Overview

Elevate your driving experience with the TGK Motorsport Rear Subframe Mount Billet Insert Kit. This kit features four precision-engineered billet inserts crafted to seamlessly fill the voids in your vehicle's OEM bushings. By reinforcing the subframe, these inserts provide a significant increase in stability and control, especially during high-performance maneuvers such as launches and spirited driving.

Unlike fully solid mounts, our billet inserts maintain the comfort of your ride by not adding any noticeable NVH (Noise, Vibration, and Harshness). Made from high-grade materials, these inserts are designed for durability and long-lasting performance while providing an easy integration with OEM bushings. This kit serves as an ideal intermediate upgrade before transitioning to completely solid mounts and provides a scalable upgrade path for your vehicle.

Frequently Asked Questions

Do I need to replace the subframe bolts during installation?

Yes, it is advised to replace the stretch bolts (WHT-005-800, WHT-004-756-A) as they can stretch or bend during removal and may not provide proper torque specifications when reused.

Will these inserts increase noise, vibration, and harshness?

No, unlike fully solid mounts, these billet inserts are designed to maintain ride comfort without adding noticeable NVH while still providing performance benefits.

How do these compare to fully solid subframe mounts?

These inserts serve as an intermediate upgrade, providing enhanced performance while maintaining comfort. They're designed as a precursor to TGK's fully solid subframe mounts for a scalable upgrade path.

What vehicles are compatible with this kit?

This kit fits 2008-2018 Audi B8/C7 platforms including A4, S4, A5, S5, Q5, SQ5, RS5, A6, S6, RS6, A7, S7, RS7, and Allroad variants.

Is professional installation required?

While the kit is designed for straightforward integration with OEM bushings, subframe work requires proper tools and torque specifications. Professional installation is recommended for optimal results.

Solid Upgrade - Get it?

This purchase was motivated by a suspicion that there was some laxity within the subframe of the Audi, specifically at the juncture where the differential and rear suspension are mounted. Despite tightening all other components, it was theorized that this would inevitably place undue stress on these four crucial mounts.

Upon evaluation, the results were remarkably positive, yielding a significant improvement. Notably, there was no perceivable increase in Noise, Vibration, and Harshness (NVH) levels. Furthermore, the acoustic profile of the vehicle when encountering bumps improved comparably to the enhancements observed with the sway bars.

The vehicle now exhibits a marked reduction in tracking road imperfections with the rear wheels. Previously, a slight "wiggle" could be felt in the rear end under certain conditions, especially when the front of the car transitioned onto perfectly flat concrete while the rear was still navigating through depressed or pitted sections of the road.

Additionally, this upgrade addressed a resonation issue that was commonly reported by owners of the S6/S7 models. This issue typically manifested at speeds at around 50 and 80 MPH, particularly after upgrading bushings with inserts or replacements. I now believe that this resonance was effectively transferred to the four mounts, which are now securely fastened. With the introduction of differential inserts, the auditory focus has shifted exclusively to the front end of the vehicle, eliminating any differential noise entirely.

This enhancement not only rectifies specific mechanical concerns but also contributes to an overall more refined driving experience.
