Lindsay Brewer achieved an early career milestone by winning the championship in the US Legend Cars series during the 2015-16 season, marking her first championship victory in car racing. This success followed her foundational years competing in national karting championships across the United States from 2009 to 2014. After enrolling in the Skip Barber Racing School, Brewer obtained her SCCA Competition License in 2015, paving the way for her transition into car racing. After a period away from the track, during which she earned a Bachelor of Science degree in Business Administration from San Diego State University in 2019, Brewer made her return to professional racing in 2021, competing in the TC America Series while driving for Skip Barber Racing School.
This move established her as the first American female to race in Indy NXT since 2007. Looking ahead, in March 2025, Brewer signed with RAFA Racing to compete in the Lamborghini Super Trofeo North America series, expanding her presence into international sports car racing. Throughout her racing career, Brewer has cultivated a significant profile as a model and brand ambassador, leveraging her robust social media presence. She actively engages in promotional work with several global brands, participating in advertising campaigns and serving as a spokesperson.
This multifaceted approach has been instrumental in securing crucial sponsorships for her racing endeavors, demonstrating her comprehensive engagement within and beyond the motorsport industry.
