This is freaky. I came here to ask the exact same question that is currently being discussed.
I want to get down to 2 degree in on my S1/S2. So in lieu of ordering the aluminum parts and inserts, I got another idea.
Going to flip the front pivot mounts (on the rear of course) so that the holes are out instead of in. Wonder what my 3.5, 3.0 and 2.5 rears will actually end up giving me?
