I still can put my seat back some from my saved/regular sitting position, have you sat in it and have an issue?
Are you trying to not have your knee/leg "hit" the center screen? If you are as tall, and/or large as I - there is no car w/ a center stack that your/my leg does NOT "hit" - to me it is more about /how/ my leg/knee rests upon the center stack in terms of comfort - Perhaps the ID.4 in comparison as it has no center stack/console below the "dash line" - I suppose if you are able to move the seat back your knee/leg then can go in front of the screen of the mach-e but I do not see how that would work if your still trying to get to the pedal.
There are rail kits that are universal online - they usually will raise you a 1/4 inch or so, as its just moving the anchor points... buy some bar stock and a threading kit and a metal drill bit..
I looked into this for my Nissan Leaf, but surprisingly I did not need to do so, I fit fairly well in that little egg car.
I am looking for possible options for this too. Or wondering if there is a stop adjustment from the factory that would allow another inch of travel. Longer trips my hip gets sore because of my leg angles. I plan on driving this car for many years and a little more adjustment for leg room would make this car even better. I found tracks for older mustangs, nothing even discussed online for the Mach E.
I am 6' 8" tall with a lot of my height in my legs. Headroom is great in this car for me.
