THE B7 - FIA CARBON FIBRE CAR SEAT

At 3.8 kg the B7 is the world’s lightest seat homologated to FIA standard 8855-1999. This is arguably the best performance racing seat on the market due to its incredibly compact design, high strength, ultralight weight, unrivalled support and manufacturing accuracy.

Some brands use misleading phrases alongside their FIA seat. Advertising, their product is the lightest. We can confidently state “Tillett are the only brand in the world that offer a FIA homologated 8855 - 1999 seat, usable in competition at 3.8kg”. This is achieved by manufacturing with our highly developed in house moulding technique. Tillett constantly invests in high levels of research and development. This creates parts with superior strength, accuracy and performance.

As with all Tillett seats, the B7 has a carefully contoured shape that supports the whole upper torso, leaving the shoulders free to steer the car unhindered. A high level of support throughout the seat and the removal of all pressure points is so comfortable, that the seat needs no covering at all. This not only helps with practicality on open top cars but also allows a much lower driving position than a seat with a thick foam cushion.

With its ultra-rigid design, the B7 retains the occupant in the intended position within the cockpit. Vital for stopping the harness and Hans device from becoming loose during an accident.

There are different edge cuts available. The B7-44 / B7-47 XL FIA are the variants we call “Edges on” meaning the seat has a continuous rolled edge. This feature allows for a more aesthetically pleasing line, making it easier to slide in and out of the car. Therefore, if you have the space, we recommend using these models.

The B7-40 FIA we call “Edges off”, these seats have the rolled edges by the leg cut away to fit them between the gearbox tunnel and the door sill of any restricted width cockpit.

We can also offer the B7-43XL “edges off” but this model has not been homologated, if a wide but narrow edge cut seat is required, we suggest selecting the very similar B6-43 XL Screamer, as this model has been FIA tested and the same shape but only 2.2kg heavier. The B7-43 XL option is special-order.
