The CTS Turbo Rear Subframe Insert Set is engineered to reinforce the rear subframe bushings, reduce movement, and improve handling precision in your Audi B9 A4, A5, S4, S5, and RS5. By filling the voids in the factory bushings, these inserts minimize subframe deflection, ensuring better power transfer and chassis stability without significant NVH increase.

Key Features:

  • Reduces subframe movement for improved handling and stability.
  • Made from high-strength billet aluminum for durability and long-lasting performance.
  • Enhances steering response and road feel by eliminating excessive play in the rear subframe.
  • Reduces drivetrain slop, leading to more direct power delivery.
  • Simple installation—works with factory subframe bushings, no permanent modifications required.
  • Minimal NVH increase, maintaining daily driving comfort.

Performance Benefits:

  • Sharper handling: Eliminates unwanted movement in the rear subframe for a more precise and controlled driving experience.
  • Enhanced stability: Improves rear-end control during acceleration, braking, and cornering.
  • More efficient power transfer: Reduces flex for better throttle response and drivetrain performance.
Perfect for enthusiasts and spirited drivers looking to improve the driving dynamics of their Audi B9 without compromising ride comfort.
