Most people see a black sprint car with the number 15k.
We see three generations of family, hard work, and memories.
Our racing story didn't begin with us. It began in the 1960s when my grandfather, Lonnie Kaiser, raced at Vallejo Speedway. He started with the number 94, but when he moved into sprint cars, he adopted the number 15k. Years later, when our family made the move into sprint cars, there was never any question what number we'd carry.
The 15k isn't just a number on the side of the car. It's our way of honoring the man who started this journey.
If you've ever looked closely at one of our race cars, you've probably noticed a bat somewhere on it. That's another tradition Grandpa Lonnie started, and we've proudly carried it onto every car since I first started racing at five years old.
Today, our team is still built the same way it always has been—family.
My dad, Kris, serves as Crew Chief. Brad keeps the car race-ready. My mom, Stacey, keeps the whole operation running and makes sure nobody leaves the pits hungry. My girlfriend, Nikki, is always there in my corner. I handle the driving along with suspension and tire setup.
Monday through Friday we're at work like everyone else. Nights are spent in the garage. Weekends are spent chasing the next checkered flag.
We don't race because it's easy. We race because it's part of who we are.
Whether you've followed us for years or you're just finding our page today, thank you for being part of the journey.
This isn't just the story of a sprint car.
It's the story of the Kaiser family.
