T5 VTI KART SEAT– SOFT RIGIDITY OPTION The T5 kart seat is a World Championship winning product, used by Lando Norris. The T5 shape is nowadays predominantly used by younger or smaller drivers. This model has a flat bottom and a more upright back position. The 63° back angle allows a powerful shoulder turn, which helps the very young racers. With the T5 model, Tillett created the first ever “flat bottom” style seat. This innovation was eventually replicated by many other brands, as the iconic design feature gives a favourable performance advantage. KEY FEATURES The T5 range offer four rigidities. T5 VTI is the softest and most flexible T5 rigidity available. See image rigidity chart for a better understanding. The T5 model has a flat base and a 63° upright seating position for additional power in the shoulders.
