CTS Turbo rear subframe inserts for Audi A4/A5/Allroad B8

The CTS Turbo rear subframe insert kit is designed to reduce subframe movement, increase chassis stiffness and improve handling on Audi A4, A5 and Allroad B8 vehicles. The inserts reinforce the factory subframe bushes, reduce their deformation and improve power transfer without significantly increasing noise, vibration and harshness (NVH).

Key features

• Improves chassis stability and reduces rear subframe movement.
• Made from durable machined aluminium for high strength and a long service life.
• Improves handling precision and feedback from the road.
• Reduces unwanted drivetrain play, improving throttle response and power transfer.
• Simple, reversible installation – used together with the factory subframe bushes.
• Minimal increase in NVH provides a good balance between comfort and performance.

Driving benefits

• More precise handling: reduces unwanted rear subframe movement, making the vehicle feel more connected to the road.
• More predictable cornering behaviour: improves rear-end stability during hard acceleration, braking and cornering.
• More efficient power transfer: less deformation means more efficient power transfer to the wheels.

Suitable for everyday use and drivers who want to improve their Audi’s driving dynamics without significantly affecting ride comfort.

Important before installation

Check the rear subframe mounts before ordering. If the metal cover is oriented longitudinally, from the front towards the rear of the vehicle, these inserts are compatible. If the metal cover is oriented transversely, towards the left and right wheels, the inserts are not compatible; in this case, use CTS-HW-559.

Always replace the subframe bolts with genuine Audi parts. The tightening torque is 115 Nm + 90°. Each vehicle requires 4x WHT004756A.

Weight: 0.91 kg

Suitable for: Audi A4 III (B8), Audi A5 I (B8).

Approval

This part has no TÜV certification (ABE, TTG or Teilegutachten).
