The brackets that support the seat, attaching it to the bearing cassettes, are important elements in the set-up and behaviour of a kart: their positioning (as well as shape, length, diameter, thickness, etc.) changes the stiffness of the chassis and, consequently, the vehicle’s behaviour. There is no law that establishes the correct positioning of the brackets and nothing there is nothing against criss-crossing them. Of course, it is a compromise that requires bending the brackets themselves, but it can be done. The result is a cross between the stiffness obtained by fitting a single support bracket and that of fitting two of them. Nevertheless, it is still greater than two brackets fitted horizontally (i.e. at less than a 45° angle). Maximum stiffness, and consequently maximum grip, is obtained by fitting two "vertical" brackets (at an angle greater than 45°).
