Ribtec Rib Protectors have helped many World FA Champions to success.

Carbon Floor Trays

Aluminium floor trays weigh 1100 gm on average, by comparison a Tillett Composite floor tray can weigh as little as 330 gm.

Carbon Race Seats

Many kart seats in the market place are sold as containing carbon, but these are almost always glass fibre with one cosmetic top layer of carbon fibre, Tillett seats are never made to fool the customer in
any way.

TILLETT T5 & T11 KART RACING SEATS

 

T11

The T11 is the seat used by Davide Fore to win the 2004 World Championship and is the most popular hand made seat.

This shape was developed because young drivers are getting taller. The high centre of gravity can cause handling problems when the tracks are grippy and covered in rubber. The T11 shape has now become one of the most imitated throughout the world.

The T11 creates a very low head position, giving a low centre of gravity and better aerodynamics which helps the taller drivers. The shape and size is the same as the T5 Reverse only with a more inclined seating angle.

T11t

The new T11t is our popular T11 made with a material specification designed to match the needs of the current 2009 Tonykart chassis. The T11t seat gives an extra dimension of performance over the standard seat. Priced the same as a T5 Rev or T11 Standard.

There are 8 T11 sizes available; XS, S, Harvey, Man, MS, ML, L and XL. (Prices are identical to the T5 Reverse)

New Harvey size available for drivers falling between the S and Manetti size.

Equivalent size T11 seats will be slightly larger than the T8, T10 shapes. For example; the size of a ML T11 falls in between the ML and L sizes in T8 and T10.

T5 Description

T5
The fully covered T5 is developed from the Original 'Tillett' seat. It fits correctly in every size and the fixed cover with integral padding makes the seat super comfortable and stops the driver from sliding around during cornering.

The T5 has a flat bottom, which helps drivers get a lower centre of gravity, ideal for those using high grip tyres .

T5 Reverse
As used to great success by Wade Cunningham to win the 2003 World Championships at Sarno.

Unlike the fully covered T5, the T5 Reverse has a smooth inside, this allows uncovered 1/4 and 1/2 covered seats to be produced in the popular T5 shape. The Xscd T5 Rev is popular with the 10 to 11 year old Cadet/Mini kart drivers. Now there is also a new C size available for tall thin Cadets.

Because it was made off the back of the T5 moulds, equivalent size T5 Reverse seats will be slightly larger than the standard T5 moulding. For example; the size of a ML T5 Reverse falls in between the ML and L sizes in other shapes.

Drivers with wide hips often prefer the T5 Reverse shape.

 

Please note that the T4 shape is no longer avalable online but can be ordered by contacting Tillett Racing Seats direct.

CHOOSING YOUR SEAT

When choosing your new Tillett seat, please take into consideration that it is often tempting to pick a seat that is too big.

In a new seat, it is wise to choose a tight fit, as this offers the best protection for the ribs and the body. When a seat is too loose, the chances of damaging the body are much higher. In the course of an accident, if you move towards the side of a seat, the impact is much greater than if your body is hard against the side of the seat. In the same way people wearing no seat belt in a car crash will damage themselves far more than one instantly restrained by a seat belt. The best way to work out your seat size is by using your waist size and weight.

Rigity and Weight

RIGIDITY
Altering the rigidity of the seat will affect the handling of the kart. To make sure that the seat you buy this year will be the same as the one you buy next year, Tillett Racing Seats are made to set specifications. Other seat manufacturer's products often vary in thickness and the mouldings are nearly always resin rich, which makes them inconsistent in rigidity and strength. Our seats are unique in that they can be purchased with various consistent levels of rigidity.

THE T5, T7, T8 Handmade, T9, T10 and T11
When you buy most Tillett seats, you can choose between at three levels of rigidity.

Flexible (a seat that allows the chassis to flex more)
Standard (based on most karts uncovered seats)
Rigid (a stiff seat with little flex )

THE T8 & T12
The T8 and T12 seats are injected into predetermined cavity, and by changing the materials, we can alter the performance characteristics with total consistency. Therefore you can order soft or standard throughout all the T8 and T12 range. (For an increased range of rigidity order the hand made T8 and T11 versions can give you the same shape with an increased range of rigidity.)

THE FLEXIBLE
T5VG, T7VG, T8VG, T9VG, T10VG & T11VG
The flexible seats were originally designed for use with Formula A karts running on high grip tyres. Nowadays we also find that these seat work particularly well with engines like the Rotax Max. An engine with low bottom end power often needs more chassis flex to lift the inside rear wheel and this helps to avoid bogging the engines down when driving out of the corners. However, many people use the flexible (VG) seat in all sorts of different classes, often improving lap times. The above is not a cast iron rule and does depend on track condition, make of chassis and tyres. A chassis, which has a problem and is not balanced, or is bogging down out of corners, can sometimes be transformed by changing the seat's rigidity.
There is also a VP rigidity, which is very thin and flexible and is only ordered by customers determined to get the most flexible seat possible. These have to be made to order, and can not be ordered online.

WEIGHT
It is easy to make a seat light, it is not so easy to make a lightweight seat that can hold a driver securely without breakage during an accident. Using carbon-KEVLAR® fabric is almost irrelevant if the resin and curing processes do not compliment the expensive fibres, with an ultra light seat most of the seat strength can be lost and fracturing can occur if every element of the seats construction is not correct.

The Carbon/Kevlar seats can be as stiff or as soft as all our other types.

The rigidity that matches our standard T5, T7, T8, T9, T10, T11 and T12 seats and most other makes, is designated 'K' in the table below.
The rigidity to match a flexible T5VG, T7VG, T8VG, T9VG, T10KG and T11VG is designated the "KG".

For a lightweight, rigid seat, order "CR".
