Early career

Breidinger began racing go-karts at the age of nine with her twin sister Annie in 2009 at Sonoma Raceway. Her father bought the sisters a go-kart after they started going to a local go-karting facility and had fun racing there. He bought one go-kart and eventually a second so each of them had their own.^[3]

ARCA and NASCAR

She was called by Venturini Motorsports to run a part-time schedule for them in the ARCA Series in 2018.^[4]

Breidinger returned to ARCA in 2021 on a part-time schedule for Young's Motorsports beginning at Daytona International Speedway.^[5] The team also announced that Breidinger would run a part-time schedule in the NASCAR Camping World Truck Series that year, driving the No. 82, a new part-time fourth truck for the team. This would have made her the first female Arab-American driver to compete in a NASCAR national series.^[5][6] Her Truck Series debut did not end up happening because she left Young's Motorsports in July to return to Venturini Motorsports, where she was announced to compete for them in 4 main ARCA Menards Series races along with the West Series season-finale at Phoenix.^[7]

Breidinger's 2024 NASCAR season kicked off with a 27th-place finish at Daytona International Speedway in the Truck Series^[8] and a 37th-place finish in the ARCA Menards series.^[9]

W Series

In 2019, Breidinger tried out for the W Series, a new racing series composed exclusively of female drivers from around the world. She first announced her intentions to become an applicant for the series in December 2018^[10] (along with Natalie Decker, her 2018 teammate at Venturini). Breidinger was named to be among the top-50 finalists,^[11] though she was eventually cut from the program.

Late models

In 2017, she ran various Late model races throughout the state of California as a teammate to Hailie Deegan.

In March 2019, Breidinger signed with GMS Racing to compete in several late model events for them. She also became part of the Drivers Edge Development program which is composed of up-and-coming drivers from both GMS and JR Motorsports.^[12]

In 2020, Breidinger competed in Carolina Pro Late Model Series, for DLP Motorsports driving the 80 car. She placed 4th in points.^[13] In the 8 races in the series she placed 3 Top 5s, and 4 Top 10s.^[13]
