The NTT IndyCar Series has added a special practice session for this weekend’s Xpel 375 at Texas Motor Speedway.

The intention of the extra 30 minute session is to rubber in the second groove of the 1.45 mile oval. The section of the course has proved problematic the last two years due to the stain of PJ1 used during the NASCAR events.

Seven drivers will participate – Ed Carpenter, Helio Castroneves, Pato O’Ward, Graham Rahal, Felix Rosenqvist and Takuma Sato.

The session will start at 4:00 pm Saturday, while final practice for all cars will start at 4:45.
