The T11 kart seat is a World Championship winning product. The T11 shape is the most popular for adult sized karts, typically used by manufacturers and professional kart racing teams. This model has a flat base and a mid-angle reclined back. This design was created to position the driver lower in the kart whilst allowing a more powerful upright shoulder turn, giving the driver more control. For drivers with a long torso, the T9.5 is further reclined. KEY FEATURES The T11 range offer four rigidities. T11VTI is the softest rigidity we offer in the T11 range. See image rigidity chart below for a better understanding. The T11 model has a flat base and a 58° reclined back for a lower seating position. T11VTI is the softest T11 rigidity on offer and produces maximum rear wheel lift from stiffer seat models.
