What did you do to your NA today?
how tall are you, im like 6.4
6'1" and I'm not even close to all the way back with the Kirkey. I have the room to actually go back another five or six inches with it if I needed. I was all the way back to the stops on the stock seat and it wasn't close to far enough. The Kirkeys are much more comfortable, too. I <3 them.
I actually added a small wedge of seat foam to the lumbar region that I had left over from making seats for my boat. Yes I dabble in sewing upholstery. The piece is triangular shaped and isn't sewed or glued in so it is movable and adjustable. My lower back is bad so I thought it was just me. The molded seat bottoms are quite comfy though and adjusting the lumbar for personal tastes is so easy Hyper could do it. No tools required. I find the Kirkeys far more comfortable than the stock seats even without the addition of the lumbar foam. Do like.
