So yesterday I removed front passenger seats from my e92m3 and 135i.
M3 seats are with power/heated and 135i is manual, no power/heated.
Removed them right before the track season here, just for track days.
Very easy to remove, just unbolt 4 bolts and unplug the unit.
I was shocked how heavy the non powered seat was, if not the same, maybe 2 pounds lighter than powered one.
I think its about 65 pounds or so.
Going to remove rear seats too and about 110 pounds will be gone just like that.
Cheapest go fast mode I have ever done
