It turns out Needsdecaf was right. Sitting with the seat cushion angled up somehow causes pain in the lower back. I switched to a more level seat cushion with a higher height, and the problem has gone away completely. Now I am very comfy and still have good visibility.

However there is something about the seat design in the BMW which is not optimal. I noticed in the BMW that when you raise the height of the seat, the seat also moves forward. i.e. full back is further forward when seated high than when seated low. This forces a trade-off between being too close to the wheel or too low. In the Lexus I sat in today, raising the height didn't move the seat forward. It was a much better design for creating a comfortable seating position.

It doesn't surprise me that your M3 has better seats - my old E46 M3 also seemed to have better positions available to me.
Are you guys bothered by the seat belt too? I can get the seat to a mostly comfortable position, but then the darn seat belt is around my stomach and I'm constantly readjusting it.

Any advice?
