Thanks for the replies, guys. I have had an idea which I think will help. When I built the tunnel I made it wide enough to accomodate the flange on the diff, which would actually be behind the seat when it is set up for my short arsed legs. I can therefore redesign the tunnel to give me an extra 40mm each side, which should make all the difference. It's a fair chunk of work but will be much better so I think that is the way to go. I then have a much wider choice of cheap seating at my disposal. Spending a grand on a pair of Exige seats simply aint goint to happen
I don't think I will spend that on the whole car.
Dave.
