Nice post, that is the same info I used in my decision, if it requires more lbf/in to compress the 919 spring, that means it will sit higher under normal load or loaded than the 912 or 913, which equals more lift Add a spacer, and voila, you are that much higher. But that requires that much more torsion bar crank as well. Its just a matter of what you want, and the ultimate reason, the 912s and 913s were a 6-8 week, 919s were in stock shipped the next day
