Introduced to karting by the top teams around 2010, over the years laser gauges have helped many kart drivers, both professionals and non-professionals, to perfect all the tuning operations of the front geometry of the kart, mostly at the front end. This area is particularly delicate because it has the characteristic angles of the chassis (camber, caster, kingpin ...) that directly and absolutely affect the behaviour of the vehicle while driving. Therefore, having these measures under control allows you to have a kart in good condition and to obtain precise set-ups. The laser kit can therefore prove to be a useful tool to adjust the chassis but also to check its condition after intensive use or to check its state of "health" before buying a used vehicle. If you are not yet familiar with laser pointer measurement kits or are thinking of buying them and want to know more about their use, we will be explaining everything about these tools in this article: what they are, what they are for and all the ways to use them like real " professionals”.
