Wheel Weight
Does anyone notice a behavioral diff of there car between wheels that are 18lbs vs ones that are 28lbs?
I know that technically perhaps 10lbs per corner may not have an impact on inertia and mass as the car itself weighs 3300, but does "unsprung weight" really have any validity as agian, the car as a whole unit wieghs more than the wheels alone.

yes
it's been said that unsprung weight reduction has 8 times the effect of normal weight reduction. The rotational inertia (or lack thereof) is very important for acceleration.

you have to factor rotational mass(weight x rpm x distance from center, for example).
10lbs per corner has a huge impact on the performance of your suspension, and becomes increasingly important as suspension travel is increased.

I thought of an analogy for sprung vs unsprung weight.Imagine running w/weight attached to your feet
