While the gain will never be as big as tires, but I am curious as to what is the realistic expectation I should have for them. Now that I am stuck in this, wonder if I should go further and finish it off with the control arm. Or maybe I should just buy a fuel pump and get 12 gallons of gas off the rear of the car.
