1970
RUFFIAN MUSTANG
BUILD OVERVIEW: The Mustang was built as a race car that I could drive to work on Fridays. It was inspired by the Trans Am race cars of the late 60s and early 70s and debuted at SEMA 2019 in Toyo's Treadpass booth. It can now be found stalking the streets, car cruises, and autocross events of Southern California.
