the original seats really have very little support for spirited driving
I have a different view from some others about the original seats, I'm not overly fond of them. In addition to not offering much support (as you described), I think they are too "heavy" looking. By that I mean too bulky and large for the tiny interior of the X. And they are very heavy in the literal sense as well. Personally I don't find them extremely comfortable but that is totally a preference. Style wise they look like pretty much most stock factory seats, fairly plain rather than true "sports car" (in my opinion). I think even if the covers were restyled they still would not appeal a lot to me, which is why I've removed them from both of the X's I'm currently building.I think i really need to come up with a new solution for X seats.
I definitely prefer the aftermarket seats you showed previously. Those are a classic sport seat style. And will offer great support. Again, purely my personal opinion, and I completely respect the opinions of others.
