I just got the hpi big bores installed and noticed that there is a bit of slop in the upper cap from the pillow ball. It doesn't seem to be big enough. I'm not sure if this might cause some problems down the road, possibly a broken upper cap from the excess movement. Has anyone tried anything else, or different pillow balls to eliminate the slop? I also noticed there is some back/forth play in the upper shock area, but not to concerned about that.
