Peter Sospenzo

Peter Sospenzo (born December 23, 1956) is an American professional stock car racing crew chief, currently working with Premium Motorsports in the NASCAR Cup Series. He previously competed in the NASCAR Busch Grand National Series as a driver.

Career
A former NASCAR Busch Series and ARCA Permatex SuperCar Series driver, Sospenzo began working as a crew chief in 1994 with Rich Bickle. From 1994 to 1997, he worked with Phil Parsons, Joe Ruttman, Lake Speed, Loy Allen Jr., Mike Wallace, and Gary Bradberry. He later joined Penske-Kranefuss Racing, taking over as Jeremy Mayfield's crew chief during the 1999 season after Paul Andrews was fired. In 2000, Sospenzo and Mayfield won two races, though the former was also subject to penalties during the year for various infractions. In May, he was fined following Mayfield's win at California Speedway for a roof height violation, followed by a four-race suspension for using illegal fuel additives during the Talladega Superspeedway race in April.

He joined Hendrick Motorsports' No. 25, driven by Joe Nemechek late in the 2002 season. The following year, the two won at Richmond International Speedway; Nemechek rebounded from a pit miscommunication that dropped him to 25th by taking the lead late in the race and was declared the winner when the event was shortened by rain. With the Hendrick organization, Sospenzo later worked with Brian Vickers and Terry Labonte. He reunited with Nemechek at Ginn Racing in 2007, but was released when the team merged with Dale Earnhardt, Inc. in July.

After Ginn, Sospenzo joined Michael Waltrip Racing and Michael McDowell's No. 00 car, which was followed by leading Kevin Conway and David Gilliland at Front Row Motorsports. In 2014, he became Dave Blaney's crew chief at Randy Humphrey Racing. A stint at Team Xtreme Racing in 2015 saw his final race as a Cup crew chief—the 2015 Daytona 500 with Reed Sorenson—until 2018.

In 2018, Sospenzo joined Premium Motorsports; in addition to overseeing the team's No. 7, he led Stefan Parsons' NASCAR Camping World Truck Series debut with the team at Bristol Motor Speedway. The following year, he became the crew chief of Spire Motorsports' No. 77. In July, he won the rain-shortened Coke Zero Sugar 400 at Daytona with driver Justin Haley. In addition to being Haley and Spire's first Cup victories, it was Sospenzo's first since the coincidentally also-rain-shortened 2003 Richmond victory with Nemechek.
