Audi B9 S4 Drivetrain Parts (2018-2023)

By stiffening up the drivetrain in your B9 Audi S4 you improve not only the handling of your car but its ability to get the horsepower right to the ground. Factory components are not always designed for performance and often times more towards the comfort of the driver. By swapping out the OEM drivetrain parts with upgrades such as solid transmission mounts or rear differential mounts you give your 2018-2023 Audi S4 a nice upgrade.
