International GT is a multi-class sprint series running production-based and cup-specification Porsche cars, together with the Lamborghini Huracán Super Trofeo in its LAM class. The field is entry-level professional, with a pro-am structure; the EXH and LAM classes attract a mix of Silver and Bronze drivers alongside amateurs, while the GT4.R, Cayman, and 992 classes are predominantly Bronze. Top drivers include Memo Gidley and Dylan Murry. The series functions as a stepping stone upward from club and regional racing; most arrivals come from NASA, PCA Club Racing, and American Endurance Racing, and drivers move on most often to GT4 America and GT World Challenge America.
