TO BE SURE EVERYONE UNDERSTANDS THE MINIMUM AGES:
Minimum ages for car racing:
+14: Ginetta Junior, Ford Fiesta Cup, F4 Mexico, F4 Denmark, USF4? {FIA does not sanction competitions that allow under 15 year olds, thus F4 Mexico & Denmark don't get FIA Super Licence Points}
+15: F4 Italy, F4 Middle East, F4 Spain, F4 France, F4 UK, F4 CEZ, F4 US, GB4, F4 Japan, F4 Brazil, F4 Saudi Arabia, F4 India, USF2000, USF2000 Pro
+16: FIA F3, Formula Regional, GB3, Eurocup-3, Formula Euro Open, Indy NXT (might be 17), Formula Ford UK
+17: FIA F2, Super Formula
+18: FIA F1 (also for free practice, you need 25 Super Licence Points for a Friday free practice session, 40 to race in F1)
PS: I have no idea on the minimum age for national & international Sports Cars and Touring Cars except I know that in the UK it's 14 for Ford Fiesta Cup and Ginetta Juniors
