Corbeau or Sparco?
 

Anyone ever use either of these? If so, how is quality? I see that most of Sparcos seats are about 2x as much as Corbeau, so as of now, I will probably be going with Corbeau. I also really like the Corbeau Targa RS and especially the Carrera. I just want to make sure that when I do, quality/durability will be great. Also, I need to know how much lighter they are over stock seats, how well they fit, how's ride comfort, etc. Any other info is welcome. :)
