Clayton Williams is an entry-level professional racing in national multiclass endurance and sprint series in the United States. He is FIA Silver graded, positioning him as a developing driver within GT and endurance racing. Williams drives for LAP Motorsports in IMSA Pilot Challenge and GT4 America, racing GT4-level production sports cars and touring cars in shared-driver endurance events. His primary platform over his career has been Spec Miata racing in NASA's solo sprint series.[1]
Since 2019, Williams has compiled 103 starts across four series with three wins and 26 podiums. He spent his first three seasons building experience in NASA's multiclass Spec Miata field, taking two wins and thirteen podiums in 65 starts through 2024. In 2023 he contested TC America, where he won once and took twelve podiums in fifteen starts for MINI JCW Team, establishing himself as a consistent front-runner in that series. His move to IMSA Pilot Challenge in 2024 brought him into shared-driver GT4 endurance racing, where he has competed across 19 starts to date. His current activity includes early-season appearances in GT4 America's multiclass endurance championship.[2]
Williams' record against regular opponents in NASA shows him typically finishing ahead of developing competitors with similar experience; he is the stronger driver in those matchups. He has beaten established professionals in isolated instances, including an endurance-racing result over Philip Ellis, a three-time IMSA WeatherTech GTD champion and Gold-graded driver, and a single result against Sammy Smith, a two-time ARCA champion who runs at established professional level.
