What is the best type of rear end, differential, for car racing?
Racing cars require a special type of differential for the rear end in order to provide the best performance. The best type of differential for car racing is the limited-slip differential (LSD), which is designed to reduce wheel spin and improve traction. The LSD is usually made up of clutch plates and a special gear oil, and is also known as a torque-sensing differential. It is able to sense the difference in speed between the two driving wheels, and can adjust the power delivery accordingly. The helical LSD is another popular option, as it is much quieter and more efficient than the clutch-based type. Both types are more expensive than the open differential, but offer improved performance and handling.
