The BMW F2X/F3X Chassis uses rubber differential mounts that deflect under load, causing the delay of power transfer to the rear tires, as well as leading to less-than-optimal handling characteristics during on-throttle and off-throttle transitions. These precision-machined billet aluminum inserts are designed to fill voids in the factory rear differential mounts, and limit differential movement under load 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.

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 on 034Motorsport’s in-house F30 BMW 340i Development Vehicle before release. Installation is very simple and is completely reversible.
