This one is "the best advice " , belonging to a club is always the best place to start and the best way to find free advice from people with the same passion, otherwise you might end up (like lot of beginners )with a total disgust of this hobby after your encounter you first problems like I have seen it happen many times over the years.
Plus once your lads will start to drive and take pleasure in it, they will then be able to measure themselves against other racers and progress that way.
