🇺🇸 Keith Grant

Keith Grant is an entry-level professional competing in national solo and multiclass sprint racing across multiple series. Bronze-graded under FIA categorisation, Grant races for his own operation, Grant Motorsports, in the Porsche Sprint Challenge North America Cayman series, where he campaigns a Porsche 718 Cayman GT4 RS Clubsport in the CAY P/A class. His primary earlier home was IMSA Prototype Challenge, where he spent five seasons with JDC MotorSports piloting LMP3 prototypes across the circuit.[1]

Grant's record spans nine seasons from 2018 to the present across six series, amassing eight wins and 26 podiums from 68 starts. His breakthrough came in 2026 with the Porsche Sprint Challenge, where he has taken two wins and nine podiums from ten starts in a multiclass field of two classes. International GT supplied five starts that year, all of them podium finishes including five wins, marking his most concentrated period of success. Trans-Am brought four podiums across nine starts between 2022 and 2025. His earlier years centred on IMSA Prototype Challenge, which yielded three podiums from 26 starts; he also competed in SCCA Majors, SCCA Regionals, SVRA and the SCCA Runoffs as a secondary focus.[2]

Grant races alongside field-leading professionals in the multiclass championships he contests. In IMSA Prototype Challenge he was closely matched against Tonis Kasemets, a Silver-graded professional and 2022 series champion with extensive IndyCar, IMSA and Indy NXT experience, and Jon Brownson, another entry-level professional with 32 starts in that series. His International GT campaign placed him in a field that included George Kurtz, an established professional and champion of the 2023 GT World Challenge America Pro-Am and 2026 IMSA WeatherTech LMP2, and he also finished ahead of Kyle Kirkwood, an elite professional and champion across Formula Regional Americas, Indy Pro 2000 and Indy NXT, across his career.
