TILLETT CAR RACING SEATS
The Tillett Car seat range started life with the W1 seat, it was made for a small company that prepared Westfields after it could not find a seat narrow enough in the market place. When Caterham were looking for a new race seat they inquired to Tillett Racing Seats and after making a couple of prototypes based on the W1 the new product was released at the 1999 Motor Show. Since then the Tillett Caterham seat has been a great sucess and is used in cars like the R500 as standard.
New Tillett car based seat models are now appearing regularly to satisfy the demands of all sorts of specialised machinery.

Ideal for sports, racing or kit cars.
The uncovered B1 Carbon seat weighs only 2.75 kg and is designed with a saloon car seating angle.
The sides of the B1 allow either a full racing harness or a normal 3 point car seat belt to be used. The carefully sculptured shape of the B1 is such that padding is unnecessary making it ideal for open topped sports cars. The seat is supplied with a Dinamica ® suede covered headrest pad as standard and can also be supplied with matching back and cushion panels at extra cost. The B1 can be floor mounted to runners or side mounted using the optional aluminum brackets which allow the seat to tip and mount directly to the floor or runner system.

The beautiful lightweight B2 Carbon seat weighs only 2.75 kg when uncovered and is made from glossy carbon fibre. The seat is designed with a low seating angle which is suited to race or track day vehicles. Due to the back shape the driver is curled into a small space allowing this seat to be fitted into many vehicles that could not take a regular performance car seat. The sides of the B2 allow either a full racing 5 or 6 point harness (Recommended on an inclined seat) or a normal 3 point car seat belt to be used.
The shape of the B2 does not require padding making it ideal for open topped cars. The seat is supplied with a Dinamica ® suede covered headrest pad as standard and can also be supplied with matching back and cushion panels at extra cost. The side mounted B2 has optional aluminum brackets for mounting to runners or directly to the floor.
There is a Carbon/GRP version also available.
Dimensions and prices are available here:The B3.5 is a thin ultra lightweight car seat shell to fit in the narrowest of vehicles.
It is available in Carbon / GRP and Black / GRP versions and comes with 6 special mounting bolts and Dinamica ® suede headrest pad.
By using this light flexible shell it is possible to use the B4 shape in vehicles where the vast majority of sports/race seats would simply not fit. The belt holes in the B3.5 allow a full racing harness to be used (a 5 or 6 point harness is recommended on an inclined seat)
Due to its very thin and light construction (1.8kg for the Carbon / GRP version) this seat needs to be used in a vehicle where the seat can be supported high up on the sides and at the headrest. This can be either from the vehicle itself, if it has a roll bar and bulkhead, or from a metal support frame constructed by the customer.
The seat is supplied with a Dinamica ® suede covered headrest pad as standard and can also be supplied with matching back and cushion panels at extra cost.

The Carbon/GRP B4 seat weighs only 4 kg and has been made to allow fitment into some of the narrowest vehicles around. Although light it is still rigid due to its twin skin construction and it holds the driver in a comfortable inclined racing position. The belt holes have been optimised to enable the use of a Hans device. The belt holes in the B4 allow a full racing harness to be used (A 5 or 6 point is recommended on an inclined seat).
The seat is supplied with a Dinamica ® suede covered headrest pad as standard and can also be supplied with matching back and cushion panels at extra cost. However, covering is unnecessary making it ideal for open topped sports cars. The side mounted B4 has optional aluminum brackets for mounting to runners or directly to the floor. You have the choice to order a 40 or 42 cm front. The two specifications remain the same size internally, the 40 cm version is made to allow fitment between the gearbox tunnel and the door sill. A 40 cm front will fit a Caterham, Westfield and most other similar vehicles. With the 42 cm version the rolled edge is left on giving a more aesthetically pleasing line to the edge of the seat, therefore if you have the room go for this model.

Dimensions and prices are available here:The new rigid Carbon/GRP B5 seat weighs from 5.7 to 6.7 kg and has been designed especially to suit the Lotus Elise / Exige.
The seat angle is a regular saloon car angle. The small narrow size of the B5 means that many other vehicle applications are possible with this seat.
The B5 sits the driver very low in the car which reduces the likelihood of hitting the crash helmet on the roll cage. This benefits the taller driver who may have problems in other seats and also helps lower the centre of gravity. The side profile developed from years of manufacturing kart racing seats gives excellent support and leaves the shoulders free to help steer the car unhindered. Although the seat is small it can fit a surprisingly large range of driver sizes and the seat has been designed to be compatible with the Hans device. The B5 is also available in a black GRP version.
The seat is supplied with a Dinamica ® suede covered headrest pad as standard and can also be supplied with matching back and cushion panels at extra cost.

The side mounted B5 has four types of brackets available.
| EB1 Elise Race/track bracket EB1 Race/track bracket set which solidly fixes to the driver’s side of the Elise and allows adjustment for leg length and angle and height. |
||
| EB2 Elise Road bracket EB2 Road bracket set that fits to the original Elise adjustment runners these allow for angle and height adjustment. |
||
| EB3 Elise Fixed passenger brackets EB3 Fixed passenger brackets in either LHD or RHD. These also allow for angle adjustment. |
||
|
TB2 Aluminum brackets TB2 Aluminum brackets for mounting to Tillett runners. These are used for fitting the B5 to many different types of vehicles but this type must be used in conjunction with runners or a minimum of 25 mm box section otherwise the dome on the bottom of the seat will sit lower than the bolting plane. |
The B6 is a narrow seat suited to many kit and track day cars. Its driving angle is based on our popular Caterham R500 seat but it has some important differences. The headrest has been moved back to prevent the drivers head from being pushed forward when using a crash helmet and the shoulder belt holes have been designed to allow the use of a Hans device.
The hip holes have also been enlarged to help easier access for wider lap belts. The composite shell is made so that the outer edge can be either removed for narrow 40 cm tubs or left on to create a continuous rolled edge around the whole perimeter of the seat. The B6 is available in Carbon/GRP or Black GRP and is supplied complete with a Dinamica ® suede covered headrest pad as standard. It can also be supplied with matching back and cushion panels at extra cost. The weight of an carbon/GRP B6 is 3.75 kg.
The mounting points for the B6 are under the seat so that the TR1 Tillett Adjustment Runners can be bolted directly to the underneath (Please note that the runners must be spaced 1 cm from the underside of the seat to give clearance for the handle to operate.). Mounting of the seat is also possible straight to the floor using a piece of 25 mm box section or runner system and Nylon spacers can be supplied to tip the seat at different angles.
(Please note that the Caterham R500 seat is only available through Caterham.)
