The front segments are clamped and the slapper bars are slightly preloaded, so the front is fairly stiff. There is aluminum bushings in the front spring eyes, and there are no clamps on the rear segments, so they are free to separate (and do) on the launch. I only use 3 leafs to support the car so it's fairly soft to bounce the rear without the shocks, and the bars keep the springs from wrapping up. I think I may just buy some gas shocks to try and then upgrade to adjustables as necessary.
