aerofabb® is proud to offer a fully functional Rear Diffuser for the MK8 GTI with an innovative, durable, and replaceable strake design. The aerofabb® Competition Series Rear Diffuser main plane and forward flat floor are constructed from a light weight, precision machined 5052 Aluminum which is finished in lightly textured and durable matte black powder coat. No need to worry about bending or cracking Diffuser Strakes. Our easily replaceable/durable strake design is made from a high-impact/heat-resistant plastic. We look at this component as a “wear” item. This innovative design allows for load to be placed on the strakes if and when there is contact with the roads surface, without sacrificing durability. No need to replace an entire unit if it comes to the point of excessive “wear”.
5052 Aluminum was the choice for our CNC machined/press brake bent brackets with four of them featuring pre-installed nuts for painless installation. Stainless Steel Metric hardware is used throughout the kit to securely mount and fasten all components together.
Depending on your current exhaust set up, aerofabb® gives you height adjustability in order to accommodate most aftermarket exhausts. A visual tuft test was used during the beginning stages of development in order to confirm our base design worked and air was evacuating as it should. We then made minor but necessary changes to strake size, length, and angle (especially side planes near the rear wheels) to prevent spill over into the main plane. Using ANSYS Fluent Software for CFD (Computational Fluid Dynamics) we were able to optimize our design and further validate its functionality.
