MFactory Final Drive Gears for BMW E82 E90 E92 E88 F20 F21 F22 F23 F30 F31 - M135i, M235i, 135i, 335i, 435i
Transform the way your BMW accelerates with the MFactory Final Drive Gears. This premium ring and pinion gear set is the proven upgrade for quicker acceleration, sharper response and stronger performance on road and track. By changing the final drive ratio you can experience a dramatic improvement in acceleration, with an average 10 to 15 percent increase in torque felt through the entire rev range compared to the OEM final drive. Ideal for spirited road driving, track days, drag racing and fast road builds on BMW 135i, 335i, 435i, M135i and M235i platforms.
At Nforcd we run MFactory gears on our own builds and customer cars. Feedback has been excellent for drivability, durability and the way they wake the car up. If you want faster in-gear pull, stronger exits and a BMW that feels alive, this final drive upgrade delivers.
