Overview

The Canadian Auto Performance Rear Subframe Mount Insert Kit is a performance upgrade designed for the Audi B9 and B9.5 chassis platform. This kit aims to improve chassis stability and driving feel by reducing unwanted subframe movement. It is constructed from durable billet aluminum and is CNC-machined for precision fit and longevity.

Show original supplier description

The Canadian Auto Performance Rear Subframe Mount Insert Kit is engineered to enhance the handling and performance of your Audi, specifically for the B9 and B9.5 chassis. This kit addresses excessive subframe movement caused by factory rubber mounts, which can lead to a disconnected rear-end feel during cornering, acceleration, or throttle changes. By eliminating this flex, the kit provides a tighter, more responsive driving experience. This method effectively minimizes movement without requiring the replacement of OEM bushings, thus preserving the factory ride comfort and avoiding additional noise, vibration, or harshness (NVH). It is presented as a significant upgrade for enthusiasts seeking improved chassis stability and driver confidence for both spirited street driving and daily use. The kit is compatible with a range of Audi models including the A4 (B9/B9.5) from 2017–2023, S4 (B9/B9.5) from 2018–2023, A5 (B9/B9.5) from 2018–2023, S5 (B9/B9.5) from 2018–2023, RS5 (B9/B9.5) from 2018–2023, and Allroad (B9/B9.5) from 2017–2023.
