I did a 2/1 spacer lift with my 4R, and thought I had a slight bit of saggy butt, so I flagged down a guy in my neighborhood who has a lifted FJ, and asked him if he still had the stock rear springs. He did, and I bought those babies. It added about a .5 inch of lift in the rear, and I'm happy with the looks now. For now, I should say. I look at this website everyday thinking about what "real suspension lift" I'm going to do in the future.
