I know they use a 3.5 Al one but what brand? Just curiuos because they list it for $800 which seems high but I like the idea of haveing more clearance so you do not bottom out once lowered like I have heard with the 4in pieces.
Also has anyone tried using a CF shaft? Those are only a little more than $800 I believe.
