Tillett Kart Seat - T11STD - RIGID

The T11STD ("STD" - Standard rigidity) is the most rigid seat in the T11 range. The Standard Rigidity was the standard stiffness for many years but has beome the most rigid seat in the Tillett range. Although the flexible options are more popular some require "Standard Rigidity" to balance their chassis. The more rigid "Standard" seats are also still used in 4-stroke classes where the engine provides ample torque and kart types where rigidity is not a factor.

The Tillett "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. The T11 seat model range has a flat base and a 58°/mid-angle reclined back. The design was created to position the driver lower in the kart whilst allowing a more powerful upright shoulder turn, giving the driver more control. Deep sides give ultimate support and reduce the risk ribs injuries. All Tillett kart seats are made in the UK from high impact resistant, strong fibreglass, using Tillett's unique manufacturing process that guarantees perfect control of rigidity.

"STD" (Standard) is one of four rigidities in the Tillett range

CHOOSING YOUR NEW KART SEAT
There are many factors to consider when selecting a new kart seat. If you had a seat in the past - do you know the size and shape? Does it still fit? If not, where are the gaps or pressure points? Will the rigidity suit your new kart/engine combination? 

Choosing a shape
Some would have you believe that shape doesn't make much of a difference but if the seat is not the right fit for you then the seat can cause a driver to damage their body, or hold themselves in the kart by using the steering wheel, neither of which are good for ultimate performance. A significant back angle change will alter the handling, especially for larger drivers.
The Tillett T11/58° is the most popular and most copied shape. The T11 has a huge range of sizes to cater for drivers from 12 years up to a 130kg man, slim hips, atheltic torsos (or thick rib protectors), etc.

Choosing a size
A good fit of the seat is essential for the protection of the driver and the handling of the kart. If a driver is loose in a seat they will pull down to steer with the inner hand, pulling themselves out of the kart and making it bounce at the slightest provocation.

Choosing a rigidity
Tillett Racing Seats were the first to discover that seat stiffness affected lap times. Changing the seat rigidity alters the amount of weight transferred to the outside front tyre, it is also partly responsible for the amount the inside rear wheel can lift through the corners. This gives you the ability to balance a chassis that may not be perfectly adjusted for the track surface, driving style or weather conditions.
