RGR NB Small Tupperware ''Ultra'' Aero Sideskirt

$335.00 - $385.00 Coming Soon

MXA-SK3

Have you ever seen CFD for a Miata sideskirt?

Have you ever seen billet aluminum hardware used in one?

Have you ever seen a sideskirt designed and validated to work together with a Splitter and a Diffuser for a Miata?

Now you have.

Ever since we started RGR one of our goals has been to apply our professional motorsports and automotive aerodynamic experience to create a comprehensive yet friendly aero solution for this platform. Now we are one step closer.

Installation:

Our side skirts have been designed to be functional but easy to install. They attach in the front to the existing front fender lower mounting points, in the middle by a bracket that gets bolted to the pinch welds (thus allowing access to both sides of the bolt to prevent rust creation), and in the rear to the area just in front of the rear tire with the help of the integrated rear wicker (spat). A combination of Stainless Steel hardware and double-sided tape holds the sideskirt in place.

Manufacturing:

Our sideskirts are 100% made in the USA. They employ a combination of lightweight powder-coated sheet aluminum, billet aluminum, machined Delrin, and carbon fiber elements. They are designed to be durable yet light.

The design:

With our Front Splitter and Spats we managed to greatly increase the low pressure at the front of the car, The spats also created a quasi-evacuating effect behind the front tire but flow separation in that area hindered further potential benefits. Just like in the front wider rear tires are also on the way creating extra drag.

This meant that even though the front of the car was working well when the air got to the middle of the car, it lost its low-pressure properties. Our rear diffuser helped create a 2nd low-pressure zone in the rear, but the issue remained.

The goal was to manage the air exiting the front wheel well and traveling around the car, as well as to deflect air away from the rear tire in an effort to not only reduce drag but create a difference of pressure that would help "seal" the middle of the car.

We worked hard to design and properly locate a front fin, we also designed an integrated wicker (spat) that helped a lot, but one of the best features (and one that you will only find here) of our sideskirts is our underskirt airfoils.

Each Full sideskirt gets 2 underskirt airfoils, one helps deflect the air coming from the front tire away from the car while working together with the fin, and the other airfoil deflects air away from the rear tire while working together with the rear wicker (spat).

Every single element of these sideskirts has been designed with function in mind.

All these elements resulted in a significant increase in low pressure under the car as shown in picture #4, effectively achieving the goal of "sealing" the middle of the car. This means more downforce all around.

The next step of our aero solutions will be a flat floor that we expect will increase the efficiency of every single one of our aero parts.
