It was always our experience being many time NHRA National Record Holders(over 40 division and class records) and many time National Champions(11 NHRA National Championships) in professional racing and in the record books that kept us doing these mods. We didn't spend two days lightening our cranks if it didn't benefit us in faster ET's or more records. Other peoples experiences may vary, but for us and our many customers we also put in the record books, lightening the crank always improved performance numbers.
