I've had an S2 Exige and I test drove an S3 S 350 Exige. At 6'-2" I could not fit comfortably in an S2. I ask Bell & Colvill about the fit when I test drove the S3 and that I was surprized how much room there is inside. He told me what I just posted in post 4 above. Lotus must have recieved lots of complaints about the fit and must have done something about it. The seat rails are different P/N.
It sounds almost too good to be true, that there is a lower adjustable seat rail. You sat in an S3 Exige V6? Did the tub grow on that? The car is about 9" longer if I'm not mistaken, but I do not know what all changed. I am trying to find a part number for these new lower seat rails, and see two part numbers. Anyone know what the differences are?
@arsenal I saw a thread on another forum about fixing the play with these long wavy metal pins that you grease and slide into the runners. I think they are in the diagram Krule links to above. Number 12 in the diagram.
I still don't see where these OEM lower runners are. I would definitely try to order them if they exist.
