On KZ karts, brakeforce distribution is the same whether the track is fast or slow

Well done!

On karts with KZ engines, all drivers, on all tracks, usually use brakeforce distribution shifted towards the front end. However, the settings change when you race on a fast track, such as the Circuito internazionale Napoli in Sarno, compared to a slow one, such as La Conca. In the first case, I prefer the brakeforce to be shifted more towards the front end compared to the setting for a mixed track with shorter straights. Speaking in percentages, I would say that on a circuit with long straights, brakeforce is shifted towards the front end by about and extra 10%. Clearly, however, it’s up to the driver, who knows the braking system of their kart, to set the correct values.

INCORRECT!

That is not the case, because the volume of water in the cylinder is not directly linked to the ability to dissipate heat. Knowing that this operation depends on the temperature difference between the walls and the water itself, we need to know which areas need to stay cooler and which ones “wish” to stay hotter, and we need to adjust the flow velocity according to what we want to achieve. In this sense, a smaller water chamber makes it possible to predict and influence the flow of water more than can be done in a larger chamber.

Compared to aluminium ones, resin floor trays not only weigh more, they also allow you to vary the set-up of the kart. Depending on the weave of the various fibres, a resin floor panel changes the flexion in the longitudinal or transversal direction. Moreover, the different thickness allows the chassis to have a different level of resistance to torsion.
Last, but not least, a resin floor tray remains unchanged even when the kart comes into contact with a kerb.
