034 Billet Aluminum Rear Subframe Mount Insert Kit For B9/B9.5 Audi Q5/SQ5

BACKORDERED: Orders placed today will hold your spot in line for the next available units, Early February 2026 ETA

The 034Motorsport Billet Aluminum Rear Subframe Mount Insert Kit for B9/9.5 Audi Q5/SQ5 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.

The B9/B9.5 Audi SUV chassis uses 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 on 034Motorsport's in-house B9 Audi SQ5 Development Vehicle before release. Installation is very simple and is completely reversible.
