I also did this "mod"..... It turned out to be the best thing I have ever done. I have only gotten 3 plates done so far, but the seats are still really solid. With a little time a some good drawing skills, it is done in no time. I hope I am never in a head collision, but I trust my welds.( I welded the plates on instead of fasteners) When I first drove around with these seats, I felt like I was in a whole different car. I got the seats for only 300 bucks so it didn't hurt my pocket book. One of the cheapest/best things I have done to my car.
