RGR NA/NB "ULTRA" SIDESKIRTS
RGR NA/NB "ULTRA" SIDESKIRTS
Ever seen a Miata side skirt with CFD analysis? Or billet aluminum hardware? A skirt validated to complement both a splitter and diffuser? Now you have.
At RGR, our goal has always been to apply our professional motorsports aerodynamic experience to the Miata platform, and these side skirts bring us closer to a comprehensive aero solution.
Design and Functionality:
Paired with RGR’s Front Splitter and Spats/Wickers, these side skirts enhance the low-pressure zones at the front and rear, optimizing airflow along the car’s length. Wider rear tires and flow separation in the front wheel well create drag, but our underskirt airfoils direct air past the front and rear tires, helping "seal" the car's midsection. This design significantly increases undercar downforce, as demonstrated in CFD testing.
Features:
- Unique underskirt airfoils: Each full-side skirt includes two, guiding airflow from the front and rear tires for reduced drag and enhanced downforce.
- 100% Made in the USA from powder-coated aluminum, billet aluminum, Delrin, and carbon fiber components.
- Bolt-on design for easy installation: Front attachment at the fender, middle bracket bolted to pinch welds, and rear mount in front of the rear tire with an integrated wicker.
Variants:
- Full Side Skirts: Includes underskirt airfoils for maximum performance.
- Base Side Skirts: Excludes underskirt airfoils.
