On corner exit, when you are accelerating hard from the apex, an open differential allows the inside rear wheel to spin while the outside wheel does the work of driving the car forward. The result is wheelspin, instability and wasted power. With the OS Giken LSD, torque is distributed across both rear wheels simultaneously, which means the car drives forward cleanly from the apex rather than crabbing sideways and waiting for the traction control to sort out the mess. In the wet, the improvement is even more dramatic, the additional traction available from two driven wheels rather than one makes the 964 significantly safer and more manageable in conditions where an open diff car requires constant caution. On track, the LSD allows you to apply full power earlier in the corner, which translates directly into faster exit speeds and lower lap times. The confidence this generates is not just psychological, it is measurable in the stopwatch. The OS Giken unit is chosen for this application specifically because its multi-plate design provides the progressive, controllable engagement that suits a driver-focused Porsche. It does not produce the sudden, jarring lockup of a basic clutch LSD or the unpredictable behaviour of a worn unit. It builds lockup progressively as power increases, which means the transition from open to locked is smooth and predictable, something that is essential for a car as sensitive to rear-end behaviour as the 964.
Ramp angle selection is one of the most important and least discussed aspects of LSD installation. The ramp angles on a multi-plate differential determine how quickly and how strongly the unit locks under acceleration and deceleration. A steep ramp angle produces aggressive, fast lockup, which maximises traction on corner exit but can produce oversteer behaviour under trail braking. A shallow ramp angle gives smoother, more progressive engagement, which is more predictable and comfortable but less aggressive under power. DRS Development selects and configures ramp angles during installation based on the car’s intended use and the driver’s feedback preferences, ensuring the LSD works in harmony with the driver rather than against them.
The OS Giken LSD is installed directly into the Porsche 964 C2 G50 gearbox and integrates with the factory differential carrier, crown wheel and gearbox casing without modification. DRS Development carries out the installation with full knowledge of the 964 G50 architecture, ensuring correct torque settings, correct lubricant specification and correct preload adjustment throughout the process. The finished installation is verified before the gearbox is refitted to the car.
If you want your Porsche 964 Carrera 2 to feel sharper, more planted and more rewarding to drive at the limit, the OS Giken LSD installed by DRS Development delivers one of the most significant performance transformations available for this platform. Contact DRS Development today to discuss your driving requirements and arrange installation.
The OS Giken LSD works best as part of a complete drivetrain and chassis upgrade. Explore more DRS Development performance components for your 964 C2:
