Product Details

034Motorsport is pleased to present Billet Aluminum Rear Subframe Mount Inserts for the B8/B8.5 Audi A4/A5/Allroad!

The B8/B8.5 Audi A4/A5/Allroad use rubber rear subframe mounts which 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 aluminum 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 Audi enthusiasts before release on multiple B8/B8.5 vehicles. Installation is very simple, can be performed in under an hour, and is completely reversible.
