Carbon Fiber Aerodynamic Components

After 3 years of constant painstaking research and development Racing Sport Concepts is proud to launch its new line of carbon fiber aerodynamic components for the next generation of high-performance automobile enthusiasts.

What you are looking at is not just a set of side skirts but a revolution in the aftermarket automotive industry. For the last three years we have tested every piece of technology, CAD software, autoclaves, material vendors, painters, paint suppliers, aerodynamics experts, race car drivers, IMSA & Indycar crew chiefs, OEM engineers, everything possible to design the best possible product possible. These side skirts and their sister products are the culmination of that work.

Highly Accurate CFD Simulations

We started by scanning the 991.2 GT3 and building our CFD model to match real world experience on the 911 platform by using aerodynamics experts that developed highly accurate CFD simulations from working for dozens of 911 cup car teams. With our baseline accuracy significantly higher than if we had to develop a model from scratch and validate it all ourselves, while saving hundreds in thousands in development, we began to refine our design in the virtual wind tunnel.

Using dozens of simulations and design iterations to revise our designs to increase aerodynamic efficiency. It's true that almost all of our competitors prefer hand holding to digital CAD because it's faster and easier than the software route, but this would limit our ability to make changes based on the CFD results. It would also limit our ability to ensure quality control by losing the ability to scan and inspect parts at the factory to ensure quality control in perpetuity.

Superior Materials

After locking in our design we fabricated highly accurate tooling by once again leveraging our ability to use the raw CAD data to mill out tooling out of superior materials that cannot be used to "splash molds" of a hand molded part with no CAD data. Our advanced carbon fiber tooling has the exact same coefficient of expansion as the part material which provides for extremely smooth surface quality that is unmatched industry wide.

After a part has cured in the autoclave we use a ultra premium german made CNC mill to trim each part identically to the next instead of trimming by hand as most other manufacturers or brands do. Our trim fixture is more expensive than most competitors entire tool cost.

utmost quality
OEM Certified Paint

Finally after trimming we transport our skirts to 1 of less than 100 OEM certified paint shops that have the ability to use a true OEM clear coat process that is identical to that used on new cars leaving the factory. This final step includes 4-8 coats of paint to reach a paint thickness spec within 3-4 microns of our target depth. As a result this clear coat will not become milky or hazy as seen with cheaper aftermarket alternatives. In addition, this gloss coating has the most advanced UV inhibitors commercially available to OEM suppliers, many not available to non-factory certified body shops.

By ensuring this final step is of the utmost quality we can ensure that your investment will retain its value for decades not year or months. Purchasing a part of this quality is a long term investment that can be re-sold for a large percentage of the original purchase price due to the quality of the materials and longevity that they provide.

Highspeed Aerodynamik

Beim Trackday mit SSR Performance auf dem Hockenheimring war mein 991.2 GT3 einer der schnellsten ich habe jedoch die Steifigkeit wesentlich verbessert um bei hoher Geschwindigkeit keine Verformung zu haben V/max 328km/h für Show und Street ist der Frontsplitter perfekt und schnell montierbar.

The perfect final touch for your GT3

Really accentuates the side of the car and makes it look wider and lower

Purchased some side skirts and quality is off the charts! Install was very easy and Bill even took the time to chat with me on the phone about a couple questions I had. Incredible product and equally strong customer service.
