Yea, the GTIR seats are sweet but they aren't exactly easy to find here by any means. I was just sharing my experience with the Spec V's, I'm sure it isn't incredibly difficult to make a bracket for the rail that would allow it to be bolted down to the 4th bolt hole.
Anything is better than the heavy, ginormous WRX seats that came in my blue b14 that were only bolted in with the 2 bolts in the front
I had to go to the junkyard just to get the 2 brackets that bolt down under the center console to put B13 seats back in the car. That was a horrible idea on someone's part that will go un-named.
