034Motorsport is pleased to present Billet Aluminum Rear Differential Mount Inserts for the B9/B9.5 Audi A4/A5/S4/RS5 & Allroad!
The B9/B9.5 Audi A4/S4 & Allroad uses rubber rear differential mounts which deflect under load, causing the rear end to feel vague and loose, 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 B9 Audi A4 Development Vehicle before release. Installation is very simple and is completely reversible.
