The helical gearing manages friction distribution within the differential. When torque is applied to the helical gear system, a force is created that pushes the gear against the differential housing, generating friction. The higher the torque, the greater the thrust force, directly proportional to the amount of torque. This allows the Bratex differential to handle a considerable traction imbalance, even under high-power conditions, such as accelerating out of a high-speed corner. However, in low-torque conditions, the differential can differentiate quietly and smoothly, making it ideal for normal road driving. The Bratex differential uses the popular parallel-axis helical gear configuration, optimized for uniform load distribution. It is designed with a 5:1 torque ratio, which means that if one wheel loses traction, the wheel with more grip can receive five times more torque than the slipping wheel. However, five times zero is still zero, so all these helical limited-slip differentials work best when both wheels are on the ground and the slipping wheel still retains some traction. In practice, this is rarely a problem, as there is always some resistance on the slipping wheel; nevertheless, some drivers skillfully use left-foot braking to partially lock the spinning wheel.
