The Tillett B3.5 is a thin ultra lightweight shell seat based around the B4 but designed to fit in the narrowest of vehicles making it ideal for sports prototypes or formula cars. By using this light flexible shell it is possible to use the seat 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 a reclined seat. The B3.5 seat is also fully compatible with FHR devices. We recommend a 30° recline device to suit the recline angle of the seat.Designed to fit into the narrowest of cockpitsReclined seating position ideal fro track cars to keep the centre of gravity lowerUltra lightweight (from just 2.1kg)Fully compatible with use with FHR / HANS devicesBody mirroring shell shape provides high levels of comfort and provides maximum chassis feedback to the driverSuitable for most driver shapes / sizes.
