Overview of Differential Types
Fully Locking Differentials
- Welded Differentials
Welded differentials are commonly used in budget drift modifications. They permanently lock the two rear wheels together, ensuring both wheels receive equal power, which is crucial for maintaining drifts. However, the downside is increased tire wear and a less comfortable ride during daily driving.
- Electric and Air Lockers
Limited-Slip Differentials (LSD)
Torsen (Torque Sensing) limited-slip differentials use a gear system to distribute torque between the wheels. Without relying on clutch plates, they are more durable and provide smoother operation. Torsen LSDs automatically adjust the locking degree based on road conditions, making them ideal for drift activities requiring high stability and consistent performance.
- Viscous LSD (vLSD)
- Torque Vectoring Differentials (TVD)
Why Open Differentials Are Not Suitable for Drifting
Open differentials are common in most commuter cars, allowing each wheel to rotate independently. While beneficial for smooth turning and everyday driving, they pose a significant drawback for drifting. In drifting, the wheel with less traction receives more power, causing a loss of acceleration when needed. This makes initiating and maintaining a drift extremely difficult.
