I just installed two Corbeau Moab seats in my 2002 Liberty. Overall the seats are stiffer but also somehow absorb more of the bumps, and you definitely feel the seats giving-way less than the stock seats, i.e. I feel more stable when making or accelerating through a turn. I am also 6' 4" and I am not totally happy with these seats because I lost a few inches of leg-room! which I never expected and should have been warned about. The sliders that you have to purchase separately (Moab seats are not bolt-on for the KJ) are also 99 bucks a pop! As an aside, don't buy from SoloRacer.com because they actually sent me the wrong color seats (they sent some ugly color called Spice instead of Black! and were very rude and condascending towards me when I contacted them to return them). I didn't want to pay the $110 shipping to replace them so I just installed them. Overall they don't look bad, I'll take pics if interested. If I had to do it again I would go with the Corbeau VX2000 - you can get them in Leather if you want and they fit up to a 44" waist. Anyway, I can take photos if you are intersted.
