Hey, I'm new here, and some great info in this thread, but I didn't see anyone talking about this...
I just bought an '08 Si, and while I love it overall, there's one thing I really can't stand for long: the way the lumbar support is structured. Specifically, there's too much of it in the mid-lower back...I feel like something is jabbing into my midsection. Incredibly uncomfortable. I thought it was adjustable, but obviously it's not. Can anyone tell me if there are OEM seats (with airbags) that have adjustable lumbar support? Barring that, I wonder how expensive it might be to pay an upholstery shop to open up the seat, cut some foam out, then re-stitch the factory fabric?
