One day in January, the 21-year-old USAC midget racer checked a printed schedule that all of Toyota Racing’s development drivers received. “He knows so much about the race car,” Harvick said. At the dawn of Busch’s car, he was teammates with Martin at Roush Racing from 2000-’05. Busch leaned on Martin for advice while finding his way in the sport. “Mark Martin is the guy I trusted the most and it was a blessing to race with him and to have him as a teammate,” Busch said in March at Circuit of The Americas. “There’s the highs and highs, there’s the lows and lows,” Busch said. Wheeler said he wasn’t ready for, and was surprised by the results, of how Busch helped his new teammate.
