What does replacing the motor mount do?
The stock motor mounts (p/n ATX – 4668182, MTX – 4668183) are fairly soft, in an effort to reduce noise and vibration. This allows a lot of engine movement, interfering with quick launches and fast shifting. It also leads to wheel hop, where the front tire(s) shake rapidly up and down during a racing launch. Extended wheel hop can damage engine and transmission mounting points, and other components. Replacing the front motor mount (FMM) in particular is an easy way to reduce this problem. Stiffer mounts are available via the aftermarket, as well as “Rexified” stock mounts, which have plastic inserts to firm up the OEM unit. It is even possible to use solid mounts. All of these will improve shifting and launch quality, reducing wheel hop. However, expect to feel increased vibration from the engine, particularly at idle.
