Rear Subframe Insert Set B8 Audi A4/A5/Allroad

HW-558

The CTS Turbo Rear Subframe Insert Set is designed to reduce subframe movement, enhance chassis rigidity, and improve overall handling in your Audi B8 A4, A5, and Allroad. These inserts reinforce the factory subframe bushings, reducing deflection and improving power transfer without introducing significant NVH.

Key Features:

  • Improves chassis stability and reduces subframe movement.
  • Made from durable billet aluminum for maximum strength and longevity.
  • Enhances handling precision and road feedback.
  • Reduces drivetrain slop, resulting in better throttle response and power delivery.
  • Simple, non-permanent installation—works with factory subframe bushings.
  • Minimal NVH increase for a balance of comfort and performance.

Performance Benefits:

  • Tighter handling: Eliminates unwanted movement in the rear subframe, making the car feel more connected to the road.
  • More predictable cornering: Improves rear-end stability, especially during hard acceleration, braking, and cornering.
  • Enhanced drivetrain efficiency: Reduces deflection for more efficient power transfer to the wheels.

Ideal for daily drivers and performance enthusiasts looking to improve their Audi’s driving dynamics without compromising ride comfort.

Fitment:

  • 2009-2016 Audi A4 (B8/B8.5)
  • 2008-2017 Audi A5 (B8/B8.5)
  • 2013-2016 Audi Allroad (B8/B8.5)
NB: Before ordering, check the rear subframe mounts. If the metal cover is oriented front-to-back (towards the front/rear) then the inserts are compatible. If the metal cover is oriented left-to-right (towards the wheels)
then the inserts will not fit, use CTS-HW-559 instead.

Always replace the subframe bolts with genuine Audi parts, and torque to spec: 115Nm + 90deg.
Each vehicle requires 4x WHT004756A.

Please make sure this part matches your vehicle before ordering. We run a compatibility check prior to dispatch using your registration number (UK) or the last 7 digits of your VIN.
