The T11 is the most popular adult shape and the one most often used by professional karting teams and manufacturers. With every generation growing taller, a new seat was needed. A large flat area on the base was created and combined with a more reclined back angle of 58°, lowering the head height significantly. Whilst lowering the body weight gives a performance advantage, it is important to maintain an upright shoulder position to allow enough power to be transferred to the steering. The driver is likely to "pull to steer” if they are too reclined, which is bad for handling and body stability. The T11 shape enables the correct upper torso angle to retain firm control and therefore performance.

The T11 is manufactured using our own highly developed moulding technique, which makes a seat with a consistent laminate weight and thickness. It also has smooth surfaces front and back, which keeps the seat looking professional and clean. Unlike previous mechanised production methods, this unique system gives us the opportunity to tune the rigidity. The T11 model also benefits from a specially developed high strength resin and it contains a much higher fibre to resin ratio than regular laminates. This makes the seat less likely to splinter during drilling and more able to withstand impacts.
