Compared to the standard 3.5 front differential, the 3.9 differential provides improved power transfer to the front wheels, resulting in faster acceleration, better traction, and more responsive handling, especially during cornering and high-speed driving.
The manual transmission option for the Subaru Impreza WRX is a close-ratio, five-speed unit that was designed to provide quick and precise gear changes.

This engine is mated to the close-ratio manual transmission and sends power through the upgraded 3.9 front differential to all four wheels of the vehicle.
