Seats are pretty important to me.
I know I've said this several times, but The ST1 seats aren't really all that bad. I have them in my 2012 SE with Sport package now and they are quite comfortable, supportive and grippy.
That being said, I still ordered the ST2 package just so I could get the partial recaros and upgraded stereo (the ST1 is the same stereo as what is in my SE Sport now, and being a guy whos put an aftermarket system in nearly every car he's had, I can't stand it anymore).
Every review (even though they were ST3 units) has been with the ST2 seats, which I find quite odd, I'm willing to bet that it's because the ST2 seats are just that much more grippy and if they're doing press cars, they want to make sure that the review have NOTHING to complain about, so they switched out the ST3 seats with the ST2.
I'll be hopefully seeing both ST2 and ST3 seats in NYC on the 30th on my performance academy slot, I am hoping that If I like the seats in the ST3 that much more than the ST2 seats I still have time to change my order. Essentially, I was told that as soon as my order is assigned a VIN, it's too late.
