Well the common thought is that (at least for handling) every pound of unsprung
rotational mass you shave off is equivalent to 10x that in sprung weight. so 5lbsx4 cornersx10 = 200lbs in total chassis weight. Can you feel the difference around the road course between having a passenger or not?
Now imagine shaving off 10 lbs off each corner. Yes, wheel weight is a big deal.
Unsprung weight by itself (shocks, suspension components, brake calipers) is a 4x ratio IIRC.
