I am mildly tempted for seats but have stalled the urge after I installed an old sheepskin cover on my bottom cushion. But I was looking at the Corbeau units which they have for a more affordable $600 a pair. (I think Summit carries them) They have a couple of units that are interesting, a set made specifically for a Razor and doubt not too hard to adapt with a flat bracket.
Edit= biggest challenge I have to buying seats is I want to put my butt in them before I give away hundreds of dollars! and I am sure the shipping return on seats is not cheap.
