I thought about the corvette seats, but they look too narrow when they are not in a vette. I looked a lot of seats before I settled on these. Gran Prix seats are pretty nice (almost got those) and Miata seats are ok too. I don't think they are too high at all, its just the angle. They may be slightly higher then stock, but no more than an inch. Thats a good thing for me, I'm pretty tall and the factory seats would only serve to break my neck in an accident.
Last pic, I'll say no more about it, this is Justin's thread about his awesome interior work.
