Introduction

Racing career
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.

ARCA Racing Series
She was called by Venturini Motorsports to run a part-time schedule for them in the ARCA Series in 2018.
W Series
She 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 (along with Natalie Decker, her 2018 teammate at Venturini). Breidinger was named to be among the top-50 finalists, although she did eventually get 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 of 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.
Personal life
Breidinger and her family live in Hillsborough, California. She has a twin sister named Annie who is also a racing driver and has competed in go-karts and USAC along with Toni. She has also done some modeling.
