Spencer Bucknum is a semi-professional driver with a Racer Rating of 3,649, placing him at the professional level of club and regional racing where he beats semi-professionals comfortably and competes regularly against drivers with factory and professional backing. His FIA categorisation is Silver, marking him as a professional-level sportscar and endurance racing driver, typically early in his career. Across four seasons from 2021 to 2025, Bucknum has started 14 races with 4 wins and 9 podiums, averaging a third-place finish.[1]
Bucknum's record centres on TC America and TC racing in 2023, where he scored three wins in six TC America starts and one win in two TC outings, both with LA Honda World Racing. His head-to-head record against his most frequent rivals tells a consistent story: he finished ahead of Devin Anderson in 7 of 10 shared races, ahead of William Lambros in 9 of 10, and swept the races against lower-rated drivers PJ Groenke, Shaoyi Che, and Cooper Broll. He has also beaten established professionals in isolated results, including a finish ahead of Gold-graded Jon Lancaster and two races each ahead of Silver-graded Ryan Shehan and Braydon Arthur, though these do not represent consistent head-to-head patterns. His early 2021 US F4 outings yielded no points and no podiums.
Bucknum has remained active in 2024 and 2025, competing in TGRNA GR Cup North America in 2024 without points and joining Flying Lizard Motorsports for a two-car McLaren Trophy America programme in 2025, where he secured one podium in two starts. His career has progressed from single-seater exposure to consistent success in one-make and touring car classes with a Honda-backed team.
