D3|Motorsport Labs

The D3 Motorsport Lab is our 10,000 square foot facility in which we research, design, manufacture and distribute our tuner program to our worldwide audience.


At D3 we are proud of both our quality and craftsmanship. Our products are manufactured to the highest standards of quality and proudly made in America. Our in house product development team individually blueprints most if not all of our products before even the first prototype part is manufactured. This ensures 100% capability and maximizes performance down to the smallest detail. No product is brought to the market without first surviving our rigorous and meticulous testing procedures. Additionally whenever possible we send our products out for 3rd party quality control to be further tested and approved for proper operating compliance.


Our manufacturing procedures call for only utilizing the highest quality materials such as USA made Billet Aluminum, Vacuum Infusion Carbon Fiber Manufacturing, Reaction Injection Molded Plastics, and Precision CNC machined parts to name a few.

With our extensive experience from decades of involvement in the highly competitive and rigorous motorsport industry D3 has become the driving force in the aftermarket manufacturing and has become well known within the manufacturing side of the tuner markets.

D3 is capable of developing Motorsport Products from conception, to rapid prototyping, to final assembly. Our product lines are available for both direct and distribution sale.
