To do this you must have some differential affect, and that is where caster again comes into play. It will have as much forward grip as possible without binding the kart. A “free” handling kart will release/accelerate out of the corner as quickly as possible. The most challenging decision is deciding whether increasing or decreasing caster will “free up” your kart. Tracks with wide sweeping corners- less caster Wet conditions- more caster or max caster High HP classes- more caster (TAG, shifter, etc.) Low HP classes - less caster (typically sportsman and 4cycle) That said, I will try to shed some light on situations that dictate varying degrees of caster. Unfortunately, there is rarely one concrete answer for any given situation. Many generalizations are made in karting. If you deviate too far from this setting and are struggling, it is recommended that you start over at the factory settings. It is best to start at the factory recommended setting and adjust from there. How much caster should you run and when should you adjust it? That is a key question when setting up a chassis. Without caster the kart would constantly understeer, be inherently slow, and burn off the front tires in the process. Again, this change in wheel height is to achieve wheel lift at the inside rear tire and allow the kart to turn without understeering (pushing). The inside front wheel pushes into the track, while the outside front wheel travels in an upward arc away from the pavement. Think of the kart as an “X.” The RF and LR are tied together, as are the LF and RR. As caster angle increases, you mechanically move more weight given the same degree of steering input. Caster causes weight to move diagonally as you turn the wheel. Now onto how it affects the handling of the kart… The first thing you will notice when a kart has a considerable amount of caster is the increased amount of strength it takes to turn the steering wheel. On the contrary, cars do not use nearly as much caster as karts (just a few degrees) because of the rear tires are independent and can turn at different rates This number can range anywhere from 8 ° to over 20 °. Caster can be measured by the angle the kingpin bolt leans back toward the driver. Caster is the main contributor to this process, although scrub radius, spindle kingpin inclination, and frame design also play an integral role. The solid rear axle design in karts makes it necessary for the inside tire to “unload,” or lift when cornering to enable the kart to turn. Let’s first take a look at why caster is necessary and why it is so critical in karts. Cast or, on the other hand, is a lubricant commonly used in 2 cycle fuel mix. Heck, it’s hard enough to just remember how to spell cast er when referring to front-end geometry. The topics of caster and camber are quite difficult to grasp for many in karting.
