Between 1998 and 2002, Wallace raced in INEX Bandoleros. He captured multiple series championships. Steve raced in Legends cars and late model racecars near his hometown of Mooresville, North Carolina. He won both the Summer Shootout (twice) and Winter Shootout (once) at Lowe's Motor Speedway. He also won multiple championships at Concord Motor Speedway. In December 2004, at the age of 17, he won one of the biggest short track races in the country, the Snowball Derby, in Pensacola, Florida, a race Rusty and Kenny both entered, but failed to win in their careers. Steve was also the 2004 UARA Rookie of The Year. He won the first ever late model race at Bristol Motor Speedway.
In 2005, he ran nearly the entire season in USAR Hooters Pro Cup competition. He finished with 3 Top 10 finishes and qualified for the post-season championship series. A day after Steve turned 18, he became the youngest winner at a Michigan International Speedway event in an ARCA race while driving a Penske RacingDodge. He raced in ARCA with several other teams that season. He also finished 15th in his first NASCARNationwide Series race at Memphis Motorsports Park (after starting 11th). Wallace became part of the Dodge factory driver development program.
His first career top five came at Richmond International Raceway on May 2, 2008.
At the beginning of the 2012 season, he was without a car because of the temporary closure of Rusty Wallace Racing. After missing the first six races, he announced that he would make his first start of the season at Richmond International Speedway during the Virginia 529 College Savings 250.[3]
Sprint Cup Series
Wallace made his sole Cup Series start in the 2011 Daytona 500. Penske Racing transferred the owner points of his No. 77, whose 30th-place finish in 2010 guaranteed Wallace a start. He drove the No. 77 Toyota to a 20th-place finish.
After his NASCAR career ended, Wallace began racing super late model race cars. At a CARS Tour-sanctioned race at Fairgrounds Speedway in 2018, Wallace was parked early in the race for wrecking Mason Mingus and later fought with Mingus and his Wauters Motorsports team. After the fight, Wallace said that the incident was one worthy of the beginning of a war.[5]
