this makes a lot of intuitive sense. since brakes are 100% unsprung weight,
using lighter components would mean better ride which in turn can be
traded for stiffer suspension...

i have never figured out the math & physics for unsprung weight, just
that a teeny weeny bit of reduction goes a long way.
which mass, spring & damper model applies to unsprung weight? anyone?

well, that's not bad if you consider how much people are paying for
alloy wheels over steel...
thanks for the informative post!
