Tried a quick search- no luck: Does weight of wheels really make much of a difference?

My first stock eliminator car was a 2.2 fwd dodge shadow. The stock cast aluminum wheels and little mickey Thompson slicks on front and matching stock cast aluminum wheels and street tires on the rear were quite heavy. The rears where 39 lbs each and fronts were about 32 lbs each. I bought a set of Bogart flyweight wheels and mickey Thompson Et fronts for the rear. The new front wheels and little slicks were 21 lbs each and the 15x 31/2 on back were 19 lbs each. We did back to back runs on the same day at the Dragstrip, and went from 14.30s to 13.90s. So, yes the weight of wheels and tires can make a difference, especially in lower horsepower combos.
