I've been really happy with the Corbeau GTS-II that I replaced my constantly shifting and worn Contour driver's seat with. Check it out at
www.corbeau.com. The seat and the bracket ran about $460. I think it was $399 for the seat and $60 for the bracket. I did have to take a Dremel tool to the bracket holes to widen them because things weren't lining up with the holes in the floor. But, once I got past that minor PITA, things are great. Very supportive, no squeaking, no moving. Maybe the only downside is if you're tall, I'm 6' 1", you might find the dimimished head room a bit bothersome. I think the Corbeau bracket raises the original driving position by about an inch or so. But, I've gotten used to it. Better than the worn seat I put up with for so long.
