USCA #231: Lightweight Wins—How Dayton de la Houssaye Makes a Miata Outrun the Competition

This week on the Ultimate Streetcar Podcast, Jimmy and I continue our Summer Interview Series with one of the brightest young stars in the Ultimate Streetcar Association, Dayton de la Houssaye of GeauxMoto. At just 23 years old, Dayton has already become one of the fastest drivers in the series, consistently putting his EcoBoost-powered Miata at the very top of the time sheets—even against much larger, more powerful competition. What makes Dayton's story so interesting isn't just the speed. We talk about growing up in Louisiana riding dirt bikes and racing four-wheelers before transitioning into cars, how GeauxMoto evolved from building lifted rally Miatas into an engineering and fabrication company designing custom performance parts, and why lightweight cars continue to outperform expectations. Dayton explains why learning to drive a lower-horsepower car makes you a better driver, how aerodynamics completely transformed the handling of his Miata, and why engineering and driver development often matter more than simply adding horsepower. The conversation also dives into GeauxMoto's latest projects, including EcoBoost conversions, custom carbon fiber aero components, and an ambitious K24-powered Porsche build that is sure to turn heads when it debuts. Along the way, Dayton shares why Ultimate Streetcar remains one of his favorite series to compete in, the friendships and family atmosphere that keep him coming back, and the healthy competition that continues to push him to become a better driver every season. More than anything, this episode is a reminder that the future of performance driving is in good hands. Dayton brings an enthusiasm, humility, and passion for motorsports that is contagious, making this one of the most enjoyable conversations we've had all summer. Whether you're a Miata fan, an engineering enthusiast, or simply love hearing how talented young racers are changing the landscape of street car competition, you're going to enjoy this one. Source
