I have a friend that got an FJ a few months ago. He tows a fairly heavy off road pop-up camping trailer with it. He really likes his FJ but is having an issue with the rear springs. He feels he's getting too much squat due to the tounge weight. Is their a way to correct this with aftermarket coilovers or a spring spacer? He doesn't want a lift do to the fact that their older and that might pose a problem in getting in and out of the rig. I'm a Ford guy myself so I'm not sure what the best fix would be. Bottom line is his rear springs are compressing too much with the trailer hooked up. Any ideas?
