034Motorsport is proud to offer our Billet Aluminum Drivetrain Mount Insert Package for the B8 Audi A4/S4/RS4, A5/S5/RS5, and Q5/SQ5! The factory Audi transmission and rear differential mounts have large voids in the rubber damping medium, which results in excessive drivetrain movement under load. This movement results in slop than can be observed when accelerating, decelerating, shifting, and launching.

These billet aluminum inserts are designed to fill the large voids in the factory transmission and rear differential mounts, and limit drivetrain movement without sacrificing ride quality or introducing any additional noise, vibration, or harshness into the cabin. By filling the voids in the factory mounts, this package eliminates the associated slop to ensure that you experience crisper shifts, harder launches, and a smoother driving experience.

This mount insert package was thoroughly tested by 034Motorsport, JH Motorsports, and independent Audi enthusiasts before release. Installation is very simple, can be performed in minutes, and is completely reversible.

T6-6061 Billet Aluminum Construction

CNC-Machined In-House

Engineered to Fill Voids In Factory Transmission/Differential Mounts

Drastically Reduces Transmission & Differential Movement During Shifting & Deceleration

034Motorsport is proud to offer our Billet Aluminum X-Brace Chassis Reinforcement Upgrade for the B8 & B8.5 Audi A4/S4/RS4, A5/S5/RS5, and Q5/SQ5! The factory Audi front subframe brace is manufactured from multiple pieces of stamped steel, and allows for performance-hindering chassis flex under load. This torsional flex can result in improper suspension geometry and alignment when cornering, and leads to vague steering feel and lack of steering precision.

The 034Motorsport X-Brace is a billet aluminum chassis reinforcement to replace the factory front subframe brace to increase torsional rigidity, resulting in improved steering feel and handling performance. Machined in-house from T6-6061 billet aluminum, the 034Motorsport X-Brace is engineered to outperform the stock welded, stamped steel part and ensure that suspension geometry is not compromised by chassis flex under hard cornering.

This chassis brace upgrade was thoroughly tested by 034Motorsport and independent Audi enthusiasts before release. Installation is very simple, can be performed in minutes, and is completely reversible.
