The Tillett B3.5 seat is designed and manufactured in the UK from a choice of either GRP or Carbon/GRP composite. The shape of the seat has been designed for optimum support with high levels of comfort even when used without padding. Because the seat is designed for a close fit the driver feels more connected to the chassis with increased feedback. The belt holes allow a full racing harness to be used (a 5 or 6 point harness is recommended on a reclined seat) and the shoulder holes have been optimised to enable the use of an FHR / HANS device.

The B4 has six M8 mounting points: 4 to accept a pair of side mounts and an additional two are at chest level to give more mounting options. The four lower fixings are for the aluminium TB1 mounting brackets (sold separately) and with these the B4 can be mounted directly to the floor or on top of runners. The B4 is available in 2 widths, 40cm or 43cm. Both options have identical internal dimensions but the 40cm option has the external rolled edge removed to allow fitment into smaller cockpits.

Supplied with a Dinamica trimmed headrest. A 2 piece Dinamica trimmed pad set is available to purchase separately if required. Side mounts not included. To view compatible mounts click HERE.
