TGK Motorsport Rear Subframe Mount Billet Insert Kit – D4

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.

Key Features:

1. Enhanced Performance: These billet inserts are engineered to stiffen the subframe, ensuring minimal movement and maximum efficiency during dynamic driving conditions.
2. Optimized Comfort: Unlike fully solid mounts, our billet inserts maintain the comfort of your ride by not adding any noticeable NVH (Noise, Vibration, and Harshness).
3. Premium Quality: Made from high-grade materials, these inserts are designed for durability and long-lasting performance.
4. Easy Integration: The kit is designed to complement the OEM bushings, making installation straightforward without the need for extensive modifications.
5. Versatility: Ideal for a wide range of modern sports cars, the kit serves as an intermediate upgrade before transitioning to completely solid mounts.
6. Future Upgrade Path: This kit is a precursor to our fully solid subframe mounts, providing a scalable upgrade path for your vehicle.

It is advised to REPLACE the stretch bolts that hold the subframe in place, they are a multi-use bolt, but CAN stretch, or even bend like ours were.  We can supply them if you want them or you can source them from Audi:
