I'm sure most of you are aware of my attempt to put WRX seats into my 06XT. I'm sure you're also aware that the WRX seat is not a drop in option for a passenger seat due to the occupant detection plugs being different. Well, I made one last effort last night to do it and I am happy to say that it's in and fits great.
And here is the airbag indicator with me in the passenger seat
What I ended up seperating the passenger side XT top and bottom of the seat. Then i took off the foam and seat cover of the bottom, and replaced it with the foam and cover from the WRX seat. The cover was not a perfect fit, but fits well enough that there aren't any obvious spots out of order. Once the bottom was together, I bolted the top half of the WRX seat to the newly put together mixed bottom (XT metal base and WRX cusion and cover). Now comes the modifications (they're not bad so long as you can use a Dremal. The lever for the reclining mechanism is attached to the back of the seat. Since I am not using the WRX seat I am forced to use the WRX recliner lever. This lever is much shorter than that of the XT. This causes a 3-fold problem. First one I encounter was that the shorter lever partially covered the area where the seat belt bolted to the base of the seat. I needed to Dremal off a good bit of the lever in order to get enough space to reattach the seat belt mounting bolt. Second, once the bolt was in it stuck out just enought to get in the way of the lever when the passenger wants to recline. I was able to fix this by slightly bending the handle to curve around the bolt. Third, the piece that comes off of the trim and covers the seat belt bolt is going to be fit to the original lever, and I forsee a bit of trimming in my future just to mae sure the motion of the lever isn't blocked. But that's a minor thing in my opinion. I will take pictures of this tomorrow.
As it stand how the seat are in and they look fabulous. I did not weld the lateral supports to the seat base because it wasn't necessary. There is reinforcment in the foam that offer lateral support. Not up to par like when using the actual WRX base, but much much better than the stock XT seat.
So, in the end, all I would have had to do is buy the WRX seats (and in my case the leather covers). The driver seat fit in no problem, and then since I reused the XT passenger base, the sensors were already there.
