Motorsport aerodynamics for your BMW M4 F82!

With our SPEED diffuser, you not only stand out from the crowd visually, but also transfer technology from professional racing to your car. The ratio between air resistance, which you want to keep as low as possible, and the downforce you want is maximized with this concept.

The difference: This is not a component attached to the rear bumper. Most vehicles have a hollow space in the rear area. This space leads to a turbulent flow situation. With our diffuser, we cover as much of it as possible and ensure that the air flow remains as laminar as possible. Because it is made of aluminum, the diffuser is light and stable at the same time and remains affordable.

The assembly is well thought out: We use the original screwing points wherever possible. This means that nothing needs to be cut into your vehicle! In rare cases, an additional hole is drilled. The connection is made using as many connection points as possible so that we have an even distribution of force across the entire diffuser board.

TÜV and registration

We spared no expense and effort and had the diffuser examined by experts: Your diffuser comes with a parts certificate and can therefore be registered without any problems! Attaching the edge protection provided is necessary for approval.

Please note: Each of our diffusers was deliberately developed with base vehicles that already have a coilover suspension with a low setup. This ensures a ground clearance of 8 cm including the mounted diffuser. However, we cannot reproduce every setup. In this case, the development vehicle had an exhaust system from Akrapovic. It can be assumed that most aftermarket exhaust systems are compatible with our diffuser. The original BMW exhaust system is definitely not compatible . If your vehicle has a different exhaust system or a modified rear bumper, you may have to adapt and modify your diffuser.
