I know lighter wheels helps consumption and lowering will improve aerodynamics and wider tires will make it worse. But I am trying to gauge the effect of these.
I am planning to go from 20" PUP wheels to a 19" forged , so that should make the wheels significantly lighter and lower the car. However I am wondering what happens to the gain if I go from 8.5" wheels to 9.5" for the rear. Does anybody know how much of an effect each would have. Should expect to come out even?
Obviously I am not looking for an exact answer but wanted to know in general which has more of an effect. I guess offset of the wheels also would factor into this equation (since the 9.5" would sit wider)
