Six NASCAR Xfinity teams penalized for body panel modifications
While the NASCAR Sprint Cup Series was off, the Xfinity and Truck teams took to Iowa Speedway for a standalone weekend.
NASCAR released their weekly penalty report today, as well as a change in the rule book for Xfinity and Truck teams.
First off, six Xfinity teams were all hit with P2 level penalties due to the right side body panel being modified after race inspection.
