Nemechek brought his No. 87 cars back for 2011 to once again run both major NASCAR series. Nemechek successfully qualified for the Daytona 500 for the second year in a row but was once again involved in an early incident, thus failing to finish again. On June 9 at Texas Motor Speedway, along with Jeff Burton he made his 900th NASCAR start in all top three series. In the Nationwide Series, Nemechek scored his first top five since 2005 with a 3rd-place finish at the Aaron's 312 after being in the position to win with 2 laps to go. In July, Nemechek picked up sponsorship from Extenze and AM FM Energy to run the full race in both series at Daytona International Speedway. He led laps in both races but was taken out in late accidents. Nemechek collected Nationwide Series points for 2011 under NASCAR's policy that a driver may accumulate points for only one series, and finished 14th in the final standings. He ran the No. 87 in both the Sprint Cup and Nationwide Series in 2012, with the Cup ride as a start-and-park to fund the Nationwide team. Nemechek made his 600th career start at Michigan and finished 40th after starting 37th. Nemechek finished 11th in the 2012 Nationwide Series points.
