Getting back on topic I'm impressed with the flexibility the rails on the driver's seat give the car, although there will be a significant amount of adjusting the straps between drivers!
I'm 6' and the position I found felt really good.
Dave's, errr, shorter and with the booster cushion he seemed to be sorted, although we did have this conversation last night:
'I'll probably still lean forward'
'No Dave, I assure you, with the harnesses tightened down you will NOT be leaning forwards.'
And finally, for Danny, who's 6' 4"ish the seat goes sufficiently far back that I can only just touch the clutch pedal!
All this is before we get into how much up/down movement there is on the seats, with the side-mounts.
Can't wait to get back out there on Thursday to get the harness mounts sorted.
