William J. Lambros Bio
William J. Lambros (born May 6, 2003) is an American professional stock car racing driver. He last competed part-time in the NASCAR Craftsman Truck Series, driving the No. 2 Ford F-150 for Reaume Brothers Racing. A versatile racer with experience across open-wheel, sports car, and stock car disciplines, Lambros began his motorsport journey as a young child and steadily progressed through developmental series before reaching one of NASCAR’s national touring divisions.
Early Life and Background
William J. Lambros was born on May 6, 2003, in Montauk, New York. Growing up in a coastal community on the eastern tip of Long Island, he was introduced to motorsports at an early age. The local racing culture of the Northeast, combined with family support, helped shape his early interest in competitive driving.
Lambros first climbed into a race car at the age of five, competing in go-karts. He continued developing his skills on karting circuits and won his first karting championship at the age of thirteen. That early success gave him the confidence to pursue a more formal path in motorsports, including earning his racing license after completing the Skip Barber 3-Day Racing School and 2-Day Advanced Racing School. In 2018, he joined the Skip Barber Driver Development program, a respected pipeline for young drivers aiming to move into professional racing.
Path to NASCAR
Following his time with the Skip Barber program, Lambros expanded his résumé by competing in a wide range of series. He raced in the Formula 4 United States Championship, the TC America Series, and the Michelin Pilot Challenge, gaining experience in open-wheel and sports car machinery. He also competed on oval and paved short tracks in the SMART Modified Tour and the Monaco Modified Tri-Track Series, two of the Northeast’s prominent touring series for modified race cars.
This variety of cars and track types helped Lambros become a well-rounded driver. His ability to adapt from open-wheel cars to modified stock cars positioned him for a step up to NASCAR’s national level. In 2025, it was confirmed that Lambros would make his NASCAR Craftsman Truck Series debut, a significant milestone in his young career and his first entry into a NASCAR national touring series.
William J. Lambros Career
Early Career (2018–2024)
Lambros’s formal development began in 2018 when he entered the Skip Barber Driver Development program. The program provided structured training and exposure to professional racing environments, giving him a foundation in race craft, vehicle dynamics, and competition strategy. During this period, he balanced training with active competition in karting and entry-level open-wheel championships.
As he matured as a driver, Lambros moved into car racing, debuting in the Formula 4 United States Championship. The series allowed him to compete on a mix of road courses and street circuits, building his resume with established junior teams. He also gained valuable seat time in sports car racing through the Michelin Pilot Challenge and in touring car competition through the TC America Series, rounding out his experience in door-to-door racing.
SMART Modified Tour and Tri-Track Breakthrough (2020s)
Returning to his Northeast roots, Lambros competed in the SMART Modified Tour and the Monaco Modified Tri-Track Series. These modified racing series are known for their close, physical competition and serve as proving grounds for aspiring NASCAR talent. Running on short tracks and larger ovals, Lambros developed the kind of race-day awareness and mechanical sympathy that modified racing demands.
The transition from open-wheel and sports car machinery to modified stock cars was an important step in his development. Modified racing prepared him for the heavier, more powerful cars used in NASCAR’s national series and helped him build a competitive record in regional competition.
Reaume Brothers Racing Era (2025)
In 2025, it was revealed that Lambros would make his NASCAR Craftsman Truck Series debut at Lime Rock Park, driving the No. 2 Ford F-150 for Reaume Brothers Racing. Lime Rock, a road course in Connecticut, was a fitting venue for a driver with strong road-racing experience. Lambros’s first Truck Series start came in the 2025 LiUNA! 150 at Lime Rock, marking his official entry into NASCAR’s national ranks.
He made a second Truck Series start later in the summer at Watkins Glen International in the 2025 Mission 176 at The Glen. Both appearances showcased his comfort on road courses, a track type where his diverse background offered a clear advantage. His part-time schedule reflected both the developmental nature of his program and Reaume Brothers Racing’s approach to giving young drivers opportunities.
