After a longer drive (>20 min) I noticed that the seat was very uncomfortable. The side bolsters would push into the sides of my upper back, the shoulder bolsters pushed my shoulders and my lower back was killing me from the lack of lumbar support. I am about 6'2 240.
Took the BRZ to a local upholstery shop and they modified the the seat to my body. They shaved off some of the hard foam and replaced it with memory foam and added lumbar support. Now I can drive for hours comfortably.
