I have them. They ride very hard but im not running a 125 lbs bumper in the rear yet but even when my spare bead lock and tire were in the back end (115 lbs) it still hits hard. I think it has more to do with the shock valving. The only issue I would see is the stock length rear shocks would be pushed to their limit (almost full extension) when the springs are installed. I would recommend the brake lines to be safe. I may be removing my rear springs and Fox piggies to replace with a standard height spring and bypasses. This way I will lower the front and get a super plush ride. As for flexing- that will come more from changing out the rear links which frees up the rear from the binding caused by the factory bushings. They are 20% stiffer than stock so they will ride firm but may fix your issue. They push my FJ currently to a 4 1/2" lift.

Hope that helps you.
