Friday’s Round 13 of the Pirelli World Challenge GTS class was postponed at Mid-Ohio Sports Car Course due to heavy rain and track flooding. Saturday’s GTS scheduled race will be held at 10:45 a.m. EDT and lined up from Friday’s qualifying lineup. The 50-minute GTS race will be a standing start. The originally-scheduled Friday GTS feature will now be added to the PWC season finale weekend at Mazda Raceway Laguna Seca. In addition, the Friday afternoon GT/GTA/GT Cup practice session at Mid-Ohio was cancelled due to the severe storms in the Mansfield, Ohio area. GT/GTA/GT Cup qualifying remains set for noon Saturday.
