As I understand it, engineers rely on a known sidewall deflection to act as the majority of the "spring rate" in the car. Little movement actually occurs through the suspension itself. I am sure there are more who know about this area specifically and in greater detail. My sneaking suspicion is that is why the resistance to even a 15" or 16" wheel as the loss of sidewall deflection would cause large scale re-engineering of uprights and suspension geometry and travel. Again, if someone knows better, please educate us tech noobs.
I don't think they will go for larger discs as that will only add more weight. Bigger disc might not translate to better braking performance if the wheels get too heavy.
So with narrow sidewall teams will have to run their suspension softer than what they are running now but with heavier wheels won't they have to stiffen it up. Or do they need just more suspension travel no need of softer setup?
The cheapest sort of pride is national pride, every miserable fool who has nothing at all of which he can be proud adopts, as a last resource, pride in the nation to which he belongs; thus reimbursing himself for his own inferiority.
