Tiger ride quality

asking some people that run similar wheel rates isn’t a bad plan

I was under the impression that different weight and springs of a car will give them different wheel rates...(wheel force vs wheel travel)....or maybe not....one guy has a 63 B body (coil spring?) and one guy has a torsion bar setup for a lighter car. I guess I am confused as to why ordering the same shock is a good idea. especially at that cost. Am I missing something here? No disrespect, you da man.
