Has anyone tried one of the low price shocks from amazon? There appears to be quite a few and the common comment appears to be not enough dampening (based on the comment that they bottom out to easy). I was thinking about trying a pair on the back of my P500 that is a couple inches longer than stock, then set the sag so that the ride height is that of the original ride height. If the damping is too light I will use a thinker suspension fluid. My basic premise on the original P500 shocks is not enough sag for the shock to dampen in both directions and too much low speed dampening, is that an accurate assessment?
