How much does the weight of the vehicle effect the 60'? If my car weights 3375 w/me and has a 60' of 1.37, if it was 400lbs lighter how much quicker would the 60' be?
all depends where the 400lbs was saved. If it was over the rear and you lose traction then it wouldn't help. If Its in the front or distributed evenly then you may get a better wieght transfer and improve or just stay the same and run 4 tenths of a second faster in the 1/4 mile.
