Team 5X Racing is our race team, and also the Research and Development side of our business. In addition to retail, we also prototype and test new race parts to add our touch to the racing parts marketplace. Our goal is to figure out what is needed in the grassroots road racing market, figure out an innovative product that is not already out in the market to fulfill the needs of the racing community, prototype and build the part, test in our our race cars, produce the parts, then sell them to you on our website. All done in house, excellent quality, proven on the track and street by us on our own race cars and street based test mules.
