🇺🇸 Colin Garrett

Colin Garrett is an entry-level professional racing driver competing in GT4 endurance racing and road-course touring cars. He races GT4 cars in the shared-driver format for Auto Technic Racing in GT4 America and competes in single-driver sprint racing for Rooster Hall Racing and NineFour Motorsports. Garrett holds an FIA Silver grading, which sits below the full-professional Gold and Platinum grades in sportscar racing and typically indicates a driver developing toward that level.[1]

Garrett won the 2023 TC America championship with Rooster Hall Racing, taking seven wins from 15 starts in that sprint series. In GT4 America, where he has raced since 2023 in the multiclass endurance format, he has taken three wins and ten podiums across 28 starts, including shared-car victories with co-drivers in the Pro-Am and Silver classes. His first indexed racing came in 2019 with oval-track NASCAR machinery; he has since moved to road racing and road-course competition, with recent additions in 2026 to his record showing three wins and five podiums from nine Zenith Racing Series starts, where he currently sits fifth in the championship standings with rounds still to come.[2]

Garrett races regularly against established touring-car and endurance professionals. He is closely matched with Tyler Gonzalez, a Silver-graded driver and 2023 TGRNA GR Cup North America Am champion with substantial experience in IMSA Pilot Challenge and GT4 America, but usually finishes behind Kenton Koch, a Gold-graded professional who won the 2025 GT World Challenge America Pro and 2025 GT4 America Silver championships and has raced extensively in IMSA competition. Garrett has finished ahead of Ty Gibbs, the 2020 and 2021 ARCA Menards Series champion, and Austin Cindric, who won back-to-back NASCAR Xfinity titles in 2020 and 2021, though both men compete primarily in single-seater and stock-car formulae where Garrett has limited experience.
