Hi all
I submitted. this once drunk years ago and made a hash of it, so I'll try again.
I was disturbed by how close to the steering wheel the seat is, and noticed that the throttle is 'fly-by-wire' so can be moved anywhere.
So I made up a 4"by2" wooden test-jig, and when it proved to work fine replaced it with some metal box section.
This brings it out to near level with the brake pedal. Now you can have your seat further back so the drivers seat feels a lot roomier, which is good for long trips.
