Reg Williams is a semi-professional racer whose 13-season career has centred on club and regional competition. His rating of 3,475 places him in the semi-professional band; this describes a driver who wins regularly in pro-am and one-make classes and typically finishes mid-pack among full professionals. Williams spent his first eight seasons in PCA Club Racing from 2014 to 2021, where he was a consistent podium finisher with 1 win and 9 podiums across 38 starts. He moved to International GT in 2022 and has since established himself as a front-runner in that series, recording 20 wins and 33 podiums in 36 starts. His average finishing position across all 74 starts stands at 3.5, reflecting a career built on high podium frequency rather than outright dominance.[1]
Williams has competed most extensively against Tom Pank, a three-time International GT GT4.R champion, and the pair have split their head-to-head record evenly at 14 wins apiece across 28 shared races. Against weaker fields and lower-rated drivers, Williams has built a strong pattern; he finished ahead of Juan Gonzalez in 18 of 23 shared races and ahead of Stuart Fain in 11 of 12. He has shown occasional capability against established professionals, with isolated victories over drivers rated substantially higher: FIA Silver graded drivers Michai Stephens and Mike Skeen, the latter a former Trans-Am TA2 champion. These results remain single instances against drivers from stronger fields, not an established pattern of competing at that level.
