M Performance LSD (F2X M140i/M240i, F3X 340i/440i Auto)
£2,000.00
BMW M Performance Limited Slip Differential for the F2X M140i/M240i and F3X 340i/440i. Automatic transmissions only.
The biggest drawback of the M140i is its lack of limited slip differential, meaning that getting power to the ground effectively is hugely frustrating. However this can be fixed, with a BMW Performance Limited-Slip Differential.
Genuine BMW part. 2.81 final drive.
