TILLETT CAR RACING SEATS

Tillett Racing Seats - Car Seat Gallery

Don't judge a seat by it's cover

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.

The B2 Ultra Lightweight Race Car Seat

B2 Shown with optional Dinamica ®

The B2 Ultra Lightweight Race Car Seat

The beautiful ultra-lightweight B2 seat weighs only 3 kg and is made from glossy carbon fibre. The seat is designed for a low reclined driving position, which is suited to race or track day vehicles. Due to the curved 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 B2 is suitable for a 5 or 6 point full racing harness (4 point is not recommended on a reclined seat). Like all Tillett seats, the ergonomic shape of the B2 is so amazingly comfortable it does not require padding, making it ideal for open topped cars. The seat is supplied as standard with a Dinamica® suede covered headrest pad and has an option of matching back and cushion panels at extra cost. The weight of the seat with covered panels is 4 kg. 8° bracket options include the TB1 which point inwards under the seat and keep a small footprint. These allow adjustment of the seat angle and mount directly either to a flat floor, or the STRi or PTRi runner system. TB4 brackets which are 30 mm taller are also available.

TB1O8 brackets are the same as the TB1 but point outwards. There is also a beautiful fully machined billet aluminium TBFIAO8 bracket set which also point outwards. If leg length adjustment is required on outward pointing brackets the wider STRO runners can be used.

The B3.5 Race Car Seat

B3.5 Carbon/GRP shown

The B3.5 Race Car Seat

The B3.5 is a thin, ultra-lightweight single skin seat shell, which is designed to fit the narrowest of specialised track vehicles. The B3.5 seat is derived from the inner moulding of the B4 and has the same reclined driving position. Available in either carbon/GRP or black GRP and comes as standard with a Dinamica® suede headrest pad. By using these light flexible shells, it is possible to use the B4 shape in vehicles where other sports/race seats would not fit. The belt holes in the B3.5 allow a full racing harness to be used (A five or six point harness is recommended). Please note, these seats are not self supporting. Due to their very thin and light 2.1 kg construction, they need to be used in vehicles where the shell can be fixed high up on the sides, the headrest and the area under the legs. This can be either from hard points on the vehicle itself, a roll bar, bulkhead, or from a specially made support frame constructed by the customer. The Tillett bracket range will not fit single skin models.

Dinamica® suede back and cushion panels are available at extra cost.

The B4 Race Car Seat

Carbon/GRP shown with optional
aluminum brackets

The B4 Race Car Seat

This super comfortable reclined shape gives the ideal angle for a sports prototype racer, or to replicate a formula car on a simulator. The B4 weighs 4.9 kg and has been made to fit many narrow vehicles. Although light, the seat is still rigid due to its twin skin construction and the shape lowers the driver significantly. The belt holes in the B4 allow a full racing harness to be used (5 or 6 point harnesses are recommended on reclined seats). The shoulder holes have been optimised to enable the use of a Hans device. The B4 comes complete with a Dinamica® suede covered headrest. Matching padded cushion and back panels are available at extra cost. However, the B4 shape is so comfortable covering is unnecessary, making it ideal for open topped sports cars. The B4 has six M8 mounting points; two are up high at chest level and these upper mountings give more mounting options in race cars without a solid floor.

The four lower fixings are for 8° bracket options such as the TB1, which point inwards under the seat and this creates a small footprint. They allow adjustment of the seat angle and mount directly either to a flat floor or the narrow STRi, PTRi runner systems. Brackets that point outwards from the seat include the TB1O8 brackets and a beautiful fully machined billet aluminium bracket set called the TBFIAO8. If leg length adjustment is required on outward pointing brackets the wider STRO or PTRO runners can be used.

With the B4 you have the choice to order a 40 or 43cm front. The two specifications remain the same size internally. The B4-40 is cut back on the edges to allow fitment between the gearbox tunnel and the door sill of a narrow cockpit. A 40 cm front will fit a Caterham, Westfield, and most other similar vehicles. With the B4-43 the rolled edge is left on, giving a more aesthetically pleasing line to the edge of the seat and this is easier to slide over if access is restricted.

Available in Carbon/GRP or black GRP.

The B5 Race Car Seat

The B5 shown is the carbon/GRP version

with suede covering

B5 Carbon GRP and B5 GRP

Although the B5 is used in many different vehicles, the seat was originally designed to complement the narrow Lotus Elise/Exige platform cars. The B5 is designed with a regular saloon car angle and the side profile is developed from many years of manufacturing kart seats. This experience in holding the body safely without padding gives a car seat with excellent support, whilst at the same time leaving the shoulders free to steer the car unhindered. Like all Tillett seats it has a compact exterior and a thin base, which drops the seating dome right on the floor, thus increasing the head room significantly. Although the B5 has small exterior dimensions it can fit a surprisingly large range of driver sizes and the low profile headrest and belt holes have been designed to be compatible with the Hans device. The seat is not only exceptionally light but also very rigid, which adds to the handling, feedback and feeling of security. The seat can be used with a three point road seat belt or a racing harness.

The uncovered GRP or carbon/GRP version of the seat weighs an impressively light 4.5 kg and with the Dinamica suede covered pads it weighs 5.5 kg. We recommend the Dinamica covered panel set for road use.

The B6 Race Car Seat

The B6 Carseat
Click to view full size

NEW 2022 B6 Carbon GRP and B6 GRP

The updated B6 is a narrow lightweight seat suited to many track day cars. For 2022 the rear frame shape has been improved structurally and cosmetically and now matches the FIA approved B6 Screamer. A bottom mount option and a lighter construction mean the standard B6 is not FIA approved. However, the new update increases the strength and rigidity over the previous model.

The new belt hole surrounds resist being pushed off and the flatter inner profile intrudes less into the hip area. The hole sizes are made to suit the requirements of a Hans device. The rolled outer edge along the leg support area can either be removed for a narrow 40 cm cockpit or left on to create a continuous rolled edge around the whole perimeter of the seat. The "edges on" version is designated the B6-44.

When ordered with the side mounts the seat can use all the 2° bracket sets made for the B6 Screamer. With the "bottom mount" model, the STRi and PTRi Tillett adjustment runners can be bolted directly underneath using the TK5 fitting kit. By using at least 40 mm of spacers under each M8 mounting point, the B6 can be bolted directly through the floor without runners. The Tillett Nylon or ally spacers can be used for this purpose. The B6 is available with a choice of two front surface finishes, carbon/GRP and gloss black GRP. Both types come as standard with a suede padded headrest. To reduce vibration, they also have the option of Dinamica® covered suede panels. The weight of a B6 is 4.5 kg or 5.5 kg with suede covered panels.

The B6 XL Race Car Seat

The B6 Carseat
Click to view full size

B6 XL Carbon GRP and B6 GRP

The B6 is also available as a lighter construction non FIA model in the XL size, allowing a larger driver over 100 kg to sit in an ultra-narrow cockpit. The externally narrower version of this seat is called the B6-43 XL, which has the edges specially cut to reduce the outer width. With the 47 XL model the outer edge is left on, creating a continuous rolled edge around the whole perimeter of the seat. There are two mounting point options. The captive M8 fittings are either on the underside of the seat "Bottom Mounts", or "Side Mounts". With side mounting points the seat can use the same 2° bracket types as the FIA B6 XL Screamer. With bottom mountings, the STRi and PTRi Tillett adjustment runners can be attached underneath the seat using the TK5 fitting kit. By using at least 40 mm of spacers or box section metal under each M8 mounting point, the base mounted B6 XL can be bolted directly to a flat floor solidly without runners. The Tillett Nylon or ally spacers can be used for this purpose. Please specify either bottom or side mounts when ordering.

The B6 XL is available in a Carbon/GRP or gloss black GRP finish on the front surface and comes complete with a suede covered headrest pad as standard. To give that extra bit of comfort, the B6 XL has the option of Dinamica® covered suede padded panels. The weight of a B6 XL is from 4.7 kg or 5.7 kg with suede covered panels.

The B6 Screamer Race Car Seat

Click to view full size

NEW updated B6 Screamer Carbon GRP and B6 Screamer GRP

The B6 Screamer is FIA approved to 8855-1999. The seat is one of the most compact FIA race seats available and can be used comfortably without any padding, giving ultimate feel and feedback, which is essential in a competition seat. The ability of this seat to be used without covering and the carefully sculptured shape mean that you can achieve a lower driving position than most of the competition. Its perfect ergonomic shape gives excellent support, whilst at the same time leaving the shoulders free to help steer the car unhindered. The Screamer is manufactured using our internally developed moulding system, which creates superior strength and accuracy. The seat is also ultra rigid, which keeps the occupant in the intended position within the cockpit. Vital for stopping the harness and Hans device from becoming loose during an accident. Another benefit is that the uncovered version is more convenient to use in harsh environments.

The seats are supplied as standard with a Dinamica® suede covered headrest pad. As an extra cost option additional padded Dinamica® cushion and back panels are also available. The weight of the B6 Screamer is light at 6.1 kg, or 7.1 kg including the suede covered cushion and back panels. With the B6 Screamer you have the choice to order a 40 or 44 cm front and both types are the same size internally. The B6-40 Screamer version is made to allow fitment between the gearbox tunnel and the door sill of a restricted width cockpit. With the B6-44 Screamer the continuous rolled edge of the composite is uncut, giving a more aesthetically pleasing line to the edge of the seat and making it easier to slide in and out of the car. Therefore, if you have the space, we recommend using this model.

Both cut and uncut models are FIA homologated to 8855-1999.

The B6 XL Screamer Racing Car Seat

Click to view full size

NEW updated B6 XL Screamer Carbon GRP and B6 XL Screamer GRP

The B6-47 XL Screamer is 30 mm wider than the regular B6 Screamer. Just as in the standard size there is also a cut edge version called the B6-43 XL Screamer. The narrower 43 XL is made to allow fitment between a gearbox tunnel and door sill in a restricted width cockpit. The XL size enables a driver weighing over 100 kg to use the seat. The 43 XL version will fit easily in the Elise/Exige using the EBS or EBR+ERAIL bracket sets.

On the B6-47 XL Screamer the rolled edge is left on, making it easier to slide in and out of the car and giving a more aesthetically pleasing line to the edge of the seat. The size of the two versions remains the same internally. The weight of the B6 XL Screamer is 6.1 kg, or 7.1 kg when including the suede covered panels.

Both models have four M8 side mounting points as standard, which allow adjustment of height and angle when using our 2° competition brackets. These brackets fit the seats rigidly down to a flat floor giving the lowest possible driving position. The B6 Screamer seats are incredibly comfortable during long journeys, or endurance races without a cover, making them ideal for open topped cars.

Both cut and uncut models are FIA homologated to 8855-1999.

The B7 Race Car Seat

NEW 2021 updated B7

The lightest FIA seat in the world

The 2021 homologation of the B7 further improves the quality and performance of this super strong yet incredibly lightweight carbon race seat. The B7-40-21 has the narrowest dimensions of any FIA 8855-1999 homologated seat and at 3.8 kg it remains the lightest FIA seat available anywhere in the world. The standard width B7 is available in two versions; The B7-40-21 has a maximum width of 40 cm, and the B7-44-21 has a maximum width of 44 cm. The two models are the same size internally and are both separately FIA homologated to 8855-1999. The 44 cm version is made for cars where there is the width for the rolled edge to remain around the leg area, this smoother edge helps ease access to and from the car. Both models are ultra rigid, which keeps the occupant in the intended position within the cockpit. Vital for stopping the harness and Hans device from becoming loose during an accident.

The B7 remains perfectly comfortable for long journeys or endurance races as a bare shell, with only the standard headrest pad in place. Other makes of FIA seats always have to add the additional weight of both foam and covering. Both models can be ordered with the extra cost Dinamica® suede panels, which add grip and reduce vibration. These additional panels add 1 kg.

The B7-XL-21 is improved for 2022 and is FIA homologated to 8855 -1999. The XL version of the B7 XL is 30 mm wider than the standard width B7 but only 20mm wider across the mounting points.

B8 Racing Car Seat

Click to view full size

NEW B8 Carbon GRP and B8 GRP

B8 (NEW!)

The B8 road/track race seat allows a driver to attain a low driving position, whilst sitting at an angle which suits road going production sports cars. The B8 requires minimal padding which provides great feedback from the chassis and a perfectly supported driving position. It is especially good for taller drivers wishing to lower themselves in the car without sacrificing any comfort on long journeys. The compact B8 is wider than the B5 and the cut edge B8-43 allows this larger seat to fit into sports cars with very narrow cockpits.

The two edge width options are the B8-43 and the B8-44.5. The B8 uses all the 2° brackets that are currently available for the B6 and B7 FIA race seats. This includes the Lotus Elise/Exige brackets which would need the narrow cut edges of the B8-43. The B8-44.5 is more suited to a saloon car such as a Nissan GTR or Porsche. The swept away hip area is convenient to use with a standard three point seat belt and the newly designed crotch and shoulder holes allow a full racing harness to be used. The shoulder belt holes have been made tall enough so that a Hans device can be used if required.

The B8 seat is very light at 4.7 kg. The optional Dinamica suede panel set adds 1 kg and we recommended these for daily road use.

The B9 Race Car Seat

Click to view full size

NEW B9 car seat

The B9 is a lightweight carbon fibre road or track seat with a beautiful high gloss finish. The B9 model updates the popular B1, which was first released in 2002. The B9's twin moulding construction is rigid, strong and super lightweight at 3.35 kg. New uprated side mounting points, as used on our FIA homologated seats, add to the strength and the new shape allows use of all our 2° bracket sets. This strength and adaptability make the B9 ideal for a cockpit without a bulkhead, benefiting from the additional strength. The new option of a narrow cut B9-43 will suit cars with restricted cockpit space, such as the Elise/Exige. The body contact area on the B9 is so carefully sculptured it is comfortable without padding, making the seat ideal for open topped sports cars. The millimetre perfect ergonomic shape gives ultimate feel and feedback, essential in a performance seat. The B9 has swept away sides which allows a standard road seat belt, or 6 point racing harness to be used and the shoulder belt holes are tall enough to accommodate a Hans device. The seat comes with a Dinamica® suede covered headrest pad as standard and has the option of matching back and cushion panels, with special foam in the base to reduce vibration and shock. The cushion and back seat panels are recommended when the car is mainly intended for road use.

The W1i Race Car Seat Carbon/GRP

W1i Uncovered carbon/GRP shown with
optional back frame

 

W1i Carbon GRP and W1i GRP

The low back W1i Tillett car seat is internally the same shape as the standard B6 but without the headrest. The seat can accommodate a driver up to approximately 100 kg with a 36 inch jeans waist size. There is a choice of a carbon or black GRP front finish and two specifications of edge cut at the leg support area. The W1i-40 version is trimmed back to allow fitment between the gearbox tunnel and the door sill of narrow vehicles, such as a Lotus 7 replica. The W1i-44 has the rolled edge left on to give a more aesthetically pleasing look to the edge of the seat. The W1i is also available with a floor mountable backframe option. This second composite moulding is bonded to the front skin, making the W1i a fully self-supporting rigid structure. Its four M8 embedded fittings allow it to mount directly to the floor, or onto the Tillett STRi or PTRi seat adjustment runners using the TK5 fitting kit.

With the side mounting option, it is possible to use the 2° race brackets as used by the FIA B6 and B7 seats. The weight of a W1i with the backframe is 3.5 kg and 1.9 kg without. Low back W models are most suitable when a headrest is not practical, maybe for an application where there is already a headrest support in existence. The W1i shape is often suited to Formula Student university projects.

The PTBi brackets are made from high grade anodised black aluminium and are 6 mm thick with a beautifully machined edge and engraved logo. The brackets allow the seat to be tipped, raised and lowered using the various hole and slot combinations. The optional aluminium "Pegged spacer kit" can be used to strengthen the front slots in the event of an accident.

PTBi brackets can be used with STRi and PRTi seat adjustment runners. However, we advise against using any seat adjustment runners in a race car, as they are only intended for road use. A pair weigh 1.2kg.

TILLETT CAR SEAT RANGE

The Tillett car seat range was born in the mid 90's when a small low back car seat shell was developed for a customer. A few years later Caterham's Jez Coates visited Tillett Racing Seats looking for "something like a kart seat" to replace their inadequate fibreglass race seat. Initially there was much reluctance by Caterham to commit to the highly technical composite injection moulds suggested as the new way of composite construction. Therefore, to prove the value of the design hours were spent sculpturing the seat into prototypes which proved to Caterham that it would be a great product. They loved the new seat design, and it was released in the Caterham R500 at the 1999 Motor show. This innovative race seat was the first to feature a unique twin skin construction, making the seat super light yet rigid and it created a demand for other similar Tillett branded car seats. Tillett Racing Seats continue to break new ground in the performance car seat market, making the worlds lightest and most compact FIA race seats available.

Tillett Racing Seats have now been supplying composite car seats to Caterham Cars for 22 years. Caterham were so impressed with our seat quality and design that most of Caterham's carbon components are also made at the Tillett factory in Kent.
