More power is always on the wish list. Is cooling? 🤔

When you’re planning your next NA Miata upgrade, give heat management a place in the budget. Our hood vents offer a practical way to help hot air escape, with configurations that let you choose how far you want to go.😎

We recommend all five when cooling is the priority.

This is not a Miata BUT 😎😮‍💨

We’ve never made a Turbo Disco for a 26-inch wheel. So when a customer asked for a set for his Cybertruck, we got to work.

First up: scan the wheel, check the dimensions, and work out how everything will mount. The 3D scan gives us the geometry to start designing around the actual wheel.

Still early in the process. More on this build soon.

Engineered to make airflow work for your Miata. 🏁

RGR Aero Side Skirts use underskirt airfoils to help redirect airflow around the tires, reduce drag, and increase downforce. Developed through engineering, testing, and CFD analysis, they work alongside your RGR splitter and diffuser for a more efficient aero setup.

Carbon fiber. Precision-machined components. Installation using existing mounting points.

For the past couple of weeks we have been very succesfully testing our upcoming NC Chassis Mounted Splitter.

This kit offers the same benefits as our existing NA/NB offerings.

Bolt-on and adjustable, it is designed to be used with and without lips. No cutting required and very easy to install.

This kit comes standard with ramps, it does not requires front rods, and has threaded inserts on the chassis brackets to allow for easy installation and removal.

Let us know your thoughts!

More Turbodisco options. Better details. 😎

CNC-machined inserts, stainless hardware, 7075 forged aluminum lug nuts, and new fitments for 15x7 RPF1 4x100 and 17x9 RPF1 5x114.3.

Small updates that make a big difference.

The next evolution of the Tipo UNO Aero Kit.

The new RGR Flat Floor for NA & NB Miatas completes the Tipo 2 package, with the goal or farrying clean airflow from the front splitter all the way to the rear diffuser for susbtantial downforce gains.

CFD results and testing so far have been promising. But we are still looking to further our real-world testing, especially under higher-power and harsher conditions.

Aero that actually does something. 😮‍💨😎

The RGR Aero Side Skirts for NA & NB Miatas were developed through engineering, testing, and CFD analysis to improve airflow around the car.

The carbon fiber blade, underskirt airfoils, and wickers work together to reduce drag, manage airflow around the tires, and improve aerodynamic efficiency when paired with a front splitter and rear diffuser.

Made from carbon fiber, billet aluminum, Delrin, and powder-coated aluminum, these side skirts are built for performance and easy installation using existing mounting points.
