V3 Rear Diffuser Kit for Miata MX-5 NA & NB/NBFL (1990-2005)

Introducing the R Theory Motorsports V3 Miata Rear Diffuser, now available. It’s crafted with the straightforward and functional aesthetics of the V1 in mind, while also integrating a curved profile akin to the V2. It stands taller and presents a more aggressive stance compared to its predecessor.

The key benefit of a curved diffuser design, as opposed to a traditional wedge shape, lies in its ability to enhance surface attachment. In simpler, this design allows air to more efficiently follow the upward incline of the diffuser, generating a low-pressure area beneath the vehicle. This low pressure is essential for producing downforce.

Each V3 Mazda MX-5 Miata Diffuser features a Matte Black Powder coated finish. The latest Gen 3 V3 diffusers are now fully welded, eliminating the need for assembly and arriving ready for installation on your Miata. This welded construction not only enhances the aesthetic appeal but also improves airflow compared to the previous bolted design.
