not all of us are so lucky as to have power steering! j:
For me. well I probably sit completly wrong, but I sit where i find it comfortable. I tend to adjust if I'm going for a drive, generally bringing the back of the set up more.
But for daily driving, my seat is what man would regard as quite laid back. Infact you can see the headrest through the back drivers side passenger window very clearly! but of course I don't lean all the way back on it.
Anyways.
I generally have my seat where I'm comfortable to control the clutch properly, and my legs aren't too bent. ( I prefer my legs to be relatively straight) and the wheel in proper reach, where I can control it proper.My arms are hardly streching to reach the s/wheel but I'd hardly say they are bent either!
Thats just the way I do it. Comfort for daily driving is what I'm after.
