Well, I'm about 5'10". This was one of teh reasons I wanted to lower the seat some. The seat is more reclined then the stock seat from a naturnal position. (ie, when you put the both seats on the ground the Mastercraft will be reclined a bit. The front of the seat is a lot taller so if you don't have long legs it can be a problem. I'd actually like to lower the seat another inch or two for a better driving position. I don't like to have the seat too high.
I didn't get any options with my seats. I think with the angle they are at, there isn't a need for lumbar support. The seats have a really good angle. What makes them better? Everything. The seats weigh half as much and the original seats. Because they are a suspension design (think suspension bridge or hammock.) they are very comfortable. They have just the right amount of support without feeling too hard or too soft. Long trips are aren't a problem. (I've done one 500 mile leg and a few 700 legs.) When offroad or going fast through turns, the seats hold you in place a lot better then the original seats.
As for reclining; my original seats did no recline and I don't mind not having any adjustability in the Jeep. Once you get the right angle and height, the seats shouldn't need to be adjusted.
