If you love go-karts and you have some land to your name, then chances are that you have, at one point or another, wondered how much those serious go-kart lovers spend on their home-built go-kart tracks. You'll be happy to know that the answer is "not as much as you might expect." When it comes down to it, unless you're picky about terrain, all you really need are some digging tools and something to build the barriers with. Below are some of the basic ingredients that go into a great homemade go-kart track.
There are other things you can use in place of tires, but tires remain one of the best ways to build a safety barrier. Tires serve as effective bumpers to keep you from crashing into a tree, and since they give more of a soft bump than a fierce slam when you crash into them, there's a lot less fear of whiplash.
There are other options, though. You can fill rain barrels, for instance, or use plywood. If you want a lot of tires fast, start collecting. You can check out junkyards or even put an ad up online. Seeing as garages charge a fee to get rid of your old flats, people in your area might be glad to just dump them at your front gate. Make sure to pile extra tires around the turns, as this is where the vast majority of spills, slips, slides and crashes are going to occur.
These are what you need if you want to have a smooth surface to race on. You simply lay down a layer of concrete and cover it in tar. If you'd rather not spring for this admittedly pricey expense, or if you just want to get started racing right now, it may be cheaper to simply invest in some off-road karts. This will let you enjoy a rugged kind of race without having to spend the money it takes to pave an entire kart track.
