M Factory Final Drive Gear | BMW E30 325
While engine performance upgrades can net you considerable horsepower and torque, for the E30 325, significant gains are difficult to come by.
Instead of increasing engine power output, change the way it's converted to wheel speed by changing your final drive ratio.
The MFactory 5.43 Final Drive Gears offer a dramatic increase in acceleration, giving you an average gain of 10-15% in torque throughout the entire rev-range.
