They don't work for me either.Just out of curiosity, I just did some measurements from the steering wheel. When the seat is set so I can reach the pedals comfortably, legs at a comfortable angle, etc. With the steering wheel telescoped as far as it will go (as close to me as possible), I'm 17-18 inches from the steering wheel and my arms are at 140 degrees when at 9 and 3.
I ran the seat up to where I was only 11 inches from the steering wheel and my left knee was pressing against the auto pilot control stock, which would be a very dangerous way to drive. Both knees were at least half way up the steering column at that distance.
Basically those instructions posted above don't work for me. Just FYI.
