It's not scare tactics, it is the truth and the risk you take with these kinds of mods. The 4 link rear suspension requires bushing and arms deflection for normal operation. Boxing the arms and using poly bushings hinders normal operation, not enhance it. It also just transfer the twisting to the rear control arm mount increasing the chance they will break. Just because you have been ok, so far, doesn't mean somebody else will. But the fact is you and others running boxed arms and poly bushings are running with an increased risk of snap oversteer, wither you accept it or not. Physics don't care if you accept them or not. The 4 link suspension is prone to wheel hopping and snap oversteer, wheel hop is the less serious of the two for a street or highway situation.
As I said before, there are no signs of snap oversteer, you just suddenly lose control without warning. What happens is with boxed arms and poly bushings cause binding. This binding causes greater understeer and a false sense of greater control and handling. If the binding suspension snaps lose out of the bind, then you violently go from understeer to oversteer which is difficult for even a professional driver to avoid crashing. So the only sign is you losing control without warning, that you stating never having any sign of snap oversteer betrays your lack of knowledge on the subject. If you have experienced snap oversteer, you would have likely crashed. Snap oversteer is most likely to happen on on and off ramps.
All I am saying is spend the little extra on arms with roto joints to avoid binding, which are simply a better product. They are also safer and perform better, what is so wrong about suggesting a better product?
