The back support portion of the rear seat will bolt up perfectly, but the lower part of the seat will have gaps on both sides. The gaps on both sides are probably 2 inches. And the metal bracket gimmicks that hold the lower seat down in the front will have to be bent straighter and over a tad so that they can fit into the slots of your eg. I have had gsr rear seats in my eg hatch for years and I personally like the look and don't have a problem with the gaps on the side.
Thanks,
Chris
