Racingline MQB/RS Subframe Collars

RacingLine Performance Rear Subframe Insert Kit for MQB and MQB 'Evo' fills the voids in the factory rear subframe bushes to limit subframe and differential movement under load and maintain correct rear suspension geometry during dynamic driving.

❌ The OEM problem

MQB/MQBE vehicles use soft rubber bushes in the rear subframe, which:

• 🔄 deform noticeably under load

• 😕 create a "floating" and vague feel from the rear

• 📐 lead to suboptimal geometry during hard cornering

🎯 RacingLine's solution

By filling the voids in the factory bushes, the Insert Kit:

• ❌ eliminates the inevitable "squidge"

• ⚖️ stabilises the subframe and differential

• 🎯 provides a more precise and connected feel behind the wheel, especially in corners

⚙️ Construction and comfort

• 🧱 Precision CNC-machined billet aluminium inserts

• 🔧 Slip-fit into the bores – bolt-on OEM+

• 🔇 No noticeable increase in NVH (noise, vibration, harshness)

• 🛞 Maintained ride quality

The result is that feeling every enthusiast seeks – a tighter connection between car and driver 💪

🕒 Even greater effect on older cars

The benefits are even more pronounced in older cars, where the factory rubber in the bushes is "tired" and allows for greater deformation.
