September 10, 2025

• TATIANA CALDERON has been replaced by Mason Filippi at Gradient Racing for the final two IMSA WeatherTech SportsCar Championship rounds at Indianapolis and Petit Le Mans, ending her stint in the team’s Michelin Endurance Cup program.
• Team owner Andris Laivins thanked CALDERON for being “a great part of the Gradient family” and promised to look for future racing opportunities together, suggesting this change wasn’t performance-related but rather a strategic move for the season finale.
• Filippi will make his GTD class debut in Gradient’s No. 66 Ford Mustang GT3 alongside Joey Hand and Till Bechtolsheimer, having impressed the team during recent testing and earned this promotion from his successful Michelin Pilot Challenge campaign.
