034Motorsport Audi Rear Subframe Mount Insert Kit B8/B8.5 (S4, RS4, S5, RS5, Q5 & SQ5)
The 034Motorsport Billet Aluminum Rear Subframe Mount Insert Kit for B8/B8.5 Audi S4/RS4, S5/RS5, 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.
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 aluminum parts will not pack and wear over time, and offer a lasting performance improvement.
Please Note: The four factory rear subframe bolts can be reused at the torque specified in our Installation Guide. If you wish to purchase new stretch factory hardware, the part number for these bolts is WHT004756A.
The B8/B8.5 Audi S4/RS4, S5/RS5, and Q5/SQ5 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.
