TTAC Creator Bozidar “Bozi” Tatarević is a Bosnian-American racing mechanic, writer, and technical consultant born in Sarajevo in 1986. After immigrating to the U.S. in 1995, he learned English in elementary school and eventually turned his passion for cars—fostered by his father Slav—into a full-time career. Laid off from a tech job in 2008, Bozi began wrenching professionally, eventually launching a shop and car export business with his family. His technical message board posts led to a writing career with outlets like TTAC, Motorsport.com, Road & Track and Racecar Engineering. In 2018, he made his pro mechanic debut at Watkins Glen and now works as a tire carrier and mechanic for Vasser Sullivan Racing in IMSA, with 10 wins and a 2023 GTD Pro title. Bozi also consults via his agency Podium Prime, with clients ranging from race teams to media production companies.
