Racingline Rear Subframe Bush Inserts – Skoda Octavia VRS

The RacingLine Rear Subframe Insert Kit for the MQB & MQB ‘Evo’ chassis fills the voids in the factory rear subframe mounts to limit subframe and differential movement under load to maintain proper rear suspension geometry during hard cornering.

By filling the voids in the factory mounts, the Rear Subframe Insert Kit eliminates the inevitable ‘squidge’ to ensure that you experience a more precise, connected driving experience, especially during hard cornering loads for a much more connected, direct feeling from your car when you need it most.

The MQB/MQBE chassis use soft rubber rear subframe mounts incorporating large voids that deflect significantly under load, causing the rear end to feel vague and loose, as well as leading to less-than-optimal suspension geometry on-track.

These precision-machined billet aluminium inserts simply slide into the holes to greatly limit rear subframe movement. Installation takes just minutes, as the inserts are designed to be fitted without requiring subframe removal. Machined from billets of T6-6061 aluminium precision CNC-machined into shape, the race-proven Subframe Inserts are more than strong enough to keep your rear geometry accurately located, even on track. Unlike the polyurethane insert options on the market, these billet aluminium parts will not deform or wear over time, guaranteeing long-lasting performance.

RacingLine’s careful development process has resulted in a design that doesn’t sacrifice ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin, making this an upgrade that’s just as well-suited to a daily-driven car as a full track-prepped machine.

All of these benefits are even more pronounced on older cars with ‘tired’ rubber in the factory mounts.
