The Scott's damper is available in the following mounting locations, front fender, above the bar, and my favorite, sub mount which positions the damper below the bar. The sub mount raises the handle bar by 25mm or 1". Scott's will be more than happy to find you a set of bars that offset this 25mm rise if desired. Taller guys like me, who stand a lot like the 25mm rise in bar height.
The Scott's dirt steering damper only dampens from center out. This allows for quicker return, and no damper induced arm pump.
The Scott's damper also allows one to set how many degree's of damping from center out; 34*, 44*, 54* and 90*.
The Scott's damper has two damping circuits, low or base, and high speed. Each is fully adjustable. Just like suspension, with a little testing and homework you can make this damper work exactly how you want it, and, it is adjustable on the fly. I usually run my base valve 1.5 turns out in slower conditions, and 1 turn out in faster conditions. The less base valve (1.5 turns out) the more sensitive the High Speed becomes, and conversley the more base valve ( 1 turn out) the less sensitive the high speed is.
Unlike the competitions claims on their web site, the Scott's not only has a high speed circuit, just like your shock, but it is also tuneable, and it works.
