The CTS Turbo rear subframe insert set is designed to reinforce the rear subframe bushes and reduce its movement on Audi A4, A5, S4, S5 and RS5 B9/B9.5 models. The inserts fill the voids in the factory bushes, reducing subframe deflection and helping to improve power transfer and chassis stability without a significant increase in NVH – noise, vibration and harshness.
Key features:
- Reduce rear subframe movement for improved handling and stability.
- Made from high-strength solid aluminium for durability and long-term use.
- Improve steering response and road feel by eliminating excessive play in the rear subframe.
- Reduce unwanted movement in the drivetrain, enabling more direct power transfer.
- Easy to install in combination with the factory bushes, without permanent modifications.
- Minimal increase in NVH, so everyday driving comfort is largely retained.
Driving benefits:
- More precise handling: eliminating unwanted rear subframe movement provides a more precise and controlled driving feel.
- Improved stability: better control of the rear of the vehicle during acceleration, braking and cornering.
- More efficient power transfer: less flex means better throttle response and more efficient drivetrain operation.
The set is suitable for drivers who want to improve the driving characteristics of their Audi B9 without significantly reducing driving comfort.
