I see in that thread they are arguing about how real race cars corner weight with the shocks on. Normally I'm all for doing what they do in the real world but having a scale model that we are able to hold in our hands changes the rules a little bit. We can do many things much faster and in a much easier way. This is why we can do the spring rate tests by dropping the car or pushing down on the car while on real cars you can only tell by driving them. Perhaps it just never dawned on them to take their shocks off before corner weighting? It does require more effort though.
