Yup, I do it for the launch. Not sure if it is scientifically or geometrically correct, just know that it works. I still prefer ladder bars. A 4 link is more tuneable, and that is both the good news and the bad news. I suppose for the street it is a much better unit, but for a predictable and repetive hard hit on the drop of the clutch it is hard to beat a set of ladder bars.
