For the Grand-Am series, Ferrari developed a modified version of the 458 GT3 in 2012. It weighs the same but produces less downforce; the more heavily restricted engine produces 507 PS and revs to 8000/min. Instead of a dual-clutch, it features a conventional sequential transmission, without traction control or ABS. It debuted at the 2012 24 Hours of Daytona, and AimAutosport.com became the first team to take a win with it. On September 9, 2012, Jeff Segal and Emil Assentato clinched the Grand-Am Rolex GT Championship with a second-place finish at Laguna Seca.
