The T11 is the seat shape most often used by the professional teams. With young drivers growing ever taller, there was a need to lower the body weight. Tillett designed the T11 range to obtain an even lower driving position than the T5, whilst at the same time keeping an upright shoulder position, which allows a driver to retain full control of their kart without upsetting the weight distribution.
The flat area on the bottom of the seat is large and the back angle is 58 degrees.
The VG seat is the flexible version that is best for most condition of racing
