Welcome to Stewart Motorsports

Slade Stewart
On the box
Family, creativity, joy

I’m not your average race car driver. I’m a competitor, a builder of teams, and a family man who brings personality and passion into everything I do. I’m best known for piloting the Lamborghini Super Trofeo car, "Sparklefarts," a machine that’s become as much about identity as it is about performance. I’m also excited to be stepping into a new chapter with the BMW M4 GT3 race car and Riley Motorsports, my new team, as I continue to grow and evolve as a driver. With its bold, fan-loved livery designed by my daughter, Sparklefarts represents more than just a race car. It’s a rolling expression of family, creativity, and joy in a sport often defined by precision and pressure.

Behind the wheel, I find clarity and calm before the chaos of competition. Outside the car, I bring that same mindset to my business, where I’m deeply focused on building high-quality teams and setting them free to excel. I’m driven by innovation, storytelling, and connection, both on and off the track. For me, racing isn’t just about results; it’s about bringing something personal to the experience and sharing that journey with others. Sparklefarts, the BMW M4 GT3, and the teams around me are all part of a journey that is fiercely competitive, deeply personal, and always evolving.
