Finally I am nearly complete with my seat track install.
In order to have the seat perfectly centered relative to the wheel I needed to move the right hand side seat mounts inboard 1 inch to compensate for the width of the seat tracks. This allows you to move the seat right up to the tunnel in the same way as its designed by factory five without using seat tracks.
First I made and installed steel mounts and attached them to the frame.
Note when the seat track is fully back it goes into the stock aluminum panel so I needed to make a cut out and filler piece. I proceeded to bend up a few of these.
I got those all mounted up and painted the bare steel.
Got the stock panels trimmed and drilled
Then proceeded to test the seat travel. First fully forward.
Then fully back.
By tipping the seat I can move the seat back over 8 inches. Ill test with some of my taller friends to see how they fit. I think tipping the seat really helps in the head room department. I find it more comfortable as well. I can raise the seat and tip it back so I have plenty of room for a helmet and good ergonomics with the pedals, shifter and wheel.
To wrap up the shifter install I welded in the frame and painted it all up when it was done.
