I was trying to keep it simple... Granted changing the suspension layout to S13 hardware could modify the motion ratio between wheel and spring, and modify the wheel rate when compared to the stock setup. This discussion is also incomplete without talking about swaybars, tire selection, as well as dampers.
I run 200f/250r with a 1" front bar, works well for me in combined driving. Is it that simple? No, weight, differential type, power band, my local track, etc. all played a role in me getting to that point. Does it work for MY setup? Yes.
Sounds like the setup you want doesn't need the wheel reinvented, I would stick to what works well for many, many Z enthusiasts. Coilovers, decent dampers, and spring rates as discussed forever on this forum if you use the search.
