Since the dead zone is already out of the equation when it comes to buckling (i.e. the coils are already fully compressed), it really does not factor in to it very much if at all. We do not have a huge dead zone as we have stated in several posts as well.
The rate transition between the dead zone and the first spec'd ride rate is where the 2 doors ride giving them a little extra height and a little softer rate at ride height. However, when they get into it, the firmer rate is still the same.
The buckling equation is merely a function of spring geometry so changing the solid height will have nothing to do with it. Free length of the coil versus mean diameter. The longer the coil is, the more likely it is to buckle. That holds true for all of us since we are all constrained to the same coil spring diameters or they will not fit in the vehicle. Coils spring in general get forced to buckle under articulation since the coil spring seats are forced out of their proper orientation.
This is good review material. It has been a while since we actually spoke about this stuff.
Slade, we are not trying to bust your stones at all. You have an opinion and are more than entitled to it, but when it comes to engineering facts, it is best to stick to the facts. Good luck with your build or whatever you are doing.
