Once you're settled in and you are confident in your knowledge and skills, it is finally time to race! If you want to be competitive, you need to practice at least twice a week, which as you can probably imagine comes with added costs like, changing tires at least once a month, more things to fix, more fuel, oil, engine oil and general replacements of parts like brakes when they wear out naturally. Then to actually get into a race you will likely need to follow some steps before competing, as you do in every sport depending on your country. Then you need to ask around or look out for any social media your track might have and find upcoming races to sign up for.
Much like finding a coach, you need someone with experience and someone that can frequently come to your track. Once again mechanics aren't cheap but they are vital for fixing the multitude of things that will go wrong and break in your kart. Just like your coach, once you gain experience you won't really need a mechanic but it is very helpful to have help with the mechanical side of your kart. Things WILL break and the cost rises even more with the spare parts you'll constantly need to order. These costs are something you'll need to be prepared for because many people get into karting not knowing the cost and end up giving up because they can't keep up.
