Marzman, I bought a 350z in April this year and at about the same time I started to experience bad pain in my lower back. I thought it was just a coincidence, but the last 10 days I was in central America driving a Mitsubishi pajero and I noticed that my back is now fine. Hence I am thinking about replacing the seats but thought I'd 1st search the internet to see if it's a known problem with the seats and here I am. My question is, have replaced the seats or bought a new car? If you got new seats, which ones and did it solve the problem?
