The CTS Turbo rear subframe insert set is designed to eliminate unwanted movement, improve chassis stiffness and enhance driving characteristics in Audi S4, S5, Q5 and SQ5 vehicles on the B8 platform. The inserts reinforce the original rear subframe bushes, reduce their deformation and provide more efficient power transfer without a significant increase in noise, vibration and harshness (NVH).
Key features
- Reduce rear subframe movement for improved handling and stability.
- Made from high-strength aluminium machined from solid.
- Eliminate excessive play in the rear subframe and improve cornering response and road feel.
- Reduce drivetrain play, allowing more direct power transfer.
- Are not a permanent modification and work together with the original rear subframe bushes.
- NVH increase is minimal, so daily driving comfort is maintained.
Driving benefits
- More precise handling: less unwanted movement of the rear subframe for a more connected driving feel.
- Improved stability: better control of the rear of the vehicle during acceleration, braking and cornering.
- More efficient power transfer: less flex for improved throttle response and more efficient drivetrain operation.
The set is suitable for drivers who want to improve driving dynamics without sacrificing comfort during everyday use.
