Do you guys know if that whole phrase, "Reducing unsprung mass by 1 pound is
equivalent to reducing 5 (or 10) pounds of weight in the car," is really true?
I mean, I'm sure we've all heard it tossed around but has anyone ever shown
*definitively* (i.e. by experiment or by equations) that this is true? I could
have sworn I read somewhere that this weight savings is an exaggeration and
that really the ratio is like 1:2 instead of 1:5 or 1:10.  I'm curious how
much the unsprung weight actually affects the acceleration and other
performance aspects of the car...especially since many of us have (or plan) to
spend a lot of money towards getting light wheels and tires.  If 1 pound
unsprung = 1 pound "sprung", then spending $2,500 on tires/wheels to save 50
pounds doesn't seem worth it to me.
