Fast Adjusters

Fast Adjusters are a go kart seat adjustment system that allows you to find the fastest seat position for any kart, driver, and track combination.

The driver is half the weight of the vehicle so if their weight is out of position the kart will be unbalanced, difficult to drive and slow. Many kart manufacturers will supply a set of dimensions for the average seat position but that will not be specific to every driver. This system gives you the ability to adjust the seat position efficiently and accurately.
