Jon arrived this morning with his seat. The aim was to get him in the car to establish the seat position so I could continue with mounts and harness positions.
After some discussion we decided that, because Jon is a lanky fella, the best solution would be to put the seat straight on to the floor. This involved removing the original rear seat mounting rail. Once this was out Jon sat in and happily could reach the pedals fine.
Jon - Box section of the floor was cut out before seat got mounted in:
(The seat cannot go lower than this!)
FIA regs mean that there must be 40 square centimetres of contact with 3mm thick counter plates at each mounting point either side of the floor. These counter plates were made and welded in, and the seat mounted.
Seat in, feels lovely!
