Description
MMX BMW F2x/F3x Billet Rear Subframe Insert Kit limits movement in the factory rear-subframe mounts, helping the suspension maintain more consistent geometry when the car is cornering or accelerating.
The application-specific billet inserts work with the original mounts and can be removed to return the vehicle to standard. MMX describes installation as straightforward and achievable in under an hour by a suitably equipped installer.
