The 034Motorsport Billet Aluminum MQB Rear Subframe Mount Inserts for MkVII Volkswagen Golf R, 8V/8V.5 Audi A3/S3/RS3, & MkIII Audi TT/TTS/TTRS are designed to limit movement in the factory rear subframe mounts to maintain proper suspension geometry when cornering, and improve the responsiveness of the rear suspension and differential.

By filling small voids in the four factory mounts as well as limiting vertical movement, this insert set eliminates the associated slop to ensure that you experience a more refined, connected driving experience, especially when driving at the limit. These billet aluminum parts will not pack and wear over time, and offer a lasting performance improvement.

Please Note: The factory rear subframe bolts are torque-to-yield bolts, and we recommend replacing them when installing these inserts. A new set of four OEM bolts is available separately below.

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5T EA855 EVO (Gen 2) engine!

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 2.5T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Optional features, such as APR's EMCS Program Switching and APR Mobile are available. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

The USP Motorsports High Flow RS3 & TTRS downpipe transcends expectations in quality, performance, and sound. This system has been through extensive testing and is finally ready for its release. With an astounding growl, this downpipe is sure to turn some heads as your RS3 or TTRS cruises or rips down the road. If that wasn't enough, you can also expect a gain of 25+ wheel horsepower. Our stainless steel, mandrel bent, high flow design provides the supersonic airflow, increasing throttle response and overall power increase. No exhaust restrictions mean no wasted potential. Starting from a 96mm (3.79") opening, this system transitions down to a 3" section, through a 5" High-Flow 200-cell catalytic converter and splits off into dual 2.5" straight sections that connect directly to your factory exhaust. This system has been tested on multiple 9 second, 700+ WHP RS3 and TTRS cars. It sounds incredible, optimal performance and as always backed by our lifetime warranty.

034Motorsport's Motorsport StreetSport Mounts for Audi 8S TTRS and 8V.5 RS3 models are the new standard in ultra-high performance. These mounts are designed with extreme performance in mind, manufactured from billet aluminum and high-durometer rubber, making them virtually indestructible, while maintaining better ride characteristics than polyurethane alternatives. These mounts have a lifetime guarantee regardless of power level applied and type of application they are used for.

These heavy-duty mounts will result in a moderate increase in noise, vibration, and harshness (NVH) transfer into the cabin, as they are designed to drastically reduce engine movement compared to the factory parts, but will introduce less NVH than our TrackSport mounts due to the lower-durometer rubber used. Additional NVH is most noticeable at idle, but once the vehicle is moving, NVH is
