All four HMS Cup teams were penalized Wednesday by NASCAR for modifying hood louvers (vents) on their respective cars, an issue that was discovered prior to practice last weekend at Phoenix Raceway.
Among the penalties were the suspension for four races of all four teams’ crew chiefs. While HMS is appealing the penalty, it has elected not to ask for a deferral of the suspensions and is going to begin having those affected sit out this weekend at Atlanta.
