034 Motorsport - Billet Aluminium Rear Subframe Insert Kit - Audi B9 A4/A5/S4/S5/RS5 - 034-601-0046
Improve rear-end stability, precision, and chassis feel with the 034Motorsport Billet Aluminium Rear Subframe Insert Kit for the Audi B9 platform. The factory rubber subframe mounts allow excessive movement under load, which can create a vague rear-end feel, reduce suspension efficiency, and contribute to understeer.
This kit fills the voids in the OEM mounts with CNC-machined billet aluminium inserts, dramatically reducing subframe deflection without increasing cabin noise or harshness. The result is a sharper, more connected driving experience—especially beneficial when paired with an upgraded rear sway bar or performance suspension components.
