I have been trying for 3 days now to be able to race my A or B class muscle cars in the even rated for under 650 HP. It only allows me to select d or c cars even though I have many cars matching the specs for the race. Need help soon really want to race since everyone else is allowed their A cars.
Please use this existing thread for discussion on that topic:
