034Motorsport B9 Rear Subframe Bush Inset Kit
034Motorsport offers a precision-engineered rear subframe insert kit for the B9 Audi A4, crafted from T6-6061 billet aluminum and finished with clear anodizing for durability. These inserts fill the voids in the factory rear subframe mounts, significantly reducing deflection under load and delivering crisper, more precise rear-end handling without introducing noticeable NVH into the cabin.
Designed to work alongside the factory rubber mounts, the inserts were developed using CAD software and thoroughly tested to improve overall vehicle feel and performance. Installation is straightforward and fully reversible, allowing you to upgrade your handling without permanent modification.
