Unitronic® is proud to launch its Dogbone Mount Upgrade for the 2022+ (8Y) Audi® RS 3® equipped with the 2.5TFSI EVO (DHXA) engine and DQ500 transmission. This Dogbone Mount Upgrade, also referred to as the Pendulum Mount, was engineered to maximize performance through eliminating the slop present in the factory style mount and improving drivetrain stability to ensure the system is better suited to withstand the forces present during hard launches or demanding driving scenarios on the drag strip or race track, virtually eliminating wheel hop, and offering more crisp shifts, all while maintaining a reduced NVH (noise/vibration/harshness) for comfortable operation.
At Unitronic, few things excite us more than getting our hands on the latest crop of VAG performance vehicles and the 8Y RS 3 was no exception. Sporting an all-new torque vectoring rear diff, fine tuned suspension, aggressive new styling and improved driving ergonomics, the 8Y RS 3 is one of best balanced cars we’ve had the chance to experience here lately and we look forward to building upon this great foundation with many upcoming Unitronic Performance Upgrades.
Even though there are many similarities between the 8V.2 / 8S and 8Y platforms, there are also many differences and it was important for the team of Unitronic Engineers to thoroughly analyze, scan and cross-validate all new and existing components on our 8Y RS 3 development vehicle in order to provide the same high level of precise fitment Unitronic is known for.
Consistent with all of its performance products, Unitronic utilizes only the latest industry leading tools, equipment and computer aided design software that are packed with the latest technology from our technology partners at Creaform® and Stratasys®. Operations start with 3D scanning the 8Y RS 3 subframe, engine, transmission, and OEM components with its in-house 3D scanner. Once 3D scan data has been collected and processed, Unitronic Hardware Engineers then interact with the 3D models to identify fitment constraints, mounting locations, other component locations, etc. to ensure the final product fits perfectly within the “envelope”.
Throughout the research and development phase of this Unitronic Dogbone Mount, it was quickly apparent that new CNC machined end caps would need to be designed for the 8Y RS 3 in order to provide the best performance without any chassis interference. It was also important for us to retain the modular system which was very popular for the 8V.2 / 8S platforms, allowing customers to choose between two different inserts in order to suit varying driving styles.
Our yellow “street” poly bushings are ideal for street use, spirited driving, and the occasional track day. For race oriented builds, high power, and track-only type vehicles, our red “race” poly bushings are most ideal. Green bushings will soon be available for various MQB/MQB EVO 4-cylinder applications as well.
Unitronic’s Dogbone Arm and Endcaps are 5-axis CNC machined from T7075 billet Aluminum; and feature a black anodized finish. Unique to Unitronic’s design, are CNC machined Nylon inserts, which isolate them from the subframe to mitigate possible damage from extenuating heat radiated from the exhaust system. In addition, they facilitate an easier straight forward installation that allows the installer to install the mount on the vehicle without having to disassemble the subframe.
Finally, and most importantly, Unitronic opted to use polyurethane for its bushings due to its excellent damping and rebound properties. Polyurethane is known to withstand cyclic loading under varying operating conditions that contribute to its durability.
