Since 1974, Arizona Sport Shirts has been the trusted choice for race teams looking to elevate their brand and connect with fans.

  • Founded by Karl Korbacher in 1974.

  • Korbacher was a photographer who had the idea of putting race photos on t-shirts instead of selling photos. The name started as Photos by Karl, later Arizona Sport Photos which then became Arizona Sport Shirts, This led to the creation of the first racing t-shirt.

  • The business began in a small garage in south Phoenix, Arizona on the grounds of the famous Manzanita Speedway. In 1984 Karl marries Cheryl Borgsmiller and the 2 start on a journey that led them to Indianapolis.

  • In 1989, the company moved to Indianapolis, Indiana, due to the city's central location for many dirt tracks. This is when Karl meets Gerald Newton and he remains today.

  • In 1995, Arizona Sport Shirts launched its own clothing line called Gotta Race.

  • The company's long-standing slogan, "TheOriginalRacingShirt®"
