Yes that's what I mean, I run the black stop bushing I think it gives 18°in the plate/mechanical...The other included bushings give you more in the plate/mechanical, I heard they were going to make a 15° bushing and some others never checked further on it. Not hard to set up, I run one medium and one light spring, they list all combinations and what the spring rate is so you can select what you want...You get the bushings and springs with the Distributor if I remember right...
