The weight will have a whole lot less affect than loss of traction. I would find some cheap aluminum wheels, and some good drag radials, if you want to be competitive.
Beleave it or not the slicks and the street tires are on alu rims.
The street tires are on a set of turbine or fined rims that came on a old ford like a thunder bird. had to grind the center out so that they would fit on my axles.
If i had the money i would go by some nice light weight rims and some real sticky d.o.t tires........So have to make do with what i have kicking around.
