034 Motorsport - Billet Aluminium Rear Subframe Insert Kit, BMW F20/F30 Chassis - 034-601-0052.

The 034Motorsport Billet Aluminium Rear Subframe Insert Kit for the BMW F20/F30 chassis is designed to limit movement in the factory rear subframe mounts to maintain proper suspension geometry when cornering, and improve the responsiveness of the rear suspension and differential.

By filling small voids in the four factory mounts as well as limiting vertical movement, this insert set eliminates the associated slop to ensure that you experience a more refined, connected driving experience, especially when driving at the limit. These billet aluminium parts will not pack and wear over time and offer a lasting performance improvement.

The BMW F20/F30 chassis use rubber rear subframe mounts that deflect under load, causing the rear end to feel vague and loose, as well as leading to less-than-optimal suspension geometry and increased understeer. These precision-machined billet aluminium inserts are designed to fill voids in the factory rear subframe mounts, and limit subframe movement without sacrificing ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin. The result is a more refined, connected driving experience, as well as improved effectiveness of aftermarket rear sway bar upgrades and suspension components.

Designed to work in conjunction with the factory rubber mounts, this insert package was engineered using CAD software and thoroughly tested and refined to provide a significant improvement in handling performance and feel.

These inserts were tested extensively by 034Motorsport and independent BMW enthusiasts before release on multiple F2x/F3x vehicles. Installation is very simple, can be performed in under an hour, and is completely reversible.
