Description
Upgrade the handling and performance of your Audi with the Canadian Auto Performance Rear Subframe Mount Insert Kit, designed for the B9 and B9.5 chassis platform. Whether you’re pushing your car hard on twisty backroads or just want a more planted, confident driving experience, this kit delivers exceptional improvement in chassis stability with no compromise in ride quality.
Audi’s factory rubber rear subframe mounts are designed for comfort, but they allow excessive subframe movement under load. This can cause your vehicle's rear end to feel disconnected, especially during cornering, quick throttle changes, or hard acceleration. The CAP Billet Aluminum Rear Subframe Mount Insert Kit eliminates that unwanted flex, resulting in a tighter, more responsive feel that enhances both performance and driver confidence.
Precision-engineered from durable billet aluminum, these inserts slide into the voids of the factory subframe mounts, effectively filling the gaps and minimizing movement. Unlike full solid mounts, these inserts retain the factory bushings, meaning you get the benefits of a firmer, more composed chassis without adding harshness or vibration to your ride.
Perfect for spirited street driving and daily use alike, this is one of the best bang-for-your-buck upgrades available for your Audi.
