what I tried to say is that lets say you have a 1000lb car with 500lb on the front wheels and 500lb on the rear wheels and 250lb/in springs on each corner


if you could move the springs (ie, adjustable perches), you maintain your spring ratio but shift the weight balance around... ie... corner balancing! But there is a practical limit to this, you're not gonna be raising the front 2" while dumping the rear 2" just to get the weight to the back in a nose heavy car because that would cause way more problems than solutions.


which is why you generally accept the F/R distribution for what it is and try to dial in the crossweight to be as equal as possible without upsetting the whole setup too much


if weight distribution is a problem, it is generally solved by removing crap, relocating crap, or adding ballast.




and more to your point, yes, the spring rates are there to achieve a desired wheel frequency for the intended application, which are impeded by suspension design and with tradeoffs being having to go stiffer to fight roll to achieve a better contact patch (not to be confused with reduction of roll!!).
