Rear Subframe Insert Set

The CTS Turbo Rear Subframe Insert Set is meticulously engineered to reinforce the rear subframe bushings and significantly reduce unwanted movement in your Audi B9 A4, A5, S4, S5, and RS5. These inserts work by filling the voids present in the factory bushings, which effectively minimizes subframe deflection. This process leads to improved power transfer and enhanced chassis stability without introducing a substantial increase in Noise, Vibration, and Harshness (NVH). Key features of this insert set include the reduction of subframe movement for improved handling and stability, and they are constructed from high-strength billet aluminum for exceptional durability and long-lasting performance. The design also enhances steering response and road feel by eliminating excessive play in the rear subframe, and it reduces drivetrain slop for more direct power delivery. Performance benefits are notable, offering sharper handling through the elimination of unwanted rear subframe movement for a more precise driving experience, and enhanced stability by improving rear-end control during acceleration, braking, and cornering. The more efficient power transfer is achieved by reducing flex, leading to better throttle response and overall drivetrain performance. This makes the insert set ideal for enthusiasts and spirited drivers seeking to elevate their Audi B9's driving dynamics without significant compromises to ride comfort. This product is designed to fit the 2017-2024 Audi A4 (B9/B9.5), 2017-2024 Audi A5 (B9/B9.5), 2017-2024 Audi S4 (B9/B9.5), 2017-2024 Audi S5 (B9/B9.5), and 2018-2024 Audi RS5 (B9/B9.5).
