OS Giken Tuning Service

OS Giken LSD Custom Tuning Service - SLG Spec
 
If you’re installing an OS Giken LSD—or already have one in your car—we highly recommend a custom tune to get it completely dialed in for your setup. We gather detailed information about your vehicle’s weight, power, tire choice, suspension, and driving style to build a tailored spec together with OSGUSA that maximizes performance and drivability.
 
Add this service when ordering a new differential so it arrives pre-tuned, or ship your existing OS Giken unit in for recalibration.
 
Why Tune Your OS Giken LSD?
Most LSDs come with aggressive factory settings designed for extreme grip scenarios like soft slicks or drift applications. On 200TW tires commonly used in time attack and wheel-to-wheel racing in the USA, these aggressive settings often lead to unwanted understeer and reduced corner-exit performance.
 
A proper custom tune transforms the differential’s behavior:
Improves corner entry stability
Reduces push on throttle
Maximizes available grip
Delivers stronger forward drive off apex
Makes better use of your engine’s torque and your tires’ traction window
 
This is one of the highest-value handling upgrades you can do—especially for cars upgrading from a stock diff.
 
What’s Included
Personal phone consultation to spec the tune
Custom internal setup tailored to your car and driving style
All internal parts required for the adjustment
Return shipping within the USA
