A sight to behold and a joy to drive, it’s easy to understand why the Mazda Miata is the best-selling roadster of all time. Offering exceptional handling and a tenacity that belies its classic appearance, the ND Miata has spawned legions of enthusiasts, clubs, and racing series nationally and worldwide. 

If your street Miata has track aspirations, or if you simply want more performance for your daily drive, Verus Engineering has your solution. Our downforce-generating rear diffuser and suspension covers can improve your stability and performance at higher speeds. See how they will benefit you.

Reduce Drag And Lift With One Well-Designed Component

Extracting more performance from an already lively roadster requires a skilled hand. Enter the team at Verus Engineering. Using one of our favorite tools – state-of-the-art computational fluid dynamics (CFD) software – we were able to design a rear diffuser that checks all the boxes. You get the following:

  • Reduced drag
  • Reduced lift (more downforce)
  • Improved overall aerodynamic efficiency (increase L/D)
  • More tire grip at speed
  • Improved gas mileage for daily drivers

How Do The ND Miata Diffuser And Suspension Covers Work?

Verus Engineering's suspension covers help provide clean, uninterrupted airflow to the diffuser.

Verus Engineering’s rear diffuser creates a low-pressure zone under the car. The subtle, expertly designed strakes help promote this area of faster-moving air by generating vortices that keep flow attached to the diffuser’s surface. By directing air into the wake region behind the vehicle, drag is minimized. Suspension covers aid this process by reducing areas of turbulence and feeding the diffuser clean, uninterrupted air. Essentially, they help your diffuser perform.

Verus Is Your Top Choice For ND Miata Mods

Verus designs are informed by scan data, CFD software, and general engineering best practices to create solutions that go beyond just adding downforce. We strive for aerodynamic balance and predictable performance in everything we do, and recommend our complete aero kits to get the best experience possible.

Driven to design parts that help your vehicle perform, Verus also prioritizes fitment and crafts components that look like OEM. We understand that you want both form and function, and our 3D scans enable us to create components that not only match the aesthetic but also enhance it. As a cherry on top, the diffuser attaches easily in a non-invasive bolt-on installation. Note that the diffuser must be installed when using our suspension covers.
