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.

Performance Gain (RS3 with Stock Turbo): 15-18hp, 19-23ft-lb

Introducing another World first – a purpose designed carbon headlamp duct for the Audi RS3 8V.

With the RS3 gaining popularity as a serious track car, we have developed an additional part for our intake to give you that extra edge. This headlamp duct replaces the OEM headlamp and seals against our RS3 intake for a true RAM-AIR configuration with a direct cold air feed to the filter. The duct follows the same lines as the stock headlamp and features two carbon air guides to channel airflow to the filter. It also has vents on the surface which is perpendicular to the oncoming flow to prevent drag. Tested on track at speeds over 190mph we have ensured that the advantage of the air feed outweighs any additional drag for a net gain in track times. Since this duct replaces the main intake duct inside the engine bay against the slam panel – this area now remains open as a source of cooling for the engine itself. With the car in motion, external air flows into the grill and through the stock openings over the engine for an extra cooling effect. The headlamp duct allows for the most direct cold air feed possible and significantly helps to reduce heat soak keeping track times consistent.

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 APR Intercooler System is a massive front mounted upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! The system is an easy to install, direct bolt-on design, that is recommended at every stage of performance.

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.
