Lowest possible seats and rails
 

I'm looking to see if there is a seat/rail combo that will offer ~3" lower seating position from stock. I'm 6'2" with a long torso and my head is practically touching the roof.
From what I've seen posted so far Bride FO rails are the lowest with Bride Low Max or Status seats, but I haven't seen anyone posting just how much lower they are sitting.
I've noticed I can just move my seat closer and decline the seat as much as possible to gain a couple inches of headroom for a helmet but that would be a highly undesirable seating position for the track, or driving in general. Thank you.
