Seats

The seat is the primary sensory interface between the driver and the car. Its objective is to distribute support and feedback evenly over as wide a contact area as possible. The best way to achieve this is with a hard surface, moulded to the drivers shape.

I'm expecting to save more than 5Kg in weight with the seating, by using carbon-fibre seats that are directly floor mounted. I'm also seriously considering just a single seat that is centrally mounted. If I do go down this route, the car will still have the option to work as a two seater (side by side).

The choice of seat has a huge impact on the way a car feels and involves the driver.

Tillet W2 seat Having lived with a Tillet W1 seat for over four years in my Fisher Fury R1, my view is that a solid shell seat with no or minimal padding is the best option. Contrary to what many people think, these are by far the most comfortable and supportive seats, if they are properly shaped to the driver. Despite being a hard surface to sit on, your weight should be evenly distributed and thus comfortable over long journeys. Being a hard surface, you get full and undiluted feedback through the seat. The Tillet W1 is a half-height seat and this was a compromise to save money.

Tillet B2 seat The B2 - Ultra Lightweight Race Car Seat is the sort of thing I have in mind for this new car. Both the driver and passenger seat need to accommodate a full 6-point harness. These seats weighs just 3Kg uncovered and just 4Kg with suede insert panels.

The driver's seat in my Fisher Fury R1 is actually on runners and these added a little weight to the overall installation. Because of the tapering cockpit, the seats can only move about 3" in total. Despite being tiny, the Fury wastes a huge amount of interior space by having a large transmission tunnel and the deep side sills (to accommodate an exhaust on the passenger side). The bodywork also wraps in at the top to take up a lot of space. With this design, a lot more space will be available and the cockpit will feel much more spacious. This means a wider choice of seats and more room for them to move.

I'm not planning to have seat runners though because of the additional weight. Instead, I plan to have multiple mounting points so that the seats can be fixed in a number of positions. This will be achieved by having 'runners' moulded into the floor. This will also strengthen the floor and increase rigidity.

Harnesses

Schroth Profi II harness buckle The Schroth Profi II 6-point harnesses in my Fisher Fury R1 are perfect and with the additional space in this car, will work even better.

Mounting Points

My had the optional 6-point harness mounts welded into the chassis but, the location of these is far from perfect. In particular, the mounts for the front harnesses take an awkward route. My plan is to improve upon this significantly. This will also allow shorter (and thus lighter) harnesses.
