I would like to get some feedback from some people with shock mounting experience. While going to college I worked on the suspension team for a SCCA scale formula car. We dealt alot in suspension geometrty. roll centers and "unsprung mass". I am questioning the later of those. For those who don't know "unsprung mass" is the mass of the suspension, wheels (ski's, upright and shock in our case) or tracks (as applicable), and other components directly connected to them, rather than supported by the suspension. Intern unsprung mass is the ammount of mass the spring and shock have to move to keep the ski's on the ground at all times. It would lead us to believe we would want to reduce this as much as possible to. This will allow the suspension to be more responsive in rough terrain. This is one of the reasons why Indy cars have the shocks mounted imboard (this also helps for aerodynamics at 200+ mph). I have notice on most sleds including mine, the shock body and spring support are mounted to the upright end. Wouldn't it make more sense to flip the shocks around. This would reduce the unsprung mass at the ski by several pounds (depending on the shock style). Does anyone have any thoughts on this. Does anyone know why Arctic Cat didn't change this. Maybe on a snowmobile everything is different.
