Help with class ( restrictions)

Someone please tell me if I’m wrong. I’ve been out of racing for a while but I seem to remember on other racing games I could see what class of car I need to be in to compete in a race. Example I’m just starting my career I go into Super Street volume 1, Challenger Series, Sport coupe but it doesn’t tell me what class the car can be to race. The only way I found is to get in a car. If the car I’m in isn’t good enough I can upgrade some tires and possibly transmission, it lets me spend money then it tells me the upgrade now puts it out of class. Wouldn’t it be nice to now what class the car can be before I spend money o. Upgrade ?
