Justin Bonsignore, a 36-year-old driver from Wading River, New York, is a four-time NASCAR Whelen Modified Tour championship driver for Kenneth Massa Motorsports.
Bonsignore won his first title in 2018, on the strength of eight wins in 16 tour races, followed by a second title in 2020, then a third in four years in 2021. In 2024, Bonsignore captured his fourth title on the strength of five wins in 16 Tour events.
Over the last 15 years of racing on the Tour, Bonsignore has won 45 races with the No. 51 team and has elevated himself to second all-time on the Whelen Modified Tour wins list.
Bonsignore made his ARCA Menards Series debut with Rette Jones Racing at Daytona International Speedway, qualifying 6th and running inside the top-10 before a mechanical failure in February of 2024. He followed that up with his NASCAR Xfinity Series debut at New Hampshire Motor Speedway with Joe Gibbs Racing in June at New Hampshire Motor Speedway, running in the top-five for a long portion of the race.
In the middle of the COVID-19 pandemic (2020), Bonsignore's team went to Victory Lane in three out of nine races en route to his second crown. In 2021, the team won twice, also scoring 11 top-five finishes and 12 top-10 runs. Justin also won five pole awards in the 14 series events.
But Bonsignore's been involved in racing for his entire life. Beginning at just 8-years-old, he started racing go-karts. His family-owned and operated a kart racing shop & this early exposure to the racing circuit paved the way for a career in racing. In 2005, Justin made the jump to stock-car racing, competing at Riverhead Raceway, where he finished third in the points and was named the Rookie of the Year in the Charger division.
In 2006 his career in NASCAR Modified’s began at Riverhead Raceway in a family-owned operation with a move to the NASCAR Whelen Modified Tour full-time in 2010 with Kenneth Massa Motorsports, where he has remained the driver for 11 seasons. That is the longest current owner/driver pairing on the NWMT. In the past Justin has been an advocate and spokesperson for many great companies, as well as involved with the North Shore Animal League of America, and the United Spinal Association to raise awareness.
