MMR rear cradle inserts for BMW F2x & F3x

Description

Our MMR Performance rear subframe bushing kit for BMW F-Series (F2x and F3x) is designed to limit movement of the original rear subframe mounts, thus maintaining optimal suspension geometry when cornering. Installation is very simple, takes less than an hour, and is fully reversible.

By filling the small gaps in the four original mounts and limiting vertical movement, our inserts eliminate play and provide a more precise and responsive driving experience, especially during sporty driving. Made from machined aluminum, these parts are virtually indestructible and guarantee a lasting performance improvement.

The chassis of the BMW F2x and F3x use rubber rear subframe mounts that deform under load, resulting in imprecise and unstable rear suspension, suboptimal geometry, and increased understeer. These precision-machined aluminum inserts are designed to fill the gaps in the original rear subframe mounts and limit subframe movement without compromising ride comfort or generating additional noise, vibration, or harshness in the cabin. The result is a more precise and responsive driving experience, as well as increased effectiveness of the rear anti-roll bars and adaptive suspension components.

CNC machined part made of 6061-T6 aluminum.

Fills the void left by the rubber bushings of the original cradle.

No additional transmission of NVH (noise, vibration and harshness) inside the vehicle.

Easy installation without dismantling the cradle.

Reduces rear cradle movement during starts and accelerations.

Contributes to maintaining optimal suspension geometry under dynamic conditions.

Concerned about noise? NVH measures the amount of noise, vibration, and harshness transmitted into the passenger compartment. Based on user feedback, MMR inserts transmit virtually no NVH into the passenger compartment. Since NVH is subjective, some users may perceive it differently than our assessment. If you experience higher NVH than indicated with this product, please check the installation to ensure the components are properly fitted.

These inserts have been extensively tested by our in-house teams and independent BMW enthusiasts on numerous F2x and F3x vehicles prior to their release. Our differential inserts are compatible with diesel, petrol, manual, and automatic versions.
